Removable Storage Device Does Not Work After It Is Removed and Reinserted


When you try to use a previously installed removable storage device (for example, a removable CD-ROM drive for a portable computer), the device does not work. When you view the properties for the problem device in Device Manager, you receive the following message:
This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)


This problem may occur when you:
  1. Install a new removable storage device (for example, a memory card, a PC Card storage device, or a USB storage device).
  2. Remove the previously-installed removable storage device from the computer.
  3. Reinsert the previously-installed removable storage device.
When this sequence of events occurs, Windows 2000 may not clean up a reference to the removed device. This prevents the device from being enumerated and configured correctly when it is reinserted.
