Occasionally support staff have seen PC's (especially Windows98) where the 8000 Series USB Hub is not properly recognized. The steps that follow have, to date, provided a successful WorkAround!
Check in the Device Manager.
If the 8000 series instrument hub is being misidentified as a 'USB diagnostic' device then continue with step number 2.
Remove the drivers for the USB diagnostic device by moving the 'Nodriver.inf' and 'Nodriver.pnf' files from the C:\Windows\INF folder to the desktop (moving makes possible a restore operation if this procedure fails to resolve the situation).
Reboot the system.
The system should now recognize the hub, the 8000 series instrument and the camera every time.
