So seeing that it works on 10.11 (but not on 10.12 and 10.13, yet?),
I'll add it to the epson2.desc (and epson2_usb.c) file.

BTW, you are adding the USB info to your epson2.conf (or epson2_usb.c),
aren't you?  You probably also need to do something to get read/write
access to the device when the OS first sees it (or try with root
privileges).  Don't know what you did on 10.11 but maybe things have
changed for 10.12 and 10.13 in that area.

Hope this helps,
