Hello,
I am sure this is not a novel issue, but I have tried the suggested fixes to no avail.
I purchased the DEV-09947 version of the SparkFun USB Host Shield but I have no idea of knowing if it is in fact the correct revision. The only thing printed on my board is a date: "5-28-10".
I have my Arduino Uno hooked up to my PC via USB and it also has an external 9V regulated supply DC jack connected.
After uploading "board_qc", the serial monitor shows the following output:
Circuits At Home 2011
USB Host Shield Quality Control Routine
Reading REVISION register... Die revision invalid. Value returned: 00
Unrecoverable error - test halted!!
0x55 pattern is transmitted via SPI
Press RESET to restart test
This message does not go away if I jumper D7 to RST.
Wondering if anyone has any suggestions. Thank you!
SOLUTION
1) Check what SparkFun board revision you have
2) If DEV-09947, you don't need to make any jumper connections
3) Add the following #defines in your sketch along with the code below it in void setup()
//Revision 1.3 (DEV-09947)
#define MAX_RESET 7 //MAX3421E pin 12
#define MAX_GPX 8 //MAX3421E pin 17
void setup()
{
** pinMode(MAX_GPX, INPUT);**
** pinMode(MAX_RESET, OUTPUT);**
** digitalWrite(MAX_RESET, LOW);**
** delay(20); //wait 20ms digitalWrite(MAX_RESET, HIGH);**
** delay(20); //wait 20ms**
** ...**
4) Plug in your USB device/keyboard/etc
5) Make sure switch on SparkFun USB Host Shield is in ON position
6) Run board_qc or USB_desc to test with Arduino Serial Monitor

Thank you, I have now been able to get passed my last hurdle and have been met with another.
This code setup below worked for me, while the opposite did not.
//Revision 1.3 (DEV-09947)
#define MAX_RESET 7 //MAX3421E pin 12
#define MAX_GPX 8 //MAX3421E pin 17
adding the following under void setup():
pinMode(MAX_GPX, INPUT);
pinMode(MAX_RESET, OUTPUT);
digitalWrite(MAX_RESET, LOW);
delay(20); //wait 20ms
digitalWrite(MAX_RESET, HIGH);
delay(20); //wait 20ms

Checking USB device communication.
Waiting for device...
Plug in something simple such as a USB keyboard. Or try the USB_desc.ino example program.
I finally got this to work and it turned out to be a silly oversight on my part.
I didn't realize that there was a physical ON/OFF switch on the SparkFun USB Host Shield board. Once I turned it into the ON position, after making the above code changes, everything worked and my USB keyboard was recognized using both board_qc and USB_desc files.
I also confirmed with SparkFun and my board is a DEV-09947 revision.
In summary:
- Check what SparkFun board revision you have
- If DEV-09947, you don't need to make any jumper connections
- Add the following #defines in your sketch along with the code below it in void setup()
//Revision 1.3 (DEV-09947)
#define MAX_RESET 7 //MAX3421E pin 12
#define MAX_GPX 8 //MAX3421E pin 17
void setup()
{
pinMode(MAX_GPX, INPUT);
pinMode(MAX_RESET, OUTPUT);
digitalWrite(MAX_RESET, LOW);
delay(20); //wait 20ms digitalWrite(MAX_RESET, HIGH);
delay(20); //wait 20ms
...
- Plug in your USB device/keyboard/etc
- Make sure switch on SparkFun USB Host Shield is in ON position
- Run board_qc or USB_desc to test with Arduino Serial Monitor
Thanks again, gdsports!
