Raspberry PI HVR-850 v1200 DVB driver?

[apokalypz]

I have a Hauppauge HVR-850 v1200 that my raspberry pi 2 won't load DVB drivers for. I originally used it on an odroid XU4 and it worked flawlessly, however, plugging it into my raspberry pi only shows the analog part of the adaptor.

Inspection of the Raspberry Pi 2 kernel messages revealed:

It seems that the raspberry pi 2 isn't detecting the TDA18271HD/C2 correctly, instead it is seen as an "unsupported device". So I'm guessing a change in the drivers sometime between the XU4 kernel and the much more recent Raspberry Pi 2 kernel broke it? Does anyone know of a fix/workaround? Thank you.

You may have to make a line entry in the modules.alias file for your device, to make sure the correct driver is loaded. Exact path to that file will depend on your kernel - probably in /usr/lib/modules

If you have the exact name of the driver that worked in another system for the device, you can check that file to see if the driver has already been installed on your Pi and is simply not recognizing your device.

The difference here is the problem. It seems that the device is getting detected as unsupported on Pi2's kernel as opposed to the state of the XU4. Both kernels have the necessary module configured as a module (CONFIG_DVB_TDA18271C2DD=m), and the only slight difference is CONFIG_MEDIA_TUNER_TDA18271=m vs =y on XU4. This still doesn't quite seem like it is the fault of the kernel config.

Ensure that the Pi2 is fully up to date, and that the kernel running matches the installed package.

[apokalypz]

It is fully updated and running the latest kernel.

I tried sifting through the source code and it's a bit beyond my skill level. Maybe I'll try doing a diff between the XU3/4 source files and the RPI source files and see if anything sticks out.
