Из man 7 sane:

   If  your  device  isn't  found  but  you  know  that  it  is  supported,  make  sure  that  it is detected by your operating system. For SCSI and USB scanners, use the
   sane-find-scanner tool (see sane-find-scanner(1) for details). It prints one line for each scanner it has detected and some comments (#).  If  sane-find-scanner  finds
   your  scanner  only  as  root but not as normal user, the permissions for the device files are not adjusted correctly. If the scanner isn't found at all, the operating
   system hasn't detected it and may need some help. Depending on the type of your scanner, read sane-usb(5) or sane-scsi(5).  If your scanner (or other  device)  is  not
   connected over the SCSI bus or USB, read the backend's manual page for details on how to set it up.
