Have a Verizon 4.4.3 Galaxy S4 using the standard cable. When I connect to the PC, the PC doesn't show it in explorer. The phone doesn't bring up the connection notification. I have enabled/disabled developer options. Re-installed the drivers. Tried different USB ports. In the end all it does is charge. I know this worked before as I have done it before, but this was before many updates ago.
The reason I need this is for debugging an android application I am developing.
