Copy/paste from the Amlogic forum:
Hi guys,
I'm running version 8.90.3 on my S912 device and tried an Hauppauge DVB stick that I had lying around. It seems to recognize it but I can't see it in tvheadend under adapters. I installed the Hauppauge drivers addon.
Here is my system log: Fqn
Edit: I'm using a minix u9
