CEC Pi zero

Faking HDMI Port

echo "pa 30 00" | cec-client

sets physical address to 3.0.0.0 - which is HDMI Port 3 - receiving remote control signals from different hdmi port

Use Pi zero as "Pulse8 CEC Adapter"

Enable USB Serial

/boot/config.txt add dtoverlay=dwc2 /boot/cmdline.txt add modules-load=dwc2 (not dwc2,g_serial - see below)
