Today, I compiled sane-backends-1.0.12 with libusb-0.1.7. After starting the scanner, I did a 'rmmod scanner' to delete the kernel driver, started xsane and did about 12 scans with resizing/rearranging the scanning area: no stop, no freeze, works perfect. So, in addition to switch-off 'quality calibration' for usb connection, it is also important to use libusb instead of the kernel driver (kernel 2-4-19). Cheers, Klaus
