I found in ir_common.c a dependencies - bttv module. I supposed it can work with bt cards. But on bt878 I've get only event0 - keyboard, and event1 - mouse - event 2 does not exist. The same kernel shows event 2 for saa7134 correctly (on my machine). Does that mean, that bttv is not supported by evdev? Tuner and radio works correctly.
