Try this.
1. Go to Storage in the Settings menu.
2. Open the options , there should be one that says USB computer connection
3. While the device is connected to your computer, Check the Media device (MTP) option.

5. Select MTP and you should probably be able to read your device on your computer now,
AND it shouldn't make a difference what cable you are using.
