Hi guys,

I have just registered in hope that someone will solve my problem with p55a motherboard. All of my usb ports work normally, but two of them should work as a 3.0 usb. In the device manager I don't see NEC USB or sth like that ( http://imageshack.us/photo/my-images/64/managerp.jpg/ ). I've installed all of the drivers, and when I click Usb 3.0 host controller utility the message "Host controller not found" appears. Thanks in advance for ur help.

Welcome to Tom's Forum! :) 

Did you Disable the USB in the BIOS?

BIOS:
/Integrated Peripherals
USB Controllers -> Enabled
USB Legacy Function -> Enabled
USB Storage Function -> Enabled
Onboard USB 3.0 Controller -> Enabled

It was the first thing I checked (: All of the usb functions are enabled :/

I. The next thing I would try is to Clear CMOS use the Jumper Method; see http://www.youtube.com/watch?v=rdHH9KrceR0

II. Failure look for shorting or grounding interfering:
You can try Lazyman's Breadboard -
* Disconnect ALL Front Panel & USB Headers ; keep only the PWR & Ground (Power Button)
* Disconnect ALL peripherals excluding the Keyboard/Mouse
* Unscrew both the MOBO and PCIe screws

Pull the MOBO away from anything conductive and supported by a towel ; Power On

III. Failure update the BIOS to F7 "Improve USB3.0 compatibility"
Q-Flash - method to flash BIOS

Flash Drive MUST be: USB 2.0 (not USB 3.0), FAT-32 Formatted with ONLY (1) partition, and shows-up as a HDD.
Use the Q-Flash procedure - video:

Part 3 - http://www.youtube.com/watch?v=EX78S4qyHu0

IV. As noted below, eSATA issue, otherwise it would seem if everything else is working and none of the above solved this issue that the MOBO or at least the NEC chipset is damaged.

In the specs I did note the following:
Up to 14 USB 2.0/1.1 ports (10 on the back panel (Note 4), 4 via the USB brackets connected to the internal USB headers)
(Note 4) Two share the same ports with USB 3.0 and another two with eSATA.

IMO - Load Optimized Defaults in the BIOS and next you can 'try' to uninstall ALL of the USB devices listed and reboot. Keep in mind to use a PS/2 Keyboard or all of the sudden you'll lose control once uninstalled.

OK It's an old thread but I wanted you to know that after spending 4 days trying to get the USB3 controller to even show up in Device Manager, I came across your post. Going down the things you listed, one by one, I finally resolved the issue by pulling the motherboard and doing your "lazyman's breadboard". Sure enough there was a screw under the board and the issue is now resolved. Thanks!
