I have a commercial webcam based on EZUSB - FX2. I still want to use the
camera, so i don't want to make any changes (like disconnecting the
seeprom). I hoped that using the vendor command A0 i could bypass the "C2"
SEEPROM. I'm able to upload my code and have it running. It seems that after
i take the cpu out of the reset i cannot disconnect and reconnect the device
by "bmDISCON". That is, the device disconnects, but it NEVER reconnects. Is
this behaviour caused by the SEEPROM?
If you can't fix the reconnect issues, you can mutilate the camera by
overwriting the first byte of the EEPROM. This will put the FX2 into
default mode and also eliminate any possible side-effects from the
camera driver (won't get loaded without the PID). Once you're done
with your job, you can restore the original first byte from your
backup, and the camera is good as ever.

Marc
