The following is now actually almost a SGNote3 (Branding free, not rooted, Android 4.4.2) score ;-) - would be without the HUB not possible:
Have a test basis via USB mouse and keyboard (HP-standard desktop computer keyboard, VIVANCO With Cheap [6] mouse, both about 5 years old) connected.
To my surprise, have both been recognized immediately and were ready for use in time (!).
The Note3 can therefore operate perfectly:
Text input via keyboard in div. Apps (Office, Messenger, ...) 1A! All special characters (incl. Old-gr) are correctly interpreted.
With the mouse you can navigate super: Immediately after Aschluß appears on the display, a mouse pointer, which reacts smoothly and cleanly.
Scrolling with MMT-wheel (pressed or LMT hold) to scroll between screens (wipe).
Single-click to open folders and LMT applications, RMT-click she shoots back.
Scrolling in applications (browser, Office, ...) with MMT-site up / down also works.
Drawing (action memo, Scribmaster, ...) goes much leicher as even with the touch-pen own (but is vlt. Habit from the computer).
If all still have an HDMI HDTV Adapter on my flat screen TV works ...: -D
All in all, for me, a must-have extension and worth every penny !!!
