I've got a rather exotic piece of hardware:
It's a dipix capture card ( very cool, it's got a TI C40 DSP chip on it,
maybe I could get that thing checking rc5 keys too. )
Anyhow, the people at dipix were kind enough to write a driver for it for
linux. I insert it into the running kernel: ( config follows ), and it's
happy. The fun thing, is it worked under 2.0.33, but if I try and use it
under 2.1.89, I get the kernel pukes on me.
Any and all help is appreciated. I've tried to provide as much info as
possible.
