Hi, I just subscribed to this list.
After asking C-Channel multiple times for a linux driver for their PayPen family of devices, I decided to buy a cheap one from eBay and see what I can do myself. The USB ID was recognized, but that was about it. Bus 002 Device 010: ID 0a93:0002 C Technologies AB C-Pen 10 This is how it looks: http://www.wetter.ch/portrait/files/468/00020992-mypen_20.3.03.jpg Searching on the internet I found out that there are similar devices, but none of them seems to be really supported on linux. http://lists.alioth.debian.org/pipermail/sane-devel/2009-February/024028.html http://www.sane-project.org/unsupported/c-channel-mypen-pro.html Now if I want to give it a try developing a driver, how should I proceed?
