When I connect my usb cable from my Note 4 to my computer it doesn't recognised my Note 4. I have already installed the latest version of Kies 3 with samsung driver. I noticed when I first purchased my Note there was no problem but after updating the various updates, I am facing this problem. I have tried attaching the usb cable to two computers to test and still faced with the same problem. Anyone facing this problem after updating firmware? Any solution?
