I have had issues when loading Plantronics headsets on laptops and the computer not seeing the device. If I move to another USB port it finds it? Is this due to USB 2 ports and USB 3 ports being the difference and how would you tell which port is USB 3 or USB 2? The desktops all find the headset right off, it is just the laptops that give me issues. I just keep moving the USB connector to another USB port until it finds it.
