KB: Using bus powered USB peripherals with the pinephone keyboard mounted
source (pinephone (pro) keyboard):

short version:
do not connect anything to the pinephone usb type-c port, when keyboard case is mounted. regardless does it draw power or insert power.

problem seems to be that pp's usb port is controlled by hardware chip, which seems to be more or less buggy. and that hardware chip starts to insert 5 volts when usb devices are connected, thus resulting dual power supply issue. maybe software can be fixed but hardware overrides are usually not possible.

this or these issues should re-thought in next pinephone.
