I think Tim already pointed you to the solution of your problem. But

libusbscanner sets the permissions of the respective /proc/bus/usb...
file to group write/readable by the scanner group. So if you are in
group scanner, you should be able to access the scanner.

Possible reasons for not working: 
- No hotplug support in kernel
- scanner not listed in libsane.usermap
- someone has changed libusbscanner
