Hi Guys,
Bought this card as it is supposed to be recognised by the kernel but there were a few caveats. The card is recognised as the conexant CX23885 but the firmware needs compiling to work properly with this tuner.
I have got it working and have added a script to compile the firmware on the wiki page.

Now fully working DVB-S2 twin tuner. Very pleased.

Thanks for the wiki page. Be careful with new kernels, and remember to recompile the driver for it. Or, make life easier for you, and make it a dkms driver ;)
