Here is what you can do to refresh the USB ports: 1. Right click MY COMPUTER 2. Select PROPERTIES 3. Select HARDWARE 4. Select DEVICE MANAGER 5. Select UNIVERSAL SERIAL BUS CONTROLLERS 6. Right click on each USB CONTROLLER and select Uninstall 7. Uninstall all entries 8. Reboot your computer 9. As your computer re-boots it will reinstall all USB connections it detects THEN, when all other USB items have been configured and connected by the system, you then should try connecting your USB drive
Check the actual ports, visual inspection. Look for consistancy of the pins, and guide. If one is bent or missing, that can short out the ports, or blow out the integrated circuit.
If you are using a usb keyboard, try to start up and go into the setup using the keyboard. If you can, the driver for the ports might be damaged, causing the problem in windows, but not in the bios startup.
You can purchase a usb board that can give you new ports, and deleting the usb hub from the hardware manager (check help) and re-detecting the device might repair a damaged driver.
You can plug a USB hub into the working USB port on the computer. The USB hub can have several ports so you can plug in several USB devices.
I suggest you get a powered USB hub because if all the devices that you plug into this hub exceeds 500mA then your computer's USB port will stop working because it could not supply enough current.
You will not need to plug in the power adapter into the hub if the device/s do not overload the computer's USB port.
Windows XP has Drivers within the operating system to Install and setup USB Ports.
Here Are your options to Provide A Fix.
1: )The USB Port May Be Disconnected From The motherboard.
2:) The Device you are trying to Connect ( Pen-Drive ) May be faulty And Not Recognised By The Computer.
3:) The USB Cable Or Socket May Be Faulty.
Solution:- Try Connecting the Device To An Alternative ( different ) USB Socket On The PC.
Solution:- Try Connecting a Different Device to the USB Port. i.e MP3 player Or Digital Camera et,c.
Solution:- Check that the USB Header Cables ( from Motherboard To USB Ports ) Are connected Or incorrectly Connected.

Hopefully Windows will re-detect your USB devices and get them back operational.
1.1 is the older usb connection. 2.0 is faster and is found all all new laptops and some older laptops and desktops. 2.0 just basically is a faster usb port, and can read more devices compared to the 1.1. you can still use the 1.1 usb port like a 2.0 port but like I said it wont always read or just will read slower. 2.0 is better. You could also find 2.0 usb HUBs that you can plug in to the 2.0 port and have extra ports depending on the HUB, if you choose not to use the 1.1 or 1.0.
