It depends on what McaFee software you have installed. Perhaps your administrator blocked certain classes of usb device using McAfee HDLP?
McAfee version is 11.6.477, but I did not see a setting for HDLP. I did however fix the issue by moving the USB Dongle from the front of the PC to the back where I could plug it into the mother board. This fixed it.
Thanks for your response.
