Hello Rudy
I use a similar card from Digital Devices with Ubuntu 14.04 and kernel 3.13.0-32-generic. Support for this card was not build into the kernel and I had to compile it myself. I had to use media_build_experimental from Mr. Endriss.

Your card should be supported with this version.

Hi Rudy,
What Thomas writes is absolutely correct...
This is unfortunately the worst situation I've ever run across in
Linux... There was a kernel driver that worked and was supported by
Digital Devices. Then, from what I read, changes to how the V4L drivers
have to be written was changed - Digital Devices doesn't like that and
they force users to use "experimental" builds which are the "old
style".
This is total rubbish imo - if this is how it was decided that the
drivers have to be nowadays then adjust them. Why am I paying such a lot
of money others right, these DD cards are really not cheap?
Some attempts have been made by people active here to adapt the drivers
and make them work in newer kernels, but so far no one has succeeded.
Last attempt was in Jan 2014 iirc, since then - silence.
I wish I could help out, I can code but Linux is well just a bit more
"difficult" I guess ;-)
I have one of such device too, but I have been too busy all the time
with other drivers...
Basically these DTV drivers should be developed in a order, bridge
driver first, then demod and tuner - for one single device. After it is
committed in tree, you could start adding new devices and drivers. If
you try implement too big bunch of things as a once, you will likely
fail endless reviews and so.
I don't know what is change in development process which causes these
problems. What I remember there has been only few big changes in recent
years, change from Mercurial to Git and reorganization of directories/files.
regards
Antti
