Dell 9200 Laptop USB Ports not working

Recently none of our USB ports are working properly on the DELL 9200 Laptop.  I put a usb mouse or my usb key in the usb port and no response.  

I have reinstalled Windows XP pro and no good.  I though maybe windows crapped out but looks like that was not the case and the USB ports are still not responding.  Please can anyone help.

Thanks....

Have you checked in the device manager to see if there are any indicators showing problems.
to do this click-->START-->RUN type in "devmgmt.msc" and click -->OK
In here click the [+] sign to open the--> Universal Serial Bus Controllers   check if there are any yellow or red marks next to the Universal Serial Bus ports.
post back here with your info.

I was a dell field tech for a while. If a reinstall did not correct the issue and you do not have a warranty, your best bet is to get a 9200 with a broke screen from ebay and do a motherboard swap. These motherboards had a problem with a component that caused the usb system to just quit responding. I can give step by step instructions on the replacing, all you need is a small phillips screwdriver. Sorry for the bad news.

First check inside the BIOS, there may be a "Legacy USB" setting or something similar. If that doesn't help, get Knoppix, boot with that CD and try the USB things with that. If it won't work there, you have a hardware problem and your best option would be to buy a PCCard USB (and if possible combined with firewire) adapter.

You burn the iso to a CD using nero or a similar CD burning software that can burn iso images, then boot your PC with that CD and check if a USB mouse works. Knoppix is a linux distro that runs completly off a cd and doesn't write anything to HD. It starts a GUI similar to Windows and has very good plug'n'play support.

Note: To boot from the Knoppix CD you need to set the computer's boot order (in the BIOS) to boot from the CD before the hard drive. (If it's not already set that way.)
.
Knoppix is an operating system that doesn't even need a hard drive to run.
(Don't worry. It's easier to use than it sounds like it is....)
.
You are basically determining if the problem is Windows or the hardware by using a non-Windows operating system to operate the hardware.
