I was wrong about USB, it doesn't work either. The IDE drive failed with a non-packet formatted disc, so I didn't bother to check what was inserted in the USB drive. It turned out it was empty and in that case the driver doesn't hang. Anyway, the problem is that the add-struct-request-end_io-callback patch forgot to update pktcdvd.c. This patch fixes it.
