+==== USB 3 Port ====
+If you have a Bluetooth dongle connected to a USB 3 port on your host, you may experience decreased Bluetooth performance.  Popular motherboard manufacturers, like Asus, have white papers on this subject.

+The easiest solution to mitigate the RF interference is to get a USB extender cable and plug the dongle further away from the host's USB 3 port.
