You need to un-install ALL of your USB items in Devices (as per your image) - right-click on each one in turn and click on un-install. When all have been un-installed re-start your computer. Your USB devices will then automatically be re-installed.
Often this is a static problem. Turn off the power rocker switch on the back of the pc. hold down the "power on" button on the front of the pc for 1 minute then release. Turn the power back on via the rocker switch on the back of the pc. hopefully you'll have your devices back.
Refresh USB Ports Use Drive clean up to remove USB device drive info from the registry click here or In device manager Uninstall EVERYTHING under the heading USB, reboot the PC let XP find and install new hardware. Your equipment should now be recognised.
All was working great untill the other night when i connected my psp to the USB port then nothing. USB ports and card reader just stopped. I can still charge the psp and when i put a card into the card reader it lights up green but nothing.
