Really appreciate it CvH!
For the next two weeks i'll be offline, as i am on holiday in lovely Italy with the family.
Lets make a plan when i'm back. There might be a chance to load the ngene module with specific parameters to configure the driver correctly for my device, I believe we're not too far off. I've seen the ngene module loading OK (no ngene: Unknown symbol dvb_ringbuffer_write_user (err 0)) but the card still didn't show up, here the messages i've observed full logs attached.
This is from the full ubuntu install (16.04.03)
