Bonjour,

At the early beginning of kernel boot, I can read this message:

USB 3-1 device descriptor read/64 error -71
(repeated four times)
USB 3-1 device not accepting address 5 error -71


and... my scanner no longer works....

What can I do?

kernel 2.6.20-1.2948.fc6 (x86_64)

Thanks for any clue.
