For the snapscan backend that's currently not possible, as there is
only a single firmware file entry in snapscan.conf. Eventually I'd
like to change this to a single directory entry and a filename entry
for each USB scanner (e.g. after the corresponding USB ID entry in

Not really, at least for the snapscan backend. Benq uses the version
number of the firmware as part of the filename, so either the files
would have to be renamed or the backend would have to do some
wildcard matching. I prefer to list the most common name in
snapscan.conf where it can be changed if needed.

I'd like that as well. It would also be nice to link to the firmware
files from the snapscan page or the SANE page of supported scanners -
unfortunately I've never received a single answer from Acer/Benq to
any of my emails.
