CP210 chip, Can we communicate with this board , with baudrate = 921600 ?

I want to reiterate what solves a common issue with this board.

I was trying to simply interface a USB keyboard to an Arduino and having one weird issue. It would work on a RedBoard but not consistently. Randomly it would just stop working and swapping USB devices did not work at all. On an Uno I got the "OSC did not start." consistently. :@

PIN 7 of the Arduino is tied the reset pin of the MAX3421E. If this pin is not set to OUTPUT then it will drift causing the MAX3421E to reset at random. If you are using the USB_Host_Shield_2.0 code that everyone points to then this pin is not set by default. Simply put this code before Usb.Init() in your code and all your problems will be solved!

pinMode(7,OUTPUT);
digitalWrite(7,HIGH);

Can I connect this shield with the ESP8266 (i.e. Feather HUZZAH ESP8266)?

This board appears close-up in the Arrow episode "Second Chances" (season 5 episode 11) at about 29 minutes in. :-) Rotate your head about 150° for a clear view of the "sparkfun.com".

I want to send some data from arduino to computer using this shield. Do you have any hints or example how I can do that? There are many examples for communication with other devices like android but I can't find any with PC

I had an issue with unstable operation of this board + USB joystick + Arduino Uno. It worked for a while, then stopped. After some debugging with scope I realized that there is no 3.3V -> 5V voltage translation on MISO pin. * MAX3241 Voh = VL - 0.4V = 2.9V. * ATmega Vih = 0.6Vcc = 3.0V This board does not have to work with 5V Arduino boards. Adding LVC1T45 voltage translators between MAX3241 outputs MISO and GPX and Arduino pins D12 and D8 Seems to fix the problem. Schematic is here

I want an Arduino and an Android phone to communicate to each other. I bought the USB host shield, downloaded the library available at the link "Projects and Code", wrote an Arduino sketch and Android app according on what I found on the internet related to this issue. I found some compiling problems that got fixed thanks to the tips I found on the internet, but in the end, it doesn't work. Once the sketch is downloaded to the Arduino board and the app to my mobile Phone running Android 4.4.4, I connect both devices by means of a USB micro B cable, and nothing happens, when supposedly, this should fire the app start up. I don't see either any print out in the Serial Monitor from the Arduino side. Can anybody tell me what I am missing or send me to a proper forum?

I bought this board to use with a wired Xbox 360 Controller or Xbox 360 Wireless Adapter but neither of the two get recognized by the board. The only USB device that seems to get recognized is a Belkin USB WLAN dongle. I am using the board with Arduino Uno Rev. 3... What am I missing?

How do your boards solder so well? I seriously sling hot solder form across the room and your boards soak it up in the spot I wanted, what are you doing differently with the production these thru hole PCBs?

Nice shield. It tooks some times for me to find and fix an issue with USB host library running on UNO. Reset pin 12 of the IC on this board wired to dig. pin 7, and it looks like as another citcuitsathome 's board has reset tided up to reset of the arduino board, nobody care anymore about status of the digital pin 7. And of course chip is in RESET, because there is "0" - active at this pin. To fix, simply add two lines in your sketch setup(): pinMode( 7, OUTPUT); digitalWrite( 7, HIGH);

Although I bought the latest USB Host Shield, I mostly had the "OSC did not start" message while trying the HIDkeyboard library. I added the following code in my "setup" function and now it works correctly :

//Workaround for non UHS2.0 Shield 
pinMode(7,OUTPUT);
digitalWrite(7,HIGH);

(I found this into the USBH_MIDI library )

It should be noted in the description that the shield does not come with headers installed

I guess I have to solder the pin's to the shield myself

I have this shield (DEV-09947) and now need to use it with an Arduino Mega 2560. After reading various posts around the Net I'm still uncertain about the compatibility between them and if there is any change to put in the code for driving the shield with Oleg's library 2.0 (felis-USB_Host_Shield_2.0-96d506b).
Can someone shed the light for me?

Will this play nice with the micro sd shield (http://www.sparkfun.com/products/9802) ?

