I do not understand how automated firmware upload should work
if there is more than one scanner connected which use the same
backend but which need different firmware files.

Of course a precondition for automated firmware upload is
that the backend knows the directory where the firmware files
are stored - therefore I appreciate the above change.

But my question is:
Can the backend automatically determine the right firmware file
for a particular model?

If yes, it would be great because then it would be possible to
ask the manufacturers to allow re-distribution of their firmware
files "as is" so that all firmware files for all models of a
backend could be stored in the same firmware directory
and the backend would pick the right one for a particular model.


Kind Regards
