I have a Toshiba Satellite M55-S139 laptop. It has a clean install of Windows XP on it, along with all the updates from Microsoft Update (including SP3) and is running Microsoft Security Essntials.
When I first updated everything there were some pcs of hardware that were still unidentifiable so I went to Toshiba's website and downloaded some of the drivers to install. All went well, and the computer seemed to be functioning perfectly. However, I went to plug in a USB device and the computer froze. Unplugged the device, and it remained frozen...rebooted (only way to unfreeze it) and everything seemed to work fine. I tried a DIFFERENT USB device and the computer froze again proving it wasn't a one-time occurence or anything to do with the 1st USB device. So I rebooted and tried a third USB device, however this time I inserted it in a different USB port...same result, it froze. I went to the device manager and uninstalled everything related to the USB Bus, and did a soft reboot of Windows. Windows Successfully discovered and reinstalled the drivers for the USB bus. I tried to access a USB device again, 4th device 3rd port...same result.
I went back to Toshiba's website to make sure I had the right BIOS installed and see if there was anything there for the USB bus...right BIOS installed, and nothing for the USB...so now I'm stuck!
