It fails to work even with JumpDrive (the computer cannot see it on USB), whereas the new one I just received works just fine with the same JumpDrive image on the same microSD card, the same USB C-A cable and the same computer.
So I will have to resort to WiFi to transfer my data from the broken PinePhone to the new one.
what i have looked the schematics, usb is in a soc chip. although other (physical) components or chips could be the cause as well. not necessarily conclusive, but this increases my feeling that we play some kind lottery game with quality of mainboard and soc chip.
