USB Port replicator Display issue W8 V7.2

fentong · 04-25-2013, 02:41 PM

Hello, I have the HP USB2.0 display link port replicator and I'm using Windows 8 on an HP Ultrabook. I just downloaded the Displaylink V7.2 M0 software but the display connected to the USB port replicator does not display. I've previously tested the USB hub with an XP laptop connected to the Port replicator and the display worked fine so I doubt it's an issue with the hub.

Please offer any troubleshooting suggestions?

Thanks,

Hello, the only troubleshooting step I can think of is to remove any old/stale USB devices... You may do that with USBDeview: http://www.nirsoft.net/utils/usb_devices_view.html

Sometimes when I install a particular Windows Update or install a new DisplayLink driver, the previous USB drivers/detection logic will break because of stale/conflicting devices. When this happens, I would not be able to get any screen output, but perhaps network/audio from the hub. Try getting rid of (removing) the stale/old USB devices, especially all the ones relating to the DisplayLink hub. Next, reboot the PC. Finally, re-plug the hub. You should see USB detection happen for all the DisplayLink pieces again and hopefully your problem will be fixed.
