First off make sure the USB drivers are loaded. You should be able to go to your windows update and microsoft will load a generic driver. If the drivers are loaded but they still dont work you can look in the bios make sure usb is enabled. If you can not find that in the bios set it to factory default. If after this they are non functional then u have fried the host card on the board and they will never work again. Some electronics can cause a dead short to the usb host controller this is what Ive found in my shop most often. Now if this be the case you are not out of luck. You can buy an after market express card slot USB card. This will allow USB function via 2 USB ports in the expantion card slot.
I just fixed this problem on my dv1000. The problem I found was apparently the USB ports on lower right and left side only mounted on the mobo with light soldering and no soldering on the other side of mobo. Due to heat I guessed, they came loose. I opened the mobo (using guide from a pdf file on the net, sorry i forgot the exact guide but you can ask uncle google). I took the mobo out and resolder those two ports with plenty of solder from the top surface only of the mobo as I unable to access the other side. Now they work again like charm. The top right USB is different beast. It is on different card along with S-Video port and apparently in permanent damage.
