So I'm having issues when connecting my Samsung s5 to my pc for file transfers. When I go to transfer files it just hangs and won't allow me to transfer any files. I tried using other usb cords and even the one that came with the phone but it still does the same thing! Now whenever I go to my secondary computer any usb cord I use works perfectly fine and connects immediately, wth?! My main pc is using win 8.1 and my secondary pc using win 7. Please help me figure out what the issue is! Thanks
