I also bought that stick recently and I've started to "work" on the Linux 
support. The only problem is that I don't have much module programming 
experience and neither much knowledge of DVB-T hardware...

So far, I've managed to find identify the USB commands for the remote control 
(and the led). I think that I've also identified some kind of firmware 
(actually 2 different ones) that are loaded once the stick is plugged in (in 
Windows of course).

Basically, I'll try to follow the example of the em28xx module, which seems to 
have similar capabilities to the tm6000. The demodulator seems to be the 
ZL10353 in our case, but I haven't managed to identify the remaining chips. 
If you dare, could you open the stick and look what's really inside ? :-)

Ok, that's it for now. I'll play a little bit more with the device in the next 
days and hopefully discover some more interesting things.
