The internal webcam cannot be detected on some Panther Point-based laptops.
On the Panther Point hardware, some USB ports can be switched to be controlled
by the EHCI or XHCI controller and each can selected to enable SuperSpeed or not.
The patch add more check code so that only the switchable ports (BIOS can set this)
I tested on two HP Pavilion laptops, and the webcam works with the patch.
The patch is just sent upstream. But there is need to get it into Precise soon,
so I sent the SRU at the moment.
It will be good if we can have the patch in Quantal.
