USB Keyboard and Mouse May Not Work After Restart or Hibernation (305177)

SYMPTOMS

When you restart your computer or when you resume a hibernated session on your computer, you may experience the following symptoms:

Your Universal Serial Bus (USB) keyboard or mouse may not work until you shut down the computer and then restart it.
When you open Device Manager, your USB devices appear under the Unknown Devices branch.
The computer adds the following key to the Windows registry:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Enum\USB\VID_0000&PID_0000

CAUSE

This problem can occur if both of the following conditions are true:

Legacy USB support is enabled in the basic input/output system (BIOS) settings on your computer.
The computer uses an Intel 82801BA I/O Controller Hub (ICH2) chip to control your USB devices.

To determine if your computer uses an Intel 82801BA I/O Controller Hub (ICH2) chip, expand the Universal Serial Bus controllers branch in Device Manager, and then look for a device that is similar to the following:
Intel(r) 82801BA USB Universal Host Controller

When you restart your computer or when you resume a hibernated session on your computer, the computer redetects your USB devices, but it does not enumerate them correctly. When this occurs, the USB legacy support settings conflict with the settings that the Universal Host Controller Driver (UHCD) attempts to enforce.
