The Linux kernel scanner driver also knows the vendor and product ids (version 2.4.12 and later). So I'd either add just "usb" to epson.conf and let the backend do the rest or add "usb vendor product" lines for all supported scanners to epson.conf. If the user doesn't use libusb and uses an old (or non-Linux) kernel scanner driver he can still place the device file name in epson.conf manually. The question came to my mind because I read about the "usb" automatic stuff in the epson backend but neither epson.conf nor sane-epson.man makes any mention of it. Bye, Henning
