Using SANE_DEFAULT_DEVICE makes only sense if several devices are available and one shall be selected. The device name is wrong anyway (compare it to the one given by sane-find-scanner). Most probably the correct one is: plustek:libusb:/dev/usb0:/dev/ugen0 Just running "scanimage -L" without any defaoult device should print the full device name. > scanimage: open of device plustek:/dev/ugen0 failed: Error during device I/O Wrong device. If the scanner isn't found without setting SANE_DEFAULT_DEVICE, provide a log file (SANE_DEBUG_PLUSTEK=255). Bye, Henning
