Can someone confirm that only one USB port can be connected to external powered USB hub?
I am unable to use wireless USB keyboard / mouse connected to D-link USB hub UNLESS the hub is connected to specific port on Pi. Sorry- I do not know how they count, so I cannot provide better info.
I would like to record ( print) the USB error messages when the port cannot be activated. Is there a way to do that? The printout disappears after the PC runs.
