This is not looking good: I compared the two boards and checked the voltages on the USB +5v switch. Both boards use the same parts: Both SS switches have exactly the same voltages applied to the inputs. Pin: 1: USB V-out 0v on V2 (+4.8 on V1) 2: GND 3: Fault 3.27v Active low. 4: Enable 3.27v 5: 5v in 4.8v Output is connected correctly to USB socket, no shorts. Again Both V2 boards are the same.
