It _will_ work with sane without > access to /dev/usb*. It does here. This is an Epson Perfection 1260. Don't ask what the 'Perfection' stands for. Anyway, this is in fact a Plustek, so I have to add the following to /usr/local/etc/sane.d/plustek.conf: -[usb] +[usb] 0x04B8 0x011D +device /dev/uscanner0 I need vendor and product id to get this working. Without getting this info, eg scanimage -L will complain that it couldn't find a scanner, etc. only with /dev/usb* set to root:usb, I will get %scanimage -L device `plustek:/dev/uscanner0' is a Epson Perfection 1260/Photo USB flatbed scanner Regards, Holger Kipp
