Please help with adding Support for 1b80:d393 Afatech DVB-T receiver [RTL2832U]

[GeoKM]

Hi I am trying to get a couple of these USB DVB-T Tuner sticks working under Mythbuntu 12.04.
They are Gigabyte U7300 Model USB 2.0 devices and they appear in lsusb as

1b80:d393 Afatech DVB-T receiver [RTL2832U]

I am wondering if I can help you to add support for these in your module.

My current Kernel is 3.2.0-24-generic #37-Ubuntu SMP Wed Apr 25 08:43:22 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

I cloned your repository and built the module all ok and it load without a problem, however in dmesg it complains that no fronted was attatched.

I guess the module does not know about this particular tuner?

BTW I am in Australia.

dmesg from immediately after boot output is as follows

[ 139.584406] RTL2832U check_tuner_type : ERROR Unknown tuner on board...

removing the module and reloading it with sudo modprobe dvb_usb_rtl2832u debug=1 shows
