Default Iconbit Toucan Stick 3d Pro

Hi, guys. I just got Iconbit Toucan Stick 3d Pro, and its pretty great except that it doesnt supprot my logitech k400 keyboard w/touchpad. It uses a logitech unifying reciever, which is detected in system as usb device, but not used as a hid one. It is supported on another android media player of this brand - iconbit nano 4k - works flawless.

So, I have two questons:
1) Is there a way to solve this problem?
2) Is this device is just branded chinese stick, so i can find compatible newer firmware? Im not even asking about cyanogen)

Iconbit Toucan Stick 3d Pr uses Allwinner A20 cpu.
