Windows 7 Update kills USB DisplayLink

No change in my status of the two USB monitors. Only one works as before so I don't think the new DisplayLink drivers were able to address our situation. I even tried using a completely different USB port than before (on a separate host adapter) and while everything appears to have installed properly (audio, webcam, USB monitor... all in the Device Manager without any errors appearing), only one monitor works at a time.

Same as before when both connected, one is active. When I unplug the active one, the other one becomes active.

I really don't want to reinstall everything and revert back to WinXP to get both displaylink monitors working!

I think your situation is different to everyone else's on this thread. Am I right that you have two 2263DX, each with a 7" DisplayLink USB display?

If so, then I think when Samsung manufactured these 7" displays, they didn't program a unique USB serial number in the device and it is set to all zeros. This means that Windows cannot distinguish between the two 7" monitors on the USB bus, so our software cannot communicate with both of them at the same time.

So unfortunately this is due to a manufacturing issue with the Samsung display, rather than a bug with the DisplayLink software. I suspect you also only see 1 screen under "USB Display Adapters" in device manager when both are plugged in?
