USB device not recognized.
Some computers only recognize devices when they are plugged into the right usb ports. Have you tried using a different port? Also, some chords can be finicky, some of the cheaper ones don't like you when you try to do get into a device like that. Another thing you can try is to do like someone commented, and make sure you have the right driver for your device for your computer to recognize it. Just google search for the right driver for your model.
