Public bug reported:

Hi to all.
I have a convertible laptop from Acer. Spin 5 SP513-52N
I Have a Wirele Mouse. Xiaomi MI Mouse. It Works both with wireless dongle and 
with bluetooth. 
With dongle all is ok.
With bluetooth:
a) On Windows it works good;
b) ON Android it works good;
c) On linux, various distro (ubuntu, debian, Openasuse, Mint, Majaro, Cromium 
OS), my PC Doesn't see my mouse. 

It's strange.
