All Bluetooth devices use the same 2.4GHz radio frequency to communicate with each other. The 2.4GHz frequency is also used by most other modern home wireless devices that may be connected to your computer, along with various other electrical items such as hands-free telephones and wireless audio/video cameras and repeaters.
USB 3 devices naturally use cables but the electrical signals passed through them are scrambled at a constantly varying frequency. The noise produced by the devices and cables radiates from them and dissipates in the surrounding space.
Unfortunately the large range of high frequencies that USB 3 is allowed to use includes 2.4GHz, putting it in direct conflict with the Bluetooth signal you may also have in your room. This means that any USB 3 port, cable or device can emit frequencies that will cause interference to a Bluetooth device you are using in your computer.
If you want to know more and see some nice wave form diagrams you're in luck! Intel have made a white paper on the subject hidden deep within their website that you may want to refer to for a more detailed overview.
