Cannot Disable a USB Host Controller or Other USB Device After Attaching a USB Keyboard (283560)


The information in this article applies to:

  • Microsoft Windows XP Home Edition
  • Microsoft Windows XP Professional
  • Microsoft Windows XP 64-Bit Edition
This article was previously published under Q283560

SYMPTOMS

After you attach a USB keyboard to your Windows XP-based computer, you cannot disable a universal serial bus (USB) host controller, a USB root hub, or other device in Device Manager.

CAUSE

This behavior occurs because of the keyboard's being a system-critical device. Attaching the USB keyboard removes the disable option from the Properties menu for the USB device.

STATUS

This behavior is by design.
