Sender: linux-media-owner@vger.kernel.org

Hi,


I bought a TerraTec Cinergy T Stick Dual RC[1] which is not supported in 
linux, AFAIK. The USB VID:PID is 0ccd:0099.

I didn't find much about it with google, so I opened it up. There are 
five chips inside: AF9013-N1, AF9015A-N1, 2x MXL5007T and FM24C02 eeprom.

I'm not a kernel developer but I tried to add the correct USB PID to the 
af9015 driver and modified it to attach the mxl5007t tuner (by following 
the procedure in DiB0700 driver).

The DiB0700 driver uses 0x60 i2c address for MXL5007t tuner but I got 
replies only from addresses 0x38, 0x39, 0xa0, 0xa1, 0xc0, and 0xc1 and 
all with unknown chip id, so I'm probably doing it wrong.

Below is the kernel output when I plugin the USB DVB stick. It seems to 
find the two tuners and tries to use the same i2c address for both as 
I've hardcoded that in the attach function call.
