When a USB device is connected, WinME freezes with the window "upgrading hardware database" displayed. A reboot with the hardware connected results in the same symptom. It boots OK without any USB devices, but will not let me connect any without the lockup. I attempted to upgrade the USB driver, but the computer either locks up during load or I get a message that the file could not be read and may be corrupt. I then tried removing the USB controller to see if a fresh install would cure the problem. After that, ME locked up immediately on booting up with the same message "upgrading hardware database". I then reinstalled ME. The reinstall took five hours to complete, but now I am back to my starting point. Can anybody help?
