MORE INFORMATION

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys and Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT, you should also update your Emergency Repair Disk (ERD).

To identify your USB Host controller, start Registry Editor (Regedt32.exe), and then locate the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\PCI

Under this key are several keys with names similar to:

VEN_1002&DEV_4742&SUBSYS_00000000&REV_5C

Under each of these keys is a key with a name similar to:

3&225b1d41&0&0008

Click the key under the first VEN... key. In the right pane, note the data values for the following registry values:

DeviceDesc
HardwareID
Mfg

The DeviceDesc value is a REG_SZ value that contains a description of the device. The HardwareID value is a REG_MULTI_SZ value that contains the hardware revision of the chip set used in the device. The Mfg value is a REG_SZ value that contains the name of the hardware manufacturer.

Check the DeviceDesc value in the key under each VEN... key until you locate the key for the USB controller.