Hi,
I just got this Shield.
Like some of you, when I tried to execute the board test sample I got the following error :
Error: OSCOKIRQ failed to assert
Circuits At Home 2010
USB Host Shield QC test routine
Press any key to continue…
Reading REVISION register…Die revision invalid. Value returned: 00
Test FAILED!
Test Halted.
0×55 pattern is being transmitted via SPI to aid in troubleshooting
Press RESET to restart test
I’am using USB Host library downloaded with the name felis-USBHostShield-a59ba5b.zip.
I tried to change MAX_GPX and MAX_RESET to #define MAX_GPX 7 #define MAX_RESET 8 but problem still persists.
I use an ATMEGA 2560 linked to my PC and an external +9V power supply.
(SPI pins are correctly connected according to atmega2560 specification)
Thanks for your help !

My power LED does not turn on when power with a 9-Volt source or via USB. I have voltage at Vin, I have voltage on the other side of the switch when switched on. It looks like the LED might be installed backwards. Anybody else having this problem?

I just got this board and can't seem to get it to work. I am using Oleg's code and receive this message: "Error: OSCOKIRQ failed to assert" I am using the Mega 2560 with an external power supply. I have read everything I can find about this and have tried everything suggested, but no luck.

This shield will not work with Arduino Mega, since mega uses different ICSP pins. This shield has ICSP routed to SS-10 MOSI-11 MISO-12 SCK-13 while mega uses 53 51 50 52 respectively, so to get it to work with mega you will have to make changes in hardware accordingly.

unsure if this has been asked, before and I missed it below, but is there a mini version to the USB host shield? I'd like to interface it with an xbee-R shield and a pro mini, and a 360 controller for a quadcopter RC build...conceptually, is that doable? without something so...bulky? :)

Can I use it to communicate Arduino Leonardo with an Android tablet. My tablet only has mini USB connector. I would like to control the tablet with the arduino.

Hi, I bought a board last week. To give it a kick start I downloaded the library USB_Host_Shield_20. When I compiled the code board_qc, to check the board, it gave me several errors:

Anyone have any idea on how I can get rid of these issues? I'm using an Arduino UNO board. After these errors remove I can start with connecting the board.

Is it possible to use USB Host Shield together with CAN-Bus Shield ?

hello, my shield is not working anymore and the MAX3421E chip gets really hot.. what could be the reason?

just a stupid but important for me question where can i get the exact pin configuration of this board? the links given here seems to be for a board having a different layout than this one

Does this works for the mini arduino pro?

Could this be used on a Mega so that instead of using the Uno's D10-13 pins to uses the Mega's D31-34?

Is this compatible with Arduino Mega?

Hey everyone I tried running USB host shield by Sparkfun on Arduino Mega. I Updated the libraries by changing

define SCK_PIN 52

define MISO_PIN 50

define MOSI_PIN 51

define SS_PIN 53

also changed

define MAX_SS 53

But still I'm getting Error: OSCOKIRQ failed to assert. Can anyone help me with this. Thanks in advance.

Shield works great! A couple tips to help others avoid the stumbling blocks I hit:

(1) You really do need to jumper the RESET pin to 7. Sounds silly, but if you're seeing "Error: OSC Did Not Start" or a variety of other errors, this is your fix.

(2) For my application, I was using a mouse with a 1ms poll rate. The Host Shield Library (v2) has a default 10ms delay between polls. That sucks! To fix it, I edited "hidboot.h" in the library. Near the bottom of the file, look for "qNextPollTime = millis() + 10" and change the 10 to a 1.

(3) Not all the mice I tried played nice with this shield. The Razer Taipan is the one I ended up using. It has an absurdly high DPI and AWESOME drivers that you can use to tweak firmware settings like DPI and liftoff distance. The taipan is pricey, though -- if your application doesn't require these things, try something cheaper first of course.

Happy hacking!

I have tried using USB host Shield with Arduino uno with a joystick. But I'm getting an error Data Packet 9. Can anyone suggest me why this error is coming?

I was not able to get Oleg V2 library to work on the shield until I put the jumper from D7 to RST. Initially, hesitated to put the jumper, but after I read all the comments and I looked at the schematics. I realize that Oleg V2 Library should be resetting the RST line if it is not using Pin D7 to do the job. But make sure you do not connect the D7 on the shield to the Arduino. You only connect D8-D13 to the Arduino, otherwise you will be shorting the Arduino D7 to RST. If you set Pin7 as output and high, this should also prevent Pin D7 from resetting Arduino (if D7 is still connected between Shield and Arduino).

I got the shield working with a PS3 remote using a usb cable and all readings are fine. How ever when I connect a usb dongle that came with a bluetooth mouse I bought there is no connection between the two. The mouse on the other works fine.

