LinuxQuestions.org - scanner not detected

I'm having trouble detecting my scanner (CanoScan FB 320P).

According to the sane documentation this scanner is supported by xsane and its backend can be edited in canon_pp.conf.
However, when trying to detect it, i get nothing.

Code:

[root@localhost jeremie]# sane-find-scanner



  # No SCSI scanners found. If you expected something different, make sure that

  # you have loaded a SCSI driver for your SCSI adapter.



  # No USB scanners found. If you expected something different, make sure that

  # you have loaded a driver for your USB host controller and have installed a

  # kernel scanner module.



  # Not checking for parallel port scanners.



  # Most Scanners connected to the parallel port or other proprietary ports

  # can't be detected by this program.

Code:

[root@localhost jeremie]# sane-find-scanner -v
