Running the driver in debug mode with -DDDD for 20 seconds or so should
provide enough information to determine if the bug is the same as I
fixed in the patches Charles mentioned. The only other thing that would
be needed is the USB ID because the patch restricted the fix only to the
models suffered from it.
