TerraTec T6 Dual DVB-T Stick

It consists of
- Afatech AF9035B-N2 USB Interface with included AF9033 Demodulator
- Afatech AF9033B-N2 second Demodulator
- Fitipower FC0012 Tuner (2 off)
This device is currently not officially supported by Linux, however it is possible to get it working using a slightly patched version of the AF9035 driver as used in EzCap_DVB_T_Stick.
Instructions how to get the stick working
Follow the instruction to get the AF903x source code archive AF903x.tar.gz in EzCap_DVB_T_Stick.
I run kernel 3.0.1 and therefore I needed a few patched just to get the source code compiled (you may not need all of them, but they shouldn't hurt either).
