This looks like the problem that many are having with Plustek scanners. Are you using a new kernel? Is your kernel built with CONFIG_USB_SUSPEND? If you are using Debian sid then recent kernels certainly are, and the same goes for recent Ubuntu kernels. This requires a fix in libusb (which is not yet available). The only guaranteed cure is to turn off CONFIG_USB_SUSPEND (or use a kernel before it was introduced), but if you can get a parameter to the usbcore module (it can be specifed on the linux command line from Lilo or Grub) set usbcore.autosuspend=0 and this might help.
