Please help. I have an HP Pavilion dv8000 notebook running Windows XP with service pack 3. All of a sudden i plugged in my USB wireless mouse and received the message "USB Device Not Recognized". So I went out to the internet and researched this error and I have tried anything from uninstalling the USB's thru device manager, pulling the battery and unplugging the laptop to restart the motherboard and countless other tricks. I tried to reinstall the drivers from the CD that came with the computer and that didn't work either. Please help, this is a great laptop and everything works except the USB ports. I was told that the last resort was to replace the motherboard. Any ideas that I can try before scrapping the whole computer and getting a replacement?
