I have a BBB with a USB Serial plugged to the USB Host (P3). I’m using a 5V power supply connected on P1.
If I disconnect the power supply with the USB Serial still plugged, and connect again, the BBB doesn’t init (the power led does not turn on).
If I unplug the USB Serial, connect the power supply and then plug the USB Serial, everything works.
I tested with 3 different 5V power supplies (1A, 2A and 2,5A), and the result is the same.
Does anybody had the same problem? I looked the schematic and didn’t see anything that prevent the board to start.
