In case somebody might have similar issue and settings: I found rndis as solution for any useable inet access at least. Docu here: http://docs.ubports.com/en/latest/userguide/advanceduse/reverse-tethering.html I had to set link up and give address manually. But jippie, it works. (WiFi stopped working. Was not able to get it working again.) I got inet connection on the phone, but it seems to not use this connection for "fetching channels" - wheel's turning, no traffic seen via tcpdump on the rndis interface of the pc. Still: Some image/packages to download would still be great.
