Example:
Both monitors plugged in and powered on...
A is ACTIVE | B is INACTIVE
Unplug A: B is now ACTIVE
Re-Plug A: A Stays INACTIVE, B is still ACTIVE
Unplug B: A is now ACTIVE
I can not get both monitors to remain ACTIVE and run simultaneous under Windows 7. I think I was able to use both at the same time while running Windows XP.
I'm using the latest versions of drivers for the respective hardware.
Help?

I think this is a different problem and can happen when you have 2 devices that the manufacturer has programmed with the same serial number. It means that Windows cannot distinguish the 2 devices on the USB bus, so only one of them works at a time.
You should be able to check the serial number of the USB device in Device manager.
What is the product you have?
