Windows 8 issues - USB display adapter

miket71 · 11-04-2012, 12:45 AM

Hello,

Hello, I recently upgraded to Windows 8 Pro, and I have the WUSB to HDMI DisplayLink Adapter from Cables Unlimited a.k.a. Warpia, IOGear GUWAVKIT2, and a few other names that it sells under. The last WUSB driver I tried to use is version 14.2.174.8, with no luck. When we plugin the USB adapter, it tries to plug-n-play, but doesn't complete like it did with Windows 7, as there were about 7 Device Connect sounds, and the screen would flash a couple times as it initialized. With Windows 8, there are only 2 Device Connect sounds, with no screen flash. If the device is left connected, the computer blue screens after a few minutes. Hopefully one of the vendors are working on a new driver for Windows 8. We are using the latest DisplayLink software. Thanks for reading, and for any help. Mike

Hello, I just made another attempt at loading the WUSB drivers and DisplayLink software. I uninstalled both the driver and software, and rebooted. Then I put the DisplayLink USB dongle into the USB port on the computer. Everything installed except for the USB Root Hub for it with a yellow exclamation symbol and an Error 31. When I tried Updating The Driver manually, it would go online to look for one, but would come back to say that it had the best driver on the computer already, despite the yellow triangle symbol. Then I tried reloading the Windows 8 compatible DisplayLink software again. It would start to load, then it seemed like it would quit in the middle of the install. I'm used to clicking Finish at the end of any install which would tell me that it was successful, but that doesn't happen. However, it shows two entries in the Programs and Features list (DisplayLink Core Software and DisplayLink Graphics). The DisplayLink tray icon does not appear at all. Then when I load the WUSB driver for it, that loads fine, but still it does not work. Each time I try to load the driver, it wants to update the firmware on the USB dongles, but I have been skipping that part because I know that they are updated. When the dongle is connected at the PC, the green light flashes quickly for a few seconds, then goes steady, then flashes rapidly again for a few seconds, then shows steady, and does this over and over with no result. I have seem the PC blue screen if I leave the dongle in there too long. Thanks for any help and suggestions. Mike

I think your issue is with the UWB link. These drivers are not DisplayLink drivers, so I can't help get these working. But looking at the system details, it shows that a DisplayLink device has never been detected on the USB bus:

Have ImationLink USB adapter, worked just fine with Win 7, after upgrade to Win 8 no video signal, audio connection seems to work. Uninstalled and reinstalled DisplayLink software and driver several times with no effect. Solution?

Hi, I am running windows 8 on a new Lenovo w530. I have installed, uninstalled, reinstalled drivers etc countless times (including all the ways suggested in this thread) and have had no luck). When wanting to extend my display I get the flashing screen. If I instead duplicate my display my second screen goes black, but has a windows arrow in the centre and my primary screen switches to low resolution, but the flashing ceases. If I switch my secondary screen to off (ie only keep my primary display) then my resolution of my primary screen goes back to normal and the secondary screen goes blank.

Log from the displaylink support tool is attached below (I ran the tool while the primary screen was flashing)

Any help suggestions would be much appreciated.

OK - it looks like we are reproducing the issue people are having with uninstall/reinstall. It appears that if you try and uninstall DisplayLink Core Software, it looks like its uninstalled, but if you press F5 to refresh the Programs list, it is still there.

If you try and uninstall again, then it should disappear this time. If not, try uninstalling the "DisplayLink graphics" package and see if that works... Basically, don't reboot and try and install again until "DisplayLink Core software" and "DisplayLink graphics" have both disappeared from Programs - even when you press F5 to refresh.

I think this is why some of you are still having issues.

Sorry about this... I can understand it's a big pain. I'm now off to sacrificially burn some engineers responsible for this screw up and make sure it's fixed in the next release in a few weeks time.

When I previously uninstalled the software, I checked to ensure it really was gone by refreshing (and rebooting). But to leave no stone unturned, I retried today and did everything as described (which is what I did previously anyway). I got the same result with the flashing screen.

I did the uninstall again, this time ran regedit and deleted all entries relating to displaylink, there were some that I couldn't delete though. This time the problem was very much the same, except this time if I try to switch to "duplicate displays" the flashing stops for a second or two, my laptop display goes to low res and then it switches back to "extend displays" and my laptop display reverts back to flashing high res....

I will keep trying to play with it and post if I manage to become successful

OK - the flashing screen is is a different issue, but also known. This is caused by a conflict between DisplayLink and the latest NVIDIA Windows 8 drivers, released by NVIDIA at the same time as we released our Win 8 driver.

The work around for now is to downgrade the NVIDIA graphics driver to an older version before installing DisplayLink software. This should solve the issue.

I tried rolling back the NVidia driver, and it helped to stop the flashing screen issue, but now I just have a blank second screen. (note that this only applies to my usb screen, my vga output has always worked fine)

I also have an unusable dock. I've wasted days on this thing.

I have the flashing screen problem, and installing an old NVIDIA driver did nothing different.

When will an update be available, obviously you guys know this is a problem??
