Have you tried the USB ports on the back of the PC? If so....
Maybe try updating the drivers for the motherboard of your PC instead of using standard Windows 8.1 drivers. Assuming Windows 8.1 is recognizing all the USB ports you are trying to plug your cable into.
If this does not work and you have a copy of Windows 7, download Virtualbox and install Windows 7 as a virtual machine. Launch it make sure you have the USB settings inside the virtual machine setup to allow the USB to be used from Host PC.
Load the Samsung drivers in the Windows 7 virtual machine. I'm assuming those are the drivers you have stated you have downloading and reinstalled.
