A little update...

I now have one of these devices. The chip is actually a M8BRS2000 which
is a combi frontend/tuner device.

The ID is confirmed as 3344:22f0, it appears to be patched by the
Windows Driver as 3344:1120 devices try wrongly to use the RS2000
driver.

There is no Linux frontend driver for this device. I will start to write
one shortly, so support could be several months away.

Malcolm
