I did some research and it looks like the B2C0 and B3C0 modell differ only in
packaging. I did receive a haupauge remote with the stick, that is normaly
sold seperatly.
As there is no support for the ir sensor in the stick, I added it ;)
I attach the patch to support the new grey and color remote with the
hauppauge:
Cheers Ben
