Why is my USB device not working?

The first thing you can do is check if the USB device is functioning on other devices.

If so, this narrows it down to either the USB port or your machine. 

Windows:

The first time you use a USB device it may need to auto-install drivers to allow it to work efficiently, preventing you from being able to use it straight away.

Similarly, you should check to see if there is an updated version of your USB driver.

Quite often these updates fix a number of these errors relating to hardware, making it very likely that it will resolve problems that you’re having with your USB. 

Mac:

If the USB device isn’t working, make sure it’s plugged to your computer correctly, it’s plugged into a power outlet if it has a power cord, and the necessary software is installed.
