Hi,
I'm writing USB audio device (microphone) firmware, I want to use the USB audio
class driver instead of rewriting another one on my own.
Now, the device can respond to the requests issued by the host. But it just
fails after URB_FUNCTION_SELECT_CONFIGURATION with the result code 0xc0000004
(by viewing the log file of SniffUSB.exe). I doubt there's something incorrect
inside the descriptors, but I can't tell, I just copy those decriptors from the
USB audio spec "audio10.pdf".
Who can tell me how to debug the firmware with Window 2k/XP? Can I view the
debug messages from the built-in USB drivers? and how?
Regards,
Shiyi
