This seems like overkill for a kernel driver to me. You are probably right. It indeed should be possible to do this in userspace. I thought that having a kernel driver would still be benefical since it adds plug-and-play availability for all Linux users without having to deal with userspace driver programs. You are far more experienced with these things than me, so I am happy to let you make the decision about whether to have a kernel driver or not. -- Lauri Niskanen