Do I need to buy a new usb dongle for the shield to comunicate with the PS3 remote?

Hey guys,

I'm playing around with my new USB Host Shield and have encountered a problem. I am simply connecting different optical mice to an Arduino Uno through the shield. I have got 1 (let's call it mouse A) up and running. It displays right/left/middle button presses and delta x's&y's for movement. I have a second mouse (mouse B) with the buttons working, but I cannot get the movement to display. On a guess, I probed my USB lines directly and noticed that neither the VBus pipe or the optical sensor Vss is at 5V. They both are running at 3.38V at the moment. I suspect that mouse A can function at that voltage but mouse B actually requires 5V to use it's optical sensor. Both data sheets for the optical sensors in each mouse state 4.25-5V for power supply. The USB Shield description says it provides 5V to the Vbus line, but maybe I missed the part saying you need to do steps A and B for that to happen.

1) Any suggestions on what might be going wrong?

2) Can I safely route a 5V line from my Arduino directly to the Vbus of the USB on the Shield? I figure it would be better to cut the existing Vbus line if I can find it, and then attach the 5V line from the Arduino. Thoughts? I'm worried that the MAX3421 reads a voltage level off the Vbus line and if I cut it, nothing will work.

Thanks guys!! Ben

I already have an Ardweeny, a kit from Solarbotics that uses an ATmega328 fyi, and was wondering if this can be used with that while the Ardweeny is still using an FTDI basic breakout board. I'm still very new to USB hosting and would like to just use what I already have while simultaneously having separate host and slave buses from which the Arduino can still be programmed. Fingers crossed that somebody here can help me, and thanks if you can.

hello i bougth a usb shield from sparkfun and a motor shield from maker shed when i connect both separtly to the arduino uno i got them to work. But if I stack them together they stop working. How can i find out if there is a pin problem?

Not sure why you are selling these when Oleg himself doesn't support them.

I'm seeing "sketch too big" is there a work-around...when compiling wii example

Hi, regards from Argentina. I have my Sparkfun USB Host translating USB MIDI to Standard MIDI. I use a nanoKey to play my Monotribe (both from Korg) using both Oleg and Yuuichi Akagawa libraries. Everything OK with this. But I connected a Korg microKey 37 and the shield doesn't even power it up. I tried to conect just data and GND to USB HOST and power it from an external source and nothing either. Any experience out there using USB MIDI controllers with this shield? Any suggestions? Thanks in advance! Jorge

Can this shield be used on a second Arduino to recieve USB data from an existing Arduino that is already sending out serial data on the USB (normally sent to a PC)? For example, my original project is sending out data to the USB port which is normally used for viewing the data with a PC, and all of the original project's Arduino pins are used up in the project (no spare pins to create a simple serial connection). If I want to add a second Arduino with a USB Host Shield to recieve data via the original project's USB and display that to a serial LCD, is this USB Host Shield capable of hosting such communication? I think that a "stand alone USB viewer" would be a neat tool to have when I want to temporarily view the serial USB output of an Arduino project without connecting a PC to my existing projects.

I can't tell if the shield is defective or I'm using a wrong/incompatible library (usblib2.0 from Oleg). Is there any recent code example?

I'm unable to initialize this board with my Arduino UNO.

The board_qc example from the 2.0 library gives the following:

/************ Circuits At Home 2011 USB Host Shield Quality Control Routine Reading REVISION register... Die revision 03 SPI long test. Transfers 1MB of data. Each dot is 64K Test failed. Value written: 01 read: 00 Unrecoverable error - test halted!! 0x55 pattern is transmitted via SPI Press RESET to restart test ********/

The board's revision can be read but data can't be written to the board. Usb.Init() will give -1 and examples say that means ' osc did not start'.

1.0 Library also fails to start. I'm worried if I burnt something I shouldn't while soldering the headers to the board.

Any ideas?

Hello, I wanna connect this shield to control a fax-modem (AT Commands). The modem uses the Conexant CX93010... Can anyone tell me if the instructions on "Interfacing Arduino to a Cellular Phone" can work on this case?

Suggestion to Sparkfun... you should add a note to your shields about compatibility with Leonardo. I burned a fair bit of time trying to figure this out. While there is some info on the forums, you actually have to do a bit of digging since the Leonardo is new.

