My new PC having windows 8.1 does not recognize Samsung galaxy tab pro connected via USB cable. What to do? I've tried different cables and different USB ports. It does not appear in Windows device manager. It only pops-out a window saying "The last USB device you have connected to the PC malfunctioned and Windows does not recognize it". I have not installed any drivers for the tab. I need just to copy files from PC to tab (music, movies...).
Thanks for help.
