Not in any case.
There are several other USB devices which are correctly not
shown as scanners by sane-find-scanner.
Right now I didn't check check_usb_file and the functions
which it calls in detail but according to
it seems sane-find-scanner lists any USB device as scanner when
either bDeviceClass = 255 (Vendor Specific Class)
or bDeviceClass = 0 (Defined at Interface level)
and bInterfaceClass = 255 (Vendor Specific Class)
because those USB devices are "The Usual Suspects" ;-)
