Starting with USB host connected to BBB

Hi,

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…

thanks

Common ground is good.
