AF9035 with no tuner?

Hello,

I have a USB device which digitizes composite video into a MPEG-2 stream (I think). It is an AF9035 device according to windows. But it has no tuner. Is there a way to make it working on linux or am I out of luck?

Open the device and take pictures of the pcb and the chips. After that it might be possible to identify what kind of device it is.

Hi, seems like this device is a nogo.

No driver support for the composite interface of the af9035. No driver support for the AVF 4910BA1 video digitizer chip.
