USB Host Shield Arduino Uno R3


I have troubles with my arduino uno R3. I would connect it with an usb host shield.
The host shield is the type of circuit@home. If I connect it with the arduino al the lines are connected. (I test this)
After this I tried a lot of programa's but every standard program of the libary usb shield 2.0 gives me an errer:
"OSC did not start", somewhere on the internet there was someting about the D7 pin and reset, tested this and doesnt work even.
I also found an tool board_QC and tested this, with the following results:

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

Can anybody tell me if I have to change something in the libary or is my usb host shield broken / "burned"??

Thanks a lot!!
