Once the module is built and installed, the cx231xx module should autoload on detecting the device. So it should be supported in kernel 3.10 and later.įor earlier kernels, we need to add the device definition and some related details to the cx231xx driver and have installed the appropriate firmware (see below). īack: Mygica EZGrabber2 (top) & Diamond VC500Ī patch for this device has been accepted into to the 3.10 kernel.

However examining the Windows drivers provided by the vendors, they refer to the device Polaris.CVBS or POLARIS.OTG102, and contain many of the same driver files as other devices containing the cx2 chips. However the indication that it can output compressed MPEG-4 video does suggest that it is not a standard cx2. There is no reference to this chip on Conexant's website nor practically the entire internet, so likely this is just a renumbered chip for these specific vendors. The single chip on the board is labeled as CX78921-11z. It has the standard USB 2.0 interface with stereo, composite video and S-Video inputs. On Linux, using a patched cx231xx driver, it is at least possible to get uncompressed YUV4:2:2 video and 48000Hz stereo through the corresponding alsa device. Supposedly supports output of compressed MPEG-1/2/4 streams (on Windows).
