Ah, thanks for the report, seems I didn't even test this!
So digging around I figured it's working in Linux, and it's the right
USB port, but we are missing the VBUS power switch, which is a GPIO
controlled regulator. There are pending patches to pick this from the
devicetree[1], but we are not there yet, so we need:
CONFIG_USB1_VBUS_PIN="PC16"
in the defconfig, for now. I will update the file. The same is
actually missing from the OrangePi Zero2 defconfig, I will send a patch
ASAP.

Great, thanks for the tag!

Cheers,
