Midknyte, for the keyboard, it says "Bluetooth Connection 【 NOT INCLUDED BLUETOOTH DONGLE 】". I suppose that means that it does not require a dongle to communicate with the keyboard?

Would any brand micros USB hub OTG cable be fine such as the one in link below or are some brands better than others?
