Marcel:
Now that usb_kill_urb() is in Greg's development tree, stimulated in no
small part by the changes needed for the USB Bluetooth driver, those
changes can be simplified. I don't know when usb_kill_urb() will make
its way into the -mm series -- maybe it already has -- but when it's there
you ought to be able to apply this patch to hci_usb.c and make similar
changes to your other drivers.
