Question with connecting third-party devices (Klava, mouse with usb interface) on the new OS?

Question

macOS

I immediately put a beta for macOS Big Sur developers, the first problem I encountered was that the mouse does not work! a long poppy launch, it unsticks the wifi for a long time, it doesn’t matter, when you start it in the password entry window, the mouse works, everything is ok, we already load the system, the mouse is locked, and after sitting for about 5 hours I found out that the program for the mouse (mi gaming mouse) is installed, it works, but the poppy in the protection and security section, auxiliary software is blocked, it is just connected with the mouse and I didn’t have time to screen and remember some more points. So, when you try to confirm their launch, it asks you to reboot the system, after which everything is new. After even longer manipulations and reboots, the notification about blocking additional software disappeared altogether. The main clue in this problem is that before entering the password, the mouse and keyboard work, the system boots, the devices die.
