Public bug reported:
as reported here: https://askubuntu.com/q/880880/80483
simple-scan sees the USB-powered scanner (CanoScan LiDE 110) but
sometimes fails to start it up.
Usually it scans the first page in several "tries", i.e., the "scanning
noise" comes out in bursts, interrupted by short pauses, and then scans
the page. The second and further pages are scanned in a single burst of
"scanning noise".
However, sometimes, I get a very short burst of noise and then an error
message. When I connect the scanner to a mac laptop, it pauses with the
"warming up the scanner" message and then scans the page. When I
immediately re-connect the scanner to Ubuntu, simple-scan works just
fine.
Is there a way to teach simple-scan to "try harder" when warming up the
scanner?
Changing cables and USB ports does not help.
Sometimes pluging the scanner into the usb2 socket and leave it alone
for a few minutes helps...
