I am running power to my Nano through the barrel jack, shorting the pins on J48 with a jumper.
I theory this would let me use the Micro-USB for data, as indicated for item (3) in
However, I get nothing at all in the following configurations from that port
(1) plugging in any single device in the MicroUSB
(2) I can measure no 5V on the microUSB jack
(3) I cannot run anything when plugged in any device through a powered hub attached to the MicroUSB port
In all cases “lsusb” does not give me any indication that the device plugged in is seen at all
(including a mouse, keyboard, and a USB-serial converter – they all work on the USB3 ports)
Other than shorting the pins of J48 do I need to do anything else to enable the Micro-USB port?
