It looks like there's some problem in the usbhid driver. Apparently hid_start_in() gets some sort of error when it submits the input URB, because that URB doesn't show up in the usbmon output. Can you add a debugging line near the end of hid_post_reset() in drivers/hid/usbhid/hid-core.c to find out what the return value from hid_start_in() is?
