If there still isn't enough distance between the USB Bluetooth adapter and the USB 3 ports and devices on your computer than a great solution is to place the USB Bluetooth adapter far away from the computer itself.
Here a USB Bluetooth adapter has been extended by placing it on the end of a USB extension cable. This has been placed on the top of the monitor, far away from any interference caused by the external USB 3 hard disk
Luckily USB extension cables exist and this will allow you to put a lot of distance in-between the computer and Bluetooth adapter that we recommend you attach to the end of the USB extension cable.
On a typical desktop computer setup you could run the USB extension cable along your desk or up behind your monitor. It can then sit out of the way and far away from the troublesome USB 3 ports! This solution may not be that practical for a laptop that you constantly travel with but for a desktop or fairly stationary laptop it's a great solution.
Remember to plug the extension cable into a port as far away from the USB 3 ports as possible.
The slightly more expensive option
If you're running out of USB 2.0 ports another option is to buy a USB 2.0 hub. Try to get one with a long USB cable (around a meter or more) to separate it from the computer as far as possible. Now plug your USB Bluetooth adapter into the new port and make sure you plug the USB hub into a port on the computer as far away from the USB 3 ports as possible.
