Hi, here are some things to try/clarify: - when using scanimage, the default scansize is 126x76 mm - try using libusb even on 2.4.2x kernels I don't think that the scanner module is a good idea. - use libusb-0.1.8 or 0.1.10 - 0.1.9 seems to be buggy - disable all the backends but plustek - for getting debug information from the plustek backend, try: export SANE_DEBUG_PLUSTEK=20 I'm pretty sure, that this is a USB problem and not backend related.
