		+	As of 11/28/2012, the cx231xx driver in 3.6 kernel probably works fine with this device. At least the same config as is present in the driver fot the Hauppauge USB-Live-2 has been found to work fine with a Elgato Video Capture V2 board, which uses the same CX 23102 chip and has very similar lsusb output.

==Attempts to make it Work==
This section will be a bit non-wiki like but hopefully someone will find it useful.

There is a driver in kernel for the cx231xx series chips. Currently there are only board definitions for some reference designs. I added a new board definition for this board with as much information I could trace on from PCB. The driver begins to load but starts spitting out lots of errors pertaining to communication issues.

I managed to get it to the point that the driver loaded and attempted to initialize the board but I was getting intermittent EPIPE errors that caused initialization to fail. To get that far I had to comment out a bunch of the drivers attempts to initialize an external tuner (which this card doesn't have). The board def was set to TUNER_ABSENT however in many places it doesn't appear that there was a check to see if a tuner is there before calling some of the I2C functions to talk to it. Tracing the loading process there also appeared to be sections stubbed out that would be needed for this card's arrangement. I don't have any previous experience with these types of chips and was unable to find a full datasheet for the Conexant chip so am at a road block in trying to get it working alone.

It would appear in general that the cx231xx driver is in a bit of a skeleton state and only was developed to work on the reference designs.
