TLDR: are there any known issues using a Nikon Coolscan IV ED with
libusb 0.1.12-30 and kernel 4.9.0?
---------------------------------------
I'm trying to get an Coolscan IV ED (LS40) to work with Debian Stretch
(current stable release).
scanimage -L
properly identifies the scanner, however
scanimage > testme.pnm
hangs and eventually errors out due to an i/o error.
I connected this scanner to a laptop running the same software with the
same results.
I connected the scanner to an older laptop running Debian Jessie
(previous stable release), and it works fine, and I can also pass along
additional command line arguments for white balance, auto-focus, etc.
I'm guessing something may have changed in libusb and/or the kernel,
which is preventing communication with this older USB1.1 unit.
Are there any known issues with this setup?
