[media] Afatech AF9035 DVB USB driver
AF9035 is integrated DVB USB interface and DVB-T demodulator. Integrated demodulator is AF9033 and its driver is attached runtime as a own module. Driver currently supports only one device, TerraTec Cinergy T Stick [0ccd:0093]. TerraTec Cinergy T Stick is based of Afatech AF9035 + Infineon TUA 9001 silicon tuner.
