I found the problem. It seems to be a permissions error! man sane-usb This is a short HOWTO-like section. For the full details, read the fol‐ lowing sections. The goal of this section is to get the scanner detected by sane-find-scanner(1). Run sane-find-scanner. If it lists your scanner with the correct vendor and product ids, you are done. See section SANE ISSUES for details on how to go on. sane-find-scanner doesn't list your scanner? Does it work as root? If yes, there is a permission issue. See the LIBUSB section for details. Nothing is found even as root? Check that your kernel supports USB and that libusb is installed (see section LIBUSB). LIBUSB SANE can only use libusb 0.1.6 or newer. It needs to be installed at build-time. Modern Linux distributions and other operating systems come with libusb. Libusb can only access your scanner if it's not claimed by the kernel scanner driver. If you want to use libusb, unload the kernel driver (e.g. rmmod scanner under Linux) or disable the driver when compiling a new kernel. For Linux, your kernel needs support for the USB filesystem (usbfs). For kernels older than 2.4.19, replace "usbfs" with "usbdevfs" because the name has changed. This filesystem must be mounted. That's done automatically at boot time, if /etc/fstab contains a line like this: none /proc/bus/usb usbfs defaults 0 0 The permissions for the device files used by libusb must be adjusted for user access. Otherwise only root can use SANE devices. For Linux, the devices are located in /proc/bus/usb/ or in /dev/bus/usb, if you use udev. There are directories named e.g. "001" (the bus name) con‐ taining files "001", "002" etc. (the device files). The right device files can be found out by running scanimage -L as root. Setting permis‐ sions with "chmod" is not permanent, however. They will be reset after reboot or replugging the scanner. Okay, do I need to make it look like: none /proc/bus/usb usbfs defaults 6 6 or what do I need to do?
