We have an old serial port device that will not communicate with it's software properly on an Optiplex 790/7010 running Windows 7 (Enterprise x64). On a Optiplex 755 running Windows 7 (enterprise x64) it works fine.

Dell Inspiron 1545 Webcam was working upto last week but since a week it is not working, When I click the icon it is showing "please plug is supported Webcam". Webcam is already installed. Also it is not showing in Device Manager.
