Multiple ARM devices running USB-serial communication on a single PC

Hello,

I am trying to connect multiple ARM devices running the "USB virtual COM port Demo" application on a single PC using many USB ports. I am only able to connect up to 2 devices.
When trying to connect more devices the virtual COM ports on PC stop working properly. Does anyone know what may be going on?
