I have Xiaomi Gaming laptop (gen 3, RTX2060, win10) and it does not load if mouse is plugged in (may be it will eventually load, but I waited for several minutes, only mi logo appeared, normally it loads in several sec). Can not access bios either. Usb devices loading is disabled in bios. Tried changing poling rate - did not help.
Otherwise if mouse is plugged in after windows loading, it works just fine. Other usb devices do not cause such problems (I do not have another Z though).
I use latest drivers and firmware (not beta).
I will try some additional testing with another laptop/mouse, but may be some one has faced that and can help me in advance.
