I can plug an external-powered 4-port USB hub to Kiano Core 10.1 Dual 3G and it is recognized by the system and USB Device Info app. But as soon as I connect a gaming mouse or keyboard that simulates an USB hub (with mouse and keyboard attached to it so you can bind keys to mouse and clicks to keyboard), the system freezes and only unplugging the hub or waiting some time (if only keyboard is plugged to the hub) can help. After waiting some time, the system unfeezes and the app recognizes the keyboard. About the mouse, it completly freezes the system and only a hard reset helps.
On my Galaxy Note 3 and Xperia P, the hub, mouse and keyboard work without problems.
Both mouse and keyboard work with the tablet if plugged without the hub (mouse is recognized as both mouse and keyboard so I cannot use the on-screen keyboard, but this is another problem).
I have a rooted original rom.
Can anyone help with this?
EDIT: USB pendrives work on the powered hub. The problem may be considered solved, because I found another unpowered USB hub and both mouse and keyboard work on the unpowered hub.
