As far as I know noone is working on a driver. > If not, can someone point me towards info on getting it done myself? Find out what protocol is used. There is already a bit information about the chipset in the SANE scanner lists on the SANE website. Get documentation from the maufacturer of the scanner and/or chipset. If you can't get that, find out how the protocol works. Once you know the basic protocol, write a Linux program that reproduces the USB commands. You can make that a backend later. More info is in doc/backend-writing.txt in the sane-backends source code package and here: http://www.meier-geinitz.de/sane/misc/develop.html Please keep us informed. Even if you made only small progress like getting usb logs under windows, place them on a website so others can have a look at them. We'll add a link to them from the SANE scanner lists.
