should be attached.

I have two desktops that are also having this EXACT same issue. Im guessing it is a problem with the USB controller and the driver conflicting.

If there is a second USB controller or bus on the motherboard, then there will not be any issues running multiple plugable adapters. By adding a virtual bus (aka, a external USB hub), the display will be detected just fine, as we have determined on one of our test machines.

It looks like the software can see the device on the USB bus, but cannot communicate with the adapter. This can happen if the adapter cannot get enough power from the USB bus. Is the adapter connected to a powered USB hub? Does it work correctly i you connect it directly to the laptop?

Thanks

Wim

no, it does not work correctly still if attached directly to the laptop. we run powered 230w docks also for our laptops.

the usb hub we used on our test machine was not a externally powered hub, it is powered right over the USB.

again, we have this issue on both desktops and laptops. we have been moving the desktop computers over to quadro video cards to support the monitors though, but this issue persists with laptops (since we cannot add a internal video card).

Any other solutions/ideas? when we plug in the adapter, windows will loop the notification ding for auto detect as if it were being unpluged and pluged back in constantly.

There is not much more I can do to help here, as it looks like the adapter is dropping off the USB bus, so not directly a software problem. It could be faulty hardware, especially if it is happening on more than 1 PC.
