First and foremost is obvious rule out possible causes of the problem:
- Make sure the cable is securely connected to the computer / smartphone: sounds silly but it can happen to us all.
- Try another cable: cable may have stopped working for some reason.
- Try another USB port on your computer: It is possible that the USB port on the computer to malfunction. If you only have a USB port try to use another device on the same port to see if it recognizes.
Also try to reboot both your PC and your phone, there may be a fault to be cleared with this.
