Do any other devices work on any of your USB ports on the desktops? Does the memory stick work with a port that works for another device?
If all of the ports fail, check the Device Manager (for Windows OS) - you may have a driver issue. This is reached through the Control Panel (under Hardware or System). The exact titles will depend on the version of the OS.
When you scroll through the list to the USB controllers, look for a triangle with a red x or a yellow triangle. The right click (or double-left click) and try to update your driver or roll back the driver to an older version that worked.
If only a few ports fail, then are you dealing with the front ports or the rear ports? If the front ports (case), then you might want to check if the header cable is fully connected to both the case and the motherboard. This requires opening the case with the appropriate care.
Unfortunately, some new USB devices pull too much power through the port and can burn them out. (Those that charge on the computer are the most likely culprit.) If you have a few working ports, get a USB hub that is self-powered. (Get a good one or only use the AC adapter when there are more than 4 devices connected to the hub.)
Unlikely to be issues with the OS. Have you recently upgraded to Win 7 from Vista or XP? and did the USB ports work with this OS? Do ALL usb ports fail or is it just one or two and are these the front USB's or rear USBs?
Some computers have both USB ports on the front and back of the case. The ones on the bark are directly off the motherboard while the ones on the front are usually connected by a separate cable. If you are trying the front ports, try one of the rear ones instead. if it works in the back, that cable may need to be reconnected inside the case.
these front usb ports cause prob lem always kindly change the whole panel with usb ports in front they are faulty and giving problems and will create more problems if u dont change them kindly get new one u can find them easily on any store and simply chang them see the connector going to the motherboard plug it out and plu the new one at same location
The message comes up when a USB 2 device is connected to a slower USB 1 or 1.1 port. It is only to advise you that the devise will operate faster on a USB 2 port. If your computer has only USB 1 or 1.1 ports, you will always see the message. You can buy and install a card with USB 2 ports and install it. It will come with the USB 2 drivers. Install the card and the drivers and then connect your USB 2 device to the new hardware and you should not see the message anymore.
Good luck, And let me know ho it works out for you.
As you stated the device works in one slot but not the other , tells you there is problem with that usb port , don't use those ports , best thing to do is purchase a PCI USB card if you need more USB ports .
