USB DVB not working and power consumption - Odroid C2

Troubleshooting
1

I have a USB DVB-S2 tuner connected to a Odroid C2
It shows up here:

~$ lsusb
Bus 001 Device 003: ID 0572:6831 Conexant Systems (Rockwell), Inc. DVBSky S960 DVB-S2 tuner
Bus 001 Device 002: ID 05e3:0610 Genesys Logic, Inc. 4-port hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

But

dmesg | grep -i dvb

shows nothing?

In Armbian it works right away.

I also realized that DietPi draws 1.2 Watt more (3 vs 1.8 ) from the socket then Armbian.
I already set DietPi to headless and in Armbian HDMI is on…
Whats the reason for this?
