SANE scanner access from inside a VM?

I'm using Arch inside VMware, and trying to connect to a Canon P-208 scanner. I know this scanner to be supported, it has an entry in /etc/sane.d/canon_dr.conf, but it shows up as: $ scanimage -L device `v41:/dev/video0' is a Noname VMware Virtual USB Video Device virtual device and then doesn't work: $ scanimage --device "v41:/dev/video0" --format=png > test.png scanimage: open of device v41:/dev/video0 failed: Invalid argument $ scanimage --test scanimage: sane_start: Invalid argument Is there some way I can tell SANE to treat v41:/dev/video0 as a P-208?
