Status

Mostly working. Things which work include:

  * Device is recognised and two tuners and two demodulators are attached
  * Can play video streams using Kaffeine
  * Remote control initialisation and codes have been determined

Things which may not work include:

  * "scan" only finds some transponders (for Nick Andrew, at least)
  * Have not successfully used dvbstream yet
  * Device is probed twice and so results in 4 adapters: /dev/dvb/adapter0..3 (instead of 2)

To make it work this device needs:

  * m920x experimental tree from mkrufky
  * dvb-usb-tvwalkert.fw firmware file from Nick Andrew
  * tda1004x patch from Hartmut Hackmann
  * m920x patch from Nick Andrew

Technical Details

The M9206 chip handles two demodulators and two tuners.

The demodulators are located at i2c addresses 0x10 and 0x16.

The tuners are located at i2c addresses 0xc0 and 0xc2.

Also, the device is probed twice, so it ends up as 4 adapters: /dev/dvb/adapter0 .. adapter3.
