I installed the drivers for a Canon Pixma TS9100.
It prints fine, but xsane can not see the scanner. Same with simple scan.

sane-find-scanner will now attempt to detect your scanner. If the
result is different from what you expected, first make sure your
scanner is powered up and properly connected to your computer.
No SCSI scanners found. If you expected something different, make sure that
you have loaded a kernel SCSI driver for your SCSI adapter.
found USB scanner (vendor=0x04a9 [Canon], product=0x1820 [TS9100 series]) at libusb:002:003
Your USB scanner was (probably) detected. It may or may not be supported by
SANE. Try scanimage -L and read the backend's manpage.
Not checking for parallel port scanners.
Most Scanners connected to the parallel port or other proprietary ports
can't be detected by this program.
Sane found the right printer?
