USB 3.0 port troubles are all over the web. Since this is so well done and the reasons for this appear to be the choice of the USB controller, you may want to exchange this for another model that works.

Hi,
i have a HP ultrabook folio 9470m with two regular 3.0 usb ports on the right side of the machine and one powered 3.0 port on the left side.
the powered port does not recognize any device i plug into it.
for example: i have a logitech wireless mouse that works perfectly in one of the two ports located on the right side but as soon as i plug it into the powered port, i get an error message saying unknown device. the issue is the same with an external hard drive and a usb sound card. right side ports recognize it fine, left powered port has no clue what it is. the port is not dead because it sees that something is plugged it, it just doesn't know what to do with it.
i tried uninstalling all of the usb drivers in the device manager to no avail.
please help.
