I've tried to use the scanner of my Lexmark X73 without success. As I have a kernel v2.6 installed, I must use libusb, not a kernel module. The problem is, sane-find-scanner seems to detect it quite well, according to this:
# No SCSI scanners found. If you expected something different, make sure that
# you have loaded a SCSI driver for your SCSI adapter.
found USB scanner (vendor=0x043d, product=0x002d, chip=GT-6816) at libusb:001:007
# Your USB scanner was (probably) detected. It may or may not be supported by
# SANE. Try scanimage -L and read the backend's manpage.
# Not checking for parallel port scanners.
# Most Scanners connected to the parallel port or other proprietary ports
# can't be detected by this program.
# You may want to run this program as root to find all devices. Once you
# found the scanner devices, be sure to adjust access permissions as
Unfortunately, scanimage tells me it has found no scanner at all (and so does xsane). I've the latest versions of sane-backends and libusb installed, gt68xx is enabled and oslo3071b2.usb is at the right place.
Does somebody have a clue?
