I have a Samsung Galaxy Tab Pro (SM-520). It has been working perfectly. Now, all of a sudden, when I plug in the usb cable, it does not show up in the "My Computer" section of my Windows 7 system. It gives the familiar "ding" sound when I plug it in, and it charges using the same cable, but now I cannot drag files across to it anymore. Ideas?
If you have Kies and Android File transfer both installed, they can conflict. I just forget which is better to use
In Kies menu drop-down there should be an option to re-install the drivers, also make sure your tab is in mtp mode. John.
