[sane-devel] sanei_config_attach_matching_devices() for USB

OK, thanks, that makes sense.

That's true, unfortunately, as I just found out. In that case, my only
suggestion is to have the scanner kernel module create a /proc entry
that shows all recognized scanners, with their filenames. This of
course only works with devfs, because without devfs the module only
knows major/minor numbers, not which device files correspond to these.
