Aukru® Cable USB HOST / OTG Usb 3.0 For Samsung Galaxy Note Pro 12.2 / Samsung Galaxy Tab 12.2 pro / Samsung Galaxy Note 3 N9000 N9005 / Galaxy S5 (Electronics)
Small cable magic, I even tested my webcam (careful not need rooter your device, there are applications that work) Keyboard ok. I found something nice. Before having my tablet I had a 4G Galaxy S3 with a small camera to see the screen on a TV via HDM
