I managed to download the media-build source code off bitbucket and compile it against the most recent Ubuntu 16.04 kernel (4.15.0-45). My DVB-S2 device is now working correctly on an Intel Atom Media PC, which is great. Thanks very much to crazycat,@CvH and anyone else who helped get the device working.
Just for the sake of completeness, I double checked the LibreELEC build I reported on in my last post. The build seems to match the one uploaded to Index of /test/ds3103b/. The kernel log also confirmed modules were being added from the 'kernel-overlays/driver.dvb.crazycat' folder. As before, I couldn't get the device to load.
After reading your rather promising post, I tried it myself to get my S4600 from 2014 running again. It used to work, until last week before a kernel update.
So I set out and compiled the media-build source into my Ubuntu 16.04 kernel 4.15.0-45 but with no success.
Interesting part is, Chip ID is declared unknown. Before I applied the patches from crazycat, the Chip ID was 23, but it still would not work.
I'm about to try to revert back to a really old kernel, just to see if I can get this dang Technotrend USB box going again.
