scanimage seems to have a few bugs, of which I just recently noticed
scanimage does not appear to reset the device after failure or during

or later.  If you're scanning any thing other than black and white
documents, such as photographs or negatives, you'll likely find the USB
method much faster.  As I vaguely recall now from 10+ years ago, the
scanning was extremely slow using 100mbit.  Hopefully you have
