I’ve been trying to use the Waveshare USB Hub hats (with and without ethernet) - that connect to the RPi Zero WH via a small U-shaped micro-USB link - with my BPI-M2 Zero. Power is supplied but the Hub is not detected, nor is anything that is connected to the hub.
If I connect a generic USB-OTG adapter to the BPI-M2 Zero micro-USB port and connect the Waveshare hub with a standard USB lead, everything works well.
Does this mean the micro-USB port on the BPI-M2 Zero is actually different from the one on the RPi Zero WH ?
