My USB Canon CanoScan LIDE N650U is not getting recognized, except in lsusb.

For some reason my scanner stopped working after i changed system and kernel

I cannot use a newer kernel than this 2.6.22.1 or my ati drivers will
not work. the kernel is custom compiled from kernel.org and has ehci,uhci,ohci
compiled in as modules and also usb devfs enabled

mws:/home/michael# mount -t usbfs
procbususb on /proc/bus/usb type usbfs (rw)

when starting xsane as normal user in group 'scanner' it just opens /dev/video0 instead , which my my webcam
I tried removing the webcam from the usb hub without luck.

Nothing in dmesg:
udevd version 125 started
usb 1-4.2: new full speed USB device using ehci_hcd and address 36
usb 1-4.2: configuration #1 chosen from 1 choice
usb 1-4.2: USB disconnect, address 36
usb 1-4.2: new full speed USB device using ehci_hcd and address 37
usb 1-4.2: configuration #1 chosen from 1 choice
usb 1-4.2: USB disconnect, address 37
usb 1-4.2: new full speed USB device using ehci_hcd and address 38
usb 1-4.2: configuration #1 chosen from 1 choice


I have tried opening the device files that udev makes (with xsane /dev/usbdev<xxxx>)
 but i just get invalid argument, here is udev debug output (directly after insert of usbcable into scanner):

Lsusb finds the scanner without problems..

Any idea what I am missing , I thought usb scanneres were using libusb nowadays
 so it should be autodetection ?:)
