Bug#289894: EPSON Perfection 610 fails scanning

[rdoursenaud@free.fr]

Package: kernel
Version: 2.6
Severity: normal


Hello,
Everytime I try to scan using this device, the process starts then
hangs. It freezes Xsane. I need to unplug the device to get the error
message.
The problem comes from the USB communication with the device.
I end up with a control timeout on ep0in.
Tried on kernels 2.6.9-2-686-smp, 2.6.10-1-686-smp and a custom built 2.6.9 :
same results.

Here is the relevant part of dmesg :

usb 4-1: new full speed USB device using address 4
usb 4-1: control timeout on ep0in
usb 4-1: control timeout on ep0in
usb 4-1: control timeout on ep0in

If you need more info, please ask.
I'll try later with other kernels and report if I find one that's
working.

Please forgive me for my bad english.
