That is the USB 3.0 Host Controller. A lot of folks are having trouble with USB 3.0 in Windows 8. You must have a fairly recent laptop but to help much more I need to know your model number and also it would not hurt to go into the advanced properties of the offending device and give us the hardware id string so we can see what type of USB 3.0 controller you have.

I'm having the same problem with my brand new DV7T 7200 Quad. In BOTH Windows 7 and Windows 8. This seems to be somethign added by the Intel WiDi software. I've tried everything (installing all drivers, new USB3 drivers, etc) and nothing works. I ended up "uninstalling" the device and it hasn't shown up again. I would like to get it resolved though because my HP Recovery DVDs do not work. They fail at the end of the recovery with an error regarding USB yellow triangle. I suspect this is the reason. So my recovery discs are useless.

I want you to know I resolved this problem on my DV7T 7200. I downloaded the latest WiDi drivers from Intel:
These seem to be newer than the ones HP provides. I installed ALL other drivers first (display, chipset, etc) and then I installed the WiDi software (link above). The USB-IF xHCI USB Host Controller was recognized just fine. No more unkown devices.
Hope this helps.

I have the same issue. It started when I inserted a USB 3.0 flash drive. It did not show up when I used my 2.0 flash drive, it only started when I inserted the 3.0 device and has not gone away since. I have a Spectre XT Touchsmart 15t-4000.
