For the people using the new VU+ Turbo SE Combo DVB-C/T2 Hybrid USB Tuner, it works perfectly on my VU+ Zero 4K for DVB-C service.
After installation of following driver from the OpenPli 7.3 plugin feed the tuner is correctly recognized:
ct2-usb-dvbsky-t330 (1.0-r0.0)

I only experienced in some cases the box completely hanging when zapping from satellite tuner to DVB-C tuner while oscam was running, even with FTA channels.
Only remedy was rebooting the box (E2 restart didn't help/work).
After some heavy troubleshooting I got rid of this problem simply by changing PMT Mode 6 to 0 in oscam.dvbapi.
Since then the tuner is running very stable, no glitches, freezes or whatsoever.
