This tool will allow you to determine the state of your USB ports: USBDeview http://www.nirsoft.net/utils/usb_devices_view.html It will show past or present connections to ports.

If your laptop is newly bought, you should consider returning it to the store for repair.

If you have a printer connected to your laptop, unplug it from your PC and then turn off your PC. Unplug the power cord of your PC from the wall outlet for 2 or 3 minutes (this drains the power from everything). Plug it back in and boot up your PC. Then try using your other USB ports. Are they working now?

If you have a laptop, a similar solution to the one above is the following: A simple advise to all Laptop owners without needing to reinstall or updating or damaging your BIOS.

Instructions:

• Unplug all the cables that are connected to your laptop
• Remove the battery of your laptop
• leave it for 1 min. and dont be hasty
• Plug everything back and turn your laptop on. Please remember, Old HPs, VAIO and some Dells will not reset the device state UNTIL you take the battery out for 1 min or more. There is always power going through it. That’s why your laptop will fully drain a battery even on ‘shutdown’ after a few days while not being connected to the A/C outlet.

If all USB ports are not working try to upgrade the chipset drivers.

You should read your motherboard manual.

Try doing this too: Go to DEVICE MANAGER. Disable ALL UNIVERSAL BUS PORTS. Enable THEM AGAIN.

Microsoft has a few answers, and a ‘fix-it’ gadget - that you could try, ( I have added that to my little toolbox - I also saved a copy of my toolbox on CD, as well as on a usb flash drive). Go to this link: http://support.microsoft.com/kb/817900
