This detection is based on the `bcdDevice` field, but it's unlikely that
this is a GL128 scanner; purportedly the Plustek 8100 is a slight
modification of the 7400-v2, which is based on the GL843.

re: genesys.conf, unfortunately the Genesys driver has (and requires) an
extensive table of details for every scanner model, and `genesys.conf`
only serves as a list of devices to _try_ probing. If a corresponding
entry doesn't exist in genesys' compiled-in table of scanners, it still
won't recognize it as supported.

To this point, if you're familiar and comfortable with compiling code,
you could add your scanner to the supported list and recompile SANE and
see if it works. You should be aware however that the worst-case failure
mode here is physical damage to the scanner, if the driver manages to
instruct it to run its motors in a way that causes damage. (These
devices have surprisingly little safeguards built-in.)