I have spent an afternoon trying to get this board to work with a Leonardo. I just discovered that Leonardo will not work with it it doesn't have the SPI lines on pin 10, 11, 12 and 13 but only on the ICSP header.

Is there any way I can get around this without buying a different Arduino?

Hi People I've been googling the whole day find any piece of code that can used for writing data on a USB flashdrive connected to the host shield. I've got the 2.0 library working but there aren't any examples of writing to a USB drive connected to the host shield

I'm surprised I coudn't find any code. Has anyone managed to do this?

Can I use it with the ardumoto shield? Or, they use the same pin?

Greetings,

I haven't received my board yet, but based on the photos, it looks like there is a simple trace on the Sparkfun PCB that connects arduino D7 to the 5 volt to 3.3 volt level-shifter chip. I plan to carefully cut that trace near the arduino D7 pin, and then jumper the arduino RESET to the level-shifter side of the cut trace. This seems safer -- I don't like the idea of RESET and D7 being shorted together... bill

I can also confirm that I have been able to get everything working with a 328 and a jumper between D7 and RST. All good. Just in case no one has spotted the little on/off switch next to the USB socket I thought I'd mention it as you tend to get a failure when its like off... i.e. not on. :)

What a fantastic board and what fantastic code by Oleg.. simply stunning.

Attention: The only way to get this to work with Oleg's code is to jumper D7 to RESET. After that everything works perfectly. Also, if you run the board QC code, ignore the warnings pertaining to ground pins, they are not important.

Help! Can I use this dongle with this shield? It would seem that this would be a cheaper option for swapping in and out inexpensive USB modules instead of using larger boards. I want to connect via Bluetooth to a Palm Pre Plus.

Circuits@Home has a USB Host Shield Ver. 2 that they say is compatible with the Mega. I prefer the Sparkfun design. Has Sparkfun given any thought to producing a Ver. 2 of their own that resolves the issues discussed in some of the other comments? Lack of compatibility with my Mega is the only thing standing in the way of me ordering one. I may not be alone.

Hi,

I have connected the pin 7 to the reset and soldered all the GPIN connections from GPIN0 to GPIN7 and GPIN1 to GPIN6 and so on. I am getting the below mentioned message for the board_qc

ÁE- Circuits At Home 2011 USB Host Shield Quality Control Routine Reading REVISION register... Die revision 03 SPI long test. Transfers 1MB of data. Each dot is 64K................ SPI long test passed GPIO test. Connect GPIN0 to GPOUT7, GPIN1 to GPOUT6, and so on Test failed. Value written: 00 Value read: 10 Press any key to continue...

Have i made some mistake in the GPIN connections. As I was making the connections I kept checking the value read and it went from FF to 10 but not to 00.

Is there a way I can check which pin has the mistake ? Please help

Hi,

I soldered the connections and also the Resest pin with the pin 7. When i run the board quality check code of Oleg, the SPI test is passed but the GPIN test is failed. Are the GPIN and GPOUT pins connected on the board or do i need to solder the connections for them as well. That would definitly make the board too messy.

BR, Muhammad

I have just recieved the USB host shield but I am unable to figure how to connect it to my UNO. I have seen the schamtic but it shows the lay out of the USB Host. Which pin of the UNO i have to solder with USB host shield board. Can anyone please guide me ?

Hi All, I got the USB Host shield, together with the Nokia LCD shield and it works great. But the LCD shield stacked on top of hr USB shield does not work. Some port conflict? SPI adress? Is there anything I can do about that??

Arjan

Can you plug a hub into this shield and connect more than one device or is it restricted to a single host device?

Just got mine and forgot to order the shield connectors. So I'm asking this in advance before being able to check it myself and fry the shield. To be honest, I would like to know why wiring pin 7 RESET to RST is necessary at all? But slowly ...

I've read the comments about wiring the shields pin 7 RESET to Arduino's RST pin. So far so clear ... really? Why is this necessary at all? The datasheet says that the MAX3421E has its own internal POR generator. As far as I could see from Oleg's sources, all he does is a "soft" reset through the appropriate register accessible via SPI. And this register does not touch SPI communication, as also pin 7 RESET/RST does not.

So what can be the reason for Oleg's library and QC sketch to fail at all? There has been the (independent) POR and contrary what other wrote here, there is no pulling the Arduino's RST low as this would also reset the Arduino and restart the QC sketch or whatever. Someone a working explanation?

