I get an oops on shutdown with 2.4.20 (speedtouch driver).  Here is what
happens:

probe method called: I take a reference to the usb device with usb_inc_dev_use

(machine shutting down - shutdown of usb subsystem)

disconnect called

(still have the reference)

If you still hold it after your disconnect() returned, the bug is in your driver ...


...time passes...

final driver shutdown: I drop the reference using usb_dec_dev_use, which oopses.
