The attached patch should be better (sorry it's bzipped, but thunderbird
crashed three times when I tried to attach it raw), since it initializes
the remote before calling usb_register.
Could you give it a try?

What I don't know is, if usb_register fails (so making module_init
fail), will module_exit be called nevertheless?
If not, those symbols would be kept and should be freed in module_init
in case usb_register fails.

Bye
