I used to use my Epson scanner, back when I was running Ubuntu 17.04. Since I upgraded to 17.10, though, XSane and Simple Scan just can't find it. It shows up on lsusb, and I've downloaded and installed Epson's drivers, but it's just not working. I know the scanner and usb cable are good; it works fine with my MacBook Air. Can anyone help?
I just upgraded to Ubuntu 17.10 and experienced the very same problem like the op; however, I was able to fix it for me in four steps:

I fear that this is a known bug. See https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1728012
Although they're referring to 18.04 that's the same version of libsane1 as in 17.10 and the change to sane appears to have stopped various Epson scanners from working.
