Hello,
I just bought a raspberry pi 3 with xiaomi controller pad and I can figure out why the xiaomi controller pads aren't detected by the raspberry (not working with iOS too, but working great with android).

Bluetooth : https://www.amazon.fr/gp/product/B014L88D64/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1
Don't hesitate if you have any questions or clues..
Thanks
Here are the dmesg & /recalbox/scripts/recalbox-support.sh

I understand french and english so don't hesitate to speak french if you prefer
The problem came from the detection of the bluetooth dongle -> bad contact with the raspberry.
