Sounds like we have some problem with the genesys backend. Can you compile an older version of sane-backends (perhaps 1.0.24, or whatever version Ubuntu 14.04 used)? If that works, then you can do a git bisect, and find where it breaks. If that does not work, I think we are looking at something else different in the newer Ubuntu, like libusb or the kernel.
