    Ok, so I tried to reinstall the usb drivers but that didn't help. It still can't recognise any devices. If I plug my mouse in, the optical sensor starts to shine, but it doesn't respond. The mouse is working perfectly on any other PCs, I've had it for five years and I've never needed to install any drivers. I tried other usb devices and they don't work either.

   I have a P4P800-MX motherboard given to me by a friend who upgraded his desktop, it also has the USB problem. Unfortunately this is a known issue, I read numerous posts on a few forums, may have been the ASUS site itself detailing the problem. A few P4P800-MX owners had returned more than one board while it was still under warranty. The best solution was to buy a USB 2.0 PCI card and and not use the on board ports.  A few owners mentioned that devices connected to the faulty ports became damaged so I'd really recommend not using the on-board USB ports.

    I would try the uninstall one more time

    follow these steps

    Go to start

    control panel

    select device

    remove device



    on restart windows will auto find device and install drivers automatically

    there are normally three messages with auto find,

    device found

    software installed

    ready for use

    when all pop ups disappear then its ready for use.

    Reboot to save your settings ,

    don't forget SP2 updates

    If problem persists then time for a new one

    or try www.assus,com

Usb port can't work

There are basically 2 reasons why USB ports will not work besides being faulty.
1. The drivers are not installed (inf files)
2. The ports on certain motherboards can be disabled in the CMOS or BIOS setup.

To check if the USB drivers are installed you can open control panel>device manager. Scroll down to "Universal serial bus controllers and make certain these are present and installed correctly.

Also make sure your USB device is functioning properly by plugging in to a USB port on a different computer.

Please let me know if you need any further assistance.
Best wishes,

Asus P4p800 se Mainboard USb Ports not working

it would seem that you are not the only one with this problem with the USB's, the only soloution i have found that people say works is to reset the cmos (remove motherboard battery without any power cord attached) for 10 mins, or, go into the bios and reset to default/optomised defaults

hope this helps

kind regards

Usb cannot recognized

Reinstall your USB drivers:
Navigate to Device manager, find a branch named "USB Controllers" or similar
Right click the one thats the problem (or all of them if you dont know which), select Uninstall
Reboot your machine and windows will autodetect the USBs and reinstall their drivers

Check the BIOS and see if they are enabled...

Disable power management on the USB hub To preserve power, Microsoft1.gif Window XP tries to disable USB when a device is not used. Under certain circumstances this function does not work and may cause USB devices to fail to respond when called. To resolve this issue, disable power management on the USB hub by doing the following:
  1. Click Start , and right-click My Computer .
  2. Click Properties , then click Hardware .
  3. Click Device Manager .
  4. Double-click the Universal Serial Bus Controllers branch to expand it.
  5. Right-click USB Root Hub , and then click Properties .
  6. Click Power Management .
  7. Deselect Allow the computer to turn off this device to save power .
  8. Repeat Steps 5 through 7 for each USB Root Hub.
  9. Click OK , and close Device Manager .
