With my Canon Canoscan N650U, I've just given a try with the Gutsy Tribe 2 burned as a live CD.

I first booted on the live CD, plugged in the scanner, then started xsane from the Applications menu.
The scanner was recognized, but trying a preview scan hunged xsane.
Same behavior as in Feisty (I use scanbuttond on Feisty to have it working fine).

So I disconnected the scanner, rebooted the live CD, then run a terminal, logged into root and keyed in the command to stop autosuspend :

$ sudo -i
# echo -1 > /sys/module/usbcore/parameters/autosuspend

Then, I plugged in the scanner, and started xsane from Applications menu.

At that point, I was able to fully use the scanner, it was working fine.

Whatever the status of this bug in Gutsy, it looks like running this scanner type in Gutsy will be possible with USB autosuspend off, a simple option added into Grub's config file to disable autosuspend at boot time should do the trick.
