Xaio 5v and USB simultaneous power

Anyone know if the Xaio can be powered by 5v pin and USB at the same time? I’m afraid to attempt it, I dont want to fry out one of my pc USB ports, or the Xaio trying it.

Hi @brianinoshkosh ,
I checked the schematic.(link)
I think it work to add diode between 5V power supply and 5V pin.
(But I didn’t try that.)
