I believe the Barcode scanners are going to show up as USB-HID (same as a keyboard). This scenario is similar to connecting two keyboards and trying to limit the computer responding to keystrokes from each of the keyboards.

 

If the barcode scanner shows up as a com port then you may be able to specify which com port you want to read the characters from.
