We have a Dell Latitude Rugged laptop here. Its running Windows XP. It was brought to me with reports that the COM/Serial port is no longer working, along with the USB ports. I've done a bunch of troubleshooting and sure enough, I can plug in a USB mouse and it lights up, but Windows doesnt see it (no USB sound, or installing icon, or anything changed in the Device Manager). The mouse remains lit, but the pointer doesnt respond.
I've plugged in a netcam, but again, nothing. I've also tried a USB thumb drive, it briefly lights up, but then goes dim, and nothing happens in Windows. I've tried disconnecting the power and batter, rebooting several times, removing USB devices from device manager, rebooting several more times, disabling USB in the bios and going into Windows and rebooting. Tried a reg key about not allowing Windows to sleep the USB ports..
I dont think its been a driver update, since the laptop is offline most of the time. I did try running Windows update myself, but didnt find a new USB driver.
I find it strange that the USB mouse lights up, but Windows doesnt see anything.
