DMX_SET_SOURCE seems to not be implemented anywhere, all it does is 
return EINVAL. I also fail to find any useful documentation about what 
it is supposed to do.

I think there is currently no useful API to connect devices. Every few 
months there comes a new device which deprecates how I enumerate devices 
and determine types of FE's.

The most useful way to query devices seems to be using HAL, and I think 
this is the correct way in Linux, but DVB-API may be lacking with 
providing the necessary information. Maybe this is the direction we 
should consider? Device names under /dev seem to be irrelevant nowadays.
