You can install drivers and all the stuff needed to support the device, but it will not work if the receiver does not know what the device is or what it is supposed to do! I suspect this may be the problem.
Here is one reason why the driver is listed in enigma2 feeds, but does not work:
There has not been any interest in ATSC enigma2. No one in North America has shown much of a desire to test anything or to make any improvements in enigma2. ATSC works well for me with the 850 and that is all that matters! Lol. I will see if we can get the help that is needed to make the 955 work if you are interested.
