Troubleshooting & remove usb from reg.

Verify that USB is enabled in the BIOS Setup Utility.
Not all BIOS Setup Utilities have the option to turn it on or off.

Note: This option is only on older motherboards and is not the same as Legacy USB Support on current motherboards. Enabling Legacy USB Support allows you to use your keyboard while starting, but has no affect in Windows.

4.Verify that USB is installed correctly in Device Manager.

5.Verify that the cable is plugged into the USB port correctly on the motherboard.

6.Verify that the cable is plugged into the USB device correctly.

7.Uninstall the program software that may be installed for the USB device.

8.Restart the computer.

9.On your screen, locate and click the Start button. From the Start menu, click Run.

10.In the Run dialog box, in the Open text box, type: Regedit. Press the ENTER key.

11.Double-click HKEY_LOCAL_MACHINE.

12.Double-click ENUM.

13.Double-click USB.

14.Under USB there may be keys that begin with VID_.

15.Select each VID_ key, and then press the DELETE key.

Note: If the client has a Profile or Astro, do not delete all of the VID_ entries.
Open and view each one individually.
Delete only the ones that pertain to the USB device that you are trying to install.

16.When prompted "Are you sure you want to delete this key?", click Yes.

17.Disconnect the USB device.

18.On your screen, locate and click the Start button.
From the Start menu, click Shut Down.
In the Shut Down Windows dialog box, click Restart, and then click OK.

19.After the computer has restarted, follow the directions for the USB device on how to install it or use the tools.

20.The USB device should automatically be detected correctly.

Note: Verify that the client is not using a USB hub.
Plug the USB device directly into the USB port on the motherboard or the case for troubleshooting steps.

Before changing or modifying the Registry, you may want to make a backup copy.

USBVIEW on the Windows 98 CD under D:\Tools\Reskit\Diagnose (where D:\ is the drive letter of your CD/DVD drive) is a good troubleshooting tool to verify the USB device is recognized correctly.
