Need HELP ASAP. I can't get my Nexus 5 to access my internal storage when I connect it with USB on my Windows 8. PC makes a sound when I connect usb, but I can't see my Nexus 5 in "This PC". Device Manager is also not showing anything related to my droid. Restarted both Nexus & Windows. I'm using the same original cable that came out of box with nexus. Please help. It was working fine like 2-3 days ago.
