-NV57H:~$ adb devices
List of devices attached
And I have done a search, where some people were having trouble using certain cords, mainly with Samsung devices, and switched cords with success. This does not apply in this situation as I have used adb many times with the cord I'm using, and also I did try to switch cords anyways.