The Usb::init() method just issues a bmCHIPRES to rUSBCTL, then clears rUSBCTL and waits for bmOSCOKIRQ to become set in rUSBIRQ. There is no fiddling with RST/RESET at all. It just spins and waits for the for the bit to become set.

Any why is there the hardware RESET pin 7 at all if there is the really equivalent bmCHIPRES? Does the latter have issues and is not reliable? But then, the QC should also fail...?

Does this version work with Arduino Uno?

Which pin should i digial read?

Be careful with this mod - apparently, it fries pin 7. After I made this mod, pin 7 stays high permanently and can't be changed with DigitalWrite() even if I remove the wire.

If you read the comment's in the section Interfacing Arduino to a Cellular Phone on Oleg's site, he say's that his software does not work with Sparkfuns USB Host Shield, it only work's with his version of USB Host Shield and you can buy it fro his site. Just follow the link to "Projects and code" on this site. This is not funny because Sparkfun is linking to Oleg's code and no alternative exist's.
Please correct me if i'm wrong, i really want to get a Sparkfun USB Host Shield to work with Oleg's code or i have a USB Host Shield that i can't use and need to by one from Oleg.

I got this USB host shield working with version 1 of oleg libraries at https://github.com/felis/USB_Host_Shield
Have anyone got this sparkfun usb host shield working with Version 2 USB Host Shield library ?
Thanks

Good news - Circuits@Home lowered the price of the original shield to $25! 100% compatible with Oleg's code :-).

I've purchased and received this board, for the sole purpose of making a sensor that has a USB Device (Type B) interface wireless using an XBee.
I still have a lot to figure out, but I have a questions as I begin to gather resources and information to complete the task.
When I navigate to the "Projects and Code" link there is a wealth of information to access, but none of it refer specifically to this shield.
Can I assume the electrical connections are the same between this product and what is covered? If the discussion and software don't match where can I find out the difference to avoid a trial and error process?
Thanks

Hello, I was wondering if someone could help me with a problem I have with this shield. I just bought it and can get it to work. I have ran the board_test and descriptor parser but all I get form the serial monitor are some strange characters. I am using an Arudino UNO with an external power supply.

Hi folks.. I have one of your usb host shields. I've been trying to use it with a 328-based duemilinova and Oleg's code (Thanks Oleg).. but I've not been able to get it to successfully talk to anything. I've tried a samsung tracphone, a moto v220 a blackberry 9630, a moto droid 2 and a canon powershot camera.. Neither Oleg's acm_terminal or hub_demo packages can connect.
When I try Oleg's board_qc I get the following report

I'm using this shield (new version) and a duemilanove. I'm using usb host 2.0 library, and the SPI long test fails every time. (short test runs, die revision 03) My understanding is that the reversed reset and gpx pins were resolved, but I still get "Test failed. Value written: 01 read: 00" on the long SPI test.. if I comment that out and allow the other tests to run, I get GPIO test passed, current oscillator state unexpected, then "OSCOKIRQ failed to assert". I do have external power connected as well, 12v 800mA. Any ideas? Much appreciated in advance =)

I can confirm that the Sparkfun Ethernet shield works with the USB Host Shield. To make mine work with Oleg's legacy code:
1. Cut USB Host Shield PCB trace going to IO pin 10.
2. Wire the PCB trace to pin 6. (this is the trace that used to be hooked to pin 10).
3. Change #define MAX_SS 10 to #define MAX_SS 6 in Max3421e_constants.h
4. Supply a hefty source of 9 volts to the Ethernet shield. Running from the USB power is not enough!!!
5. Run board_test.pde. Monitor using the serial monitor with monitor speed set to 115200 baud (the drop down menu in the lower right corner).
The Sparkfun Arduino ethernet regulator is almost too hot to touch. Using an IR thermometer I measured 150 F on the regulator and 180 F on the reverse protection diode D1 feeding it.

