If there exists a usb.usermap in /etc/hotplug it should be modified due to /usr/share/doc/packages/sane/sane-backends/plustek/Plustek-USB.txt. Last not least the plustek-entry in /etc/sane.d/dll.conf should be uncommented. Additionally you should make sure that the scanner.o module isn't loaded and that possible remnants of the prior sane-installation are removed completely. Regards Wolfram Heider
