Please try these steps:

- see USB ports section and right click on it
- select uninstall and restart the computer
Windows should be able to reload the USB drivers and correct the issues possible caused by data corruption. If still the same, the USB ports might be having troubles not being detected in the system and there might need servicing from the manufacter or possible motherboard replacement since it was integrated with the mainboard.
Try reinstalling the usb drivers for your computer. You can also check to see if its a hardware issue by pluging a usb powered device like a cooling pad in the usb port. If it gets power, chances are its a software issue. If no, then its a hardware issue.
Click on start. Then click on Run.
Type in MS config.
Uncheck load startup Items.
click on ok and then click on restart.
Any application which turns on and starts using your port when the computer turns on would stop loading on their own and you will have free ports to use.
Well instead of repairing it have you tried an external usb pcmcia card? They are cheep and mine is usb2 4 port on a pcmcia and works fine. Just a sugestion for you. It runs about $14.00. I ave a 900 Compaq and the first to go was the dvd/cd [ replaced ] then the battery [ running off a cordless drill battery now ] and then the usb. I know your question was about fixing this but an easier way is described above. Over current on the usb port is no problem with the pcmcia 4 port usb card as if you need more current, it comes with an external power supply only if needed. I have never had to use this external supply yet. It supplies [ the card ] up to 800ma.
Hope this helped a little...
I have the same problem with my Compaq Presario V2000. Lost both USB ports and HP tells me that the motherboard has to be replaced at $300 +..I searched and found a PCMCIA card with two USB ports for $10. No problems with the USB ports on this card..great and cheap solution.
My belief is that the compaq usb ports do not have power limiting circuitry therefore allowing you to overload the output power on the ports. My ports failed after I downloaded into a burglar alarm system I was programming.
