I am powering the Rock Pi through the USB C port. I need to control it through ADB from PC but there must be also USB devices connected to the Rock Pi. This means, I cannot switch it to device mode but the USB C (OTG) port is occupied by the power cable.
Connecting the Rock Pi with the USB C (OTG) port to the PC is no option as well because the USB A (3.0) ports of the PC do not provide enough power.
So what is the option to provide enough power, have an ADB connection to a PC and at the same time some USB devices on the USB A ports of the Rock Pi 4?
