I've just rebooted system and printer (both powered off) and discovered this if i run "/usr/lib/cups/backend/usb" lots of times it always gives back the correct information (comment #75) but as soon as i run "lsusb -v -d 04e8:329f" once and then run "/usr/lib/cups/backend/usb", it then fails (as per comment #79).

I tested this twice with rebooting because at first i thought it was a coincidence.

Probably not. Your device appears to have a buggy firmware, which doesn't allow certain descriptors to be retrieved twice (Windows doesn't do that. lsusb or its equivalent do so) -- You are receiving this mail because: You are on the CC list for the bug.
