Thank > you! :) I'm not an expert in writing kernel modules too :) But, imho, writing the simple character device driver is not too hard. Now I have similar problem - I need to control MasterVideo's 4-port bt878 card, and I need to access bt878's i2c and gpio from userspace in some way. I will looking at this and may be I'll write appropriate driver (or modify bttv driver). So, if you are not under time pressure, stay tuned ;) -- Andrey Vasilyev
