I installed NI-488.2 V2. I tried all the ways suggested in the troubleshooting documentation, but it is still abnormal. View in the "Device Manager", it occurs under the "Universal Serial Bus controllers" as "unknown device" with status abnormal, neither in the "National Instrument GPIB card", nor in the "other device".
In addition, it alsways causes the win98 hanging.
Thank you for your attention.
