Hi,

 

According to the suggestions I've modified dvb-usb-ids.h and cxusb.c to add
a support for that card.

 

I would appreciate someone to look at the code below and compare it with
spec on the wiki for that card.

After modprobing cxusb driver I have:

dvb-usb: will pass the complete MPEG2 transport stream to the software
demuxer.

The question is if it is ok or maybe something is missing here and what
should be next steps.
