Hi Dan,
If you are able to locate the USB ports and controllers in the Windows Device Manager, right-click each USB entry shown there and uninstall it.
Once you have removed all the USB entries, restart your computer and allow Windows to automatically reinstall the USB drivers for your USB ports and controllers.
You can now check to see if your USB ports are working with all your USB devices.
I also recommend reading through this article:

Let us know how this works out for you.
Good luck,
James

Hi Dan,
Just to clarify, you have two problems, namely: (1) Your Windows XP laptop's USB ports are not recognizing devices that you plug into it; and (2) Your laptop's built-in WiFi adapter is not working, so you can now only connect to your local network or to the Internet via a LAN cable. Is this correct?
If so, then the most likely solution is for you to properly re-install or update your laptop's motherboard drivers and other firmware components to the latest versions for Windows XP...
To do this, you can install and use Driver Reviver, which can be downloaded from http://www.reviversoft.com/driver...
Or, you can insert your driver disk into your CD / DVD drive, launch the provided installation wizard and follow the succeeding prompts provided by the wizard to re-install your laptop's motherboard drivers and firmware components...
Or, you can follow the steps below...
STEP 1. Insert your driver disk containing your laptop's motherboard drivers and firmware components into your CD / DVD drive -- This driver disk is normally bundled with your laptop. If you don't have the driver disk, go to your laptop manufacturer's website and download the installers for your specific laptop make and model's motherboard drivers and firmware components;
STEP 2. To check if your motherboard drivers and firmware components are properly installed -- Go to Control Panel and click System. Then, click the Hardware tab. Next, click the Device Manager button;
STEP 3. To properly install or update the driver for your built-in Wi-Fi adapter -- Select and expand Network adapters from the dropdown. Then, right-click on your built-in Wi-Fi adapter and select Update Driver to launch Hardware Update Wizard. Follow the succeeding prompts provided by the Hardware Update Wizard, keeping in mind to point to the location of your driver disk or the directory where you saved the installers that you downloaded from your laptop manufacturer's website; and
STEP 4. To properly install or update the driver for your USB ports -- Go back to Device Manager. Then, select and expand Universal Serial BUS controllers from the dropdown. Then, right-click on Generic USB Hub and select Update Driver to launch Hardware Update Wizard. Follow the succeeding prompts provided by Hardware Update Wizard, keeping in mind to point to the location of your driver disk or the directory where you saved the installers that you downloaded from your laptop manufacturer's website.
Hope this helps...
