I just would like to know, if there would be any problem with startups if the BBB would be powered up with a +5V adapter, and some USB devices like USB pen drive, USB-Serial converters connected to the BBB via an externally powered USB hub ??
The BBB is connected to an external +5V adapter. and the USB hub powered through another adapter but with common grounds…
Do you think the common grounds would cause some problem ??
Sorry if this sounds stupid…
