    I recently installed a Sabrent 4-Port USB 3.0 Hub (HB-UM43) which I assume should show up in device manager as a bus powered hub since it has no external power supply. It is listed as having a 900 mA draw and is currently powering a pair of 500 mA USB 3.0 flash drives and is recognized as a self powered generic hub in device manager.

    I have spent many hours searching the internet trying to understand how it could be that a non-powered USB hub can show up as a self powered hub in device manager without any answers and I am hoping that I can find an explanation here.
