Device is being used by another program

The microscope was instantly recognized and correct driver installed. The software installation went fine. The software can detect when the scope is plugged in and when it itsn't. When it is plugged in, I get a message saying "Connecting to digital microscope" but nothing ever happens.

I know the USB ports are fine because they are used for many other devices cameras, ipods, gps, phones that function as expected. I have uninstalled software and driver. Have reinstalled from the CD and from the manufacturer's website. Tried two different webcam softwares - ManyCam also recognizes the microscope but says that "it may already be in use by another application, please stop the other application".

This happens even after a reboot where nothing else is open or running. The manufacturer just shipped me another microscope with same results but provides no support.

This is supposed to be plug and play with XP, Vista, and Windows 7. How do I find out what is wrong or what else is tying up the microscope? Where do you look to find out what applications are using what devices or vice versa? I have tried starting the software before plugging in the scope and after. Any help would be greatly appreciated.
