Well, I've got it working. I think the key was one of these three things: 1) plugging the scanner's usb cable into a hub, and then plugging it into the host controller 2) using "insmod uhci" instead of "insmod usb-uhci" or vice versa. 3) running "scanimage -T" once before running "scanimage > image.pnm" Oddly enough, my home computer and work computer differ on whether the scanner will work when plugged in through a hub or not. The lesson for me is this: USB, while a great technology, is far from mature both in terms of the hardware and linux drivers. What should work in all combinations of host controller drivers, and hub/host-controller interconnects, may only work in certain combinations. So before throwing your hands up, try out different variations *for each computer* you are trying to get it to work on. I have to say I am pretty happy with the quality of the scans, although I am more interested in scanning documents than pictures, so perhaps I am easy to please.
