Are you sure only root has permission? Is there group read/write
permission for the group "scanner"?

My USB scanner is appearing with group scanner write privs.

If the device is not set to group scanner, have a look in
/etc/hotplug/usb/libsane.usermap. The comments at the top of this file
describe how the scanner permissions should be managed.