Hi,
Some days ago I bought the Arduino UNO and I'm really satisfied. Today I got the USB Host Shield. With the fact, that I'm very new to this stuff, I had to spend several hours to get it work.
At first I got the "MOUSE"-Code to work, but after some other code-tests i got lost with the same error "setup packet error:d". Even if i tryied the first code again.
Then I finally found out:
Before testing I bought a new Block-Battery (E-Block, 9V). To save some money I took the cheaper one (VARTA Superlife).
When I was about giving up on that, i connected the arduino to my "Laboratory power supply". Finally ... it worked !?!? So i checked my Battery with my multimeter. Instead of 9V it only gave me about 7.3V. I think there was the problem. When i lowered the V on my "labor.pow.sup" i got the same error (setup packet error:d). Switched back to ~9V ... and it worked fine again.
Perhaps I helped someone with that Info.
(Damn you VARTA SUPERLIFE!)
But I'm really new to this stuff, so it won't mean much.
bye,
zacharias

just got the board in the mail. attempting to use Oleg's codewith no luck; keep getting stuck on testing the SPI. I noticed the led on the usb device is not going on. could this be the problem? is the device not getting power?

Hi all!
I have an Arduino UNO and this USB host shield. I would like to receive messages from an AKAI EWI USB (MIDI wind controller), similar to this project: http://blog.makezine.com/archive/2010/11/usbhacking.html.
A first step was to change the code of the mentioned project., among which the USB device description. I was able to use the description parser example code from Oleg for a USB mouse and camera but when I attach the EWI, I get following error messages:
Setup packet error: D
Device addressed... Requesting device descriptor.Setup packet error: D
Request error. Reurn code: 0D
Device descriptor cannot be retrieved. Program Halted
Also, the power led on the EWI does not turn on when plugged in (which it does when plugging it into a computer).
Any ideas on what the problem might be? (I'm powering the Arduino with a 9V power adaptor and the EWI uses a type B USB cable (although I don't think this makes any difference))

Any example code to read/write files to/from thumbdrives?

Can this be used in conjunction with the Arduino Ethernet Shield?
I have a feeling that it won't work (well), because it uses pin 10 (which the ethernet shield uses as well) -- perhaps it would be modifiable?

Could someone please confirm that this board plus 2 Arduino Stackable Header - 8 Pin , sku: PRT-09279, 2 Arduino Stackable Header - 6 Pin ,sku: PRT-09280, plus a Duemilanove would enable me to do Android ADK development.
TIA,
Paul

Item is on back order, looking forward to getting my Android app to work with Arduino via this when it comes in. On the notify list but it has been out of stock for a while.

I have a USB GPS and want to connect it to an Arduino. With this board, Oleg's code and an Arduino will I be able to do this simply or is it going to require a lot of coding for the GPS and host to communicate?

I was concerned about some of the comments above but I just received this and have it working fine with an Uno. Please note that I needed to use the version of the code from Oleg that uses built in SPI functions. My download was named felis-USB_Host_Shield-a59ba5b.zip and I presume the a59ba5b is a label for that version. Also note that there was enough voltage on the USB connector without connecting the DC jack to run a thumb drive but not a mouse. For that I did need to provide power to the Uno via the DC jack but that worked fine.

ok so im wondering if i can build this on a bread bord or something cuse im on a budget what parts would i buy to make this

I use the Arduino who came out before the Uno design, not the Mega 2560, which is the Duemilanove. Are all of you stating that this fellow would need to be externally powered to participate with this shield?

Hi,
I've got problem with this shield and board test program.
I got this in console :
Error: OSCOKIRQ failed to assert
Circuits At Home 2010
USB Host Shield QC test routine
Press any key to continue...
Reading REVISION register...Die revision invalid. Value returned: FF
Test FAILED!!!
Test Halted.
0x55 pattern is being transmitted via SPI to aid in troubleshooting
Press RESET to restart test
I am using Oleg's code, with Arduino UNO and 9V external power + arduino linked to computer

I've been unable to compile the Arduino camera control stuff. The directory structure of the source code has been changed but not saved with the zip file. There seems to be a 'time.h' missing as well.

Word of caution: Check the voltage that you are feeding to the USB device connected to that shield!
Using a USB powered UNO will not result in 5V on the USB bus!
If you are using a UNO make sure to use a 9V power adapter, even if the UNO is connected to your computer via USB.

I have problems too with this board. First it worked intermittently. Now not at all although the programming was not changed.I used an oscilloscope and a protocol analyser to trace and there is no SPI response from the MAX chip. Can someone confirm he had the same problem?

It should be made more clear that you must supply and solder your own headers to connect to the Arduino board. It's not mentioned in the description or the data sheet.

I too am seeing errors; however, I'm running the USB board test on a Uno. Oleg mentioned that he thought there might be some compatibility issues with this board and his code. I'm not sure if the corrections listed above (GPX and RESET pins) were supposed to address that.
