According to the man-pages, this should be solved by adding the folowing rules to /etc/devfs.rules: # Allow any user to access uscanner and ugen devices rw add path 'usb0' mode 0666 add path 'ugen*' mode 0666 add path 'uscanner*' mode 0666 I restarted devfs but the devices were created with the wrong permissions when I plugged in the scanner? If I restart devfs after plugging in the scanner permissions are corrected. But I think this is rather annoying - is this intended? no problem report has been filed on this issue... > > $ sane-find-scanner -q > > found USB scanner (UNKNOWN vendor and product) at device /dev/uscanner0 > > found USB scanner (vendor=3D0x04b8 [EPSON], product=3D0x0121 [EPSON Sca= nner]) at > > libusb:/dev/usb0:/dev/ugen0 > > > [...] > > This is a problem, a USB scanner under FreeBSD should use uscanner(8) > driver nothing else.

OK, I will update usbdevs and uscanner.c and submit a patch if this makes it work. Yet, I still can't understand howcome I can successfully scan an image as root if scanning is only supposed to work with the uscanner device.
