SYMPTOMS
If two or more identical devices (for example, network or SCSI adapters) are installed and you use Device Manager to update one device, the new driver is installed and the driver information (provider, date, and version) is updated. The new driver is used by all the identical devices. However, the driver information for other identical devices is not updated. The following registry entry is updated for the selected driver only:

HKLM\System\CurrentControlSet\Control\Class\{ClassGUIDforDevice}\000

If you check the driver details for one of the identical devices, you see the original driver information even though the device is using the new common driver.



CAUSE
The code only allows for updating the registry for the selected device. No attempt is made to find identical devices of the same class and update their respective registry entries.

If you manually update the other identical devices, their registry entries are updated and the new driver information is displayed. Or, if you update the registry entries manually, the new driver information is displayed.



RESOLUTION

 * 1) Start Device Manager.
 * 2) Double-click the next identical device.
 * 3) On the Driver tab, click Update Driver. This starts the Update Device Driver Wizard that you can use to update the driver.
 * 4) Repeat steps 2 and 3 for each identical device in the same class.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.
