Yes, it only has bulk endpoints. But I'm not sure if a user level
application is a real alternative to having a "real" driver, which fits
into the dvb api. Since devices are so different in programming this
wouldn't make too much sense, would it?

Yes, indeed, this is a point. But then it won't work with standard
applications (mplayer, xine, scan)...
