OK, I flooded hcd_endpoint_disable() and usb_hcd_giveback_urb() with printks and found out that the first get called when I unplug the device and it calls unlink1() with the correct urb then prints (with debugging enabled) "uhci_hcd 0000:00:07.2: shutdown urb cf02bb00 pipe c0020480 ep4in-bulk" it goes back to "rescan:" then the list of URBs is empty and the function returns. The usb_hcd_giveback_urb() on the other hand never gets called with the URB of interest. It is not quite obvious to me where to go. If you could tell me the missing function calls "between" endpoint_disable()/unlink1() and giveback_urb(), that would be helpful.
