First of all, you need to install the correct driver versions on ALL devices (you have two unknown ones in the device manager). It is best to download drivers from the official website of the device manufacturer for a specific operating system (if USB, then this is the motherboard, chipset drivers, USB 3.0). The little utility cpu-z works well for determining the exact model of the motherboard .
There is an easier way - automatic installation of drivers from driverpacks, I have been using SamDrivers for a long time , it rarely fails, but it still happens.
