USB Display Adapter not recognised

[DuncanGardner]

My WavLink USB 3.0 HDMI display adapter is not recognised when I plug it in. Originally I was using it on a W7 laptop in a USB 2.0 slot, and I had to wait ten mins before it would be recognised. I even bought a USB 3.0 adapter, no difference. Eventually that stopped working. So now I'm trying it on a Vista laptop.
I have latest DisplayLink s/w installed, and service is running.
However in Device Manager I don't have any USB Display Adapter listed, not even the heading.
I don't get a "bing" as you usually do when a device is plugged in. I am using a USB port on the laptop, not externally.
The adapter does have a power light, which goes on. Also the monitor flickers between analog/hdmi, so some sort of signal is getting through.
I've even tried a second DisplayLink adapter, identical model.
Sounds like a hardware failure?

In response to the debug steps (same for Vista machine and W7):
Check DisplayLink software is installed
YES
Check the DisplayLink Service is running
YES
Check the DisplayLink USB device appears in the device manager.
NO

Support Tool file attached for Vista "Cabernet"

Should I return the adapters? It's odd that they were working, then stopped. I've also tested in a Windows XP machine.
The unit is labelled as a WavLink, but was purchased as Winstars WS-UG70H5

Hi

From looking at this page:
http://www.win-star.com/eshop/article.php?id=41

The WS-UG70H5 is not a DisplayLink powered product.

Thanks,
James

Yes, that is what it looks like. But I think my device is just mis-labelled by i-Tech. There's nothing on the device itself that indicates it is WinStars. I tried the drivers anyway - no luck.

Hi,

In device manager do you have any unknown devices listed?

if so can you can you provide details of what they are?

Thanks,
James

Hi James

I have the same problem as DuncanGardner.
My laptop is running Windows8, and I checked the first two steps (installation and service running). I installed the proper driver (for Win8).
But in the Device Manager I find no "USB Display Adapter".
Instead of this, I have multiple additional normal USB's:
"Generic SuperSpeed USB Hub"
"Generic USB Hub"
"USB Composite Device" x2

So I suppose it has been recognized, but not for what it is?
Can you help me on this?
Thanks a lot in advance

This is the docking station I have. I use it with an Asus Zenbook UX51VZ and want to use a DELL U2412M Monitor.

Hi,

Which port on the dock are you trying to attach the Dell monitor to?

Can you try attaching to the other ports on the dock?

Thanks,
James

Hi James

I tried attaching it to the VGA of the docking station, as usual with monitors.
Note that it already functioned in the past.

Thanks for the help

Hi,

Thanks for the information.

Can you try power cycling the dock?

To do this follow these steps:
* Disconnect the dock from the notebook
* Disconnect the dock from the mains power
* Reconnect the dock to the notebook
* Reconnect the dock to the mains power

If you can please try connecting your monitor to the DVI / HDMI port on the dock.

Thanks,
James

Hi James

Took me a while to find again a DVI-HDMI cable. I power cycled the thing and connected the monitor with DVI-HDMI. Still nothing happening. Maybe you have another idea?
