Someone suggested, off-list, trying a newer version of SANE.
I've now been able to try 1.0.27, on a different machine running a
different OS (Ubuntu 18.04) with a different USB cable, and got the
same result: the scanner's motor does not run, and it generates an
all-gray image file.
Using a different machine and cable seems to exclude most possible
hardware-related issues other than the scanner itself, but I suppose
it's possible that the firmware file I'm using could be corrupted.
Does anyone have a Plustek M12 working, and if so could you post a
hash (MD5, SHA1, whatever) of the cism216.fw file?
