Hey! I've a question regarding the epsonds backend. I'm trying to get my
scanner working with the latest 1.0.25 release of sane-backends. I got it
to a point where it now finds the scanner once when using
scanimage -L
but after that it doesn't find the scanner ever again until I unplug and
plug it back again (USB).
Here is the debugging output of the scanimage -L command I've used
(https://gist.github.com/walski/7117f69c9e70b1733c6b14c928050ada
<https://gist.github.com/walski/7117f69c9e70b1733c6b14c928050ada>):

The problem seems to appear somewhere around line 17 of the second run when
it seems to send some command to the scanner but receives an unexpected
result :/
Any idea on how to proceed to make this work again?
Thanks so much,
