I am unable to operate normal on Windows 7 and MSI B450M motherboard, because:
1) Neither USB device working, including keyboard and mouse
2) Windows update doesn't help, because it says processor is incompatible (AMD Ryzen 2400G)
3) I can't run motherboard acompanying setup CD but unknown reason. First I thought this is because it's GUI can't work mousless, but later I activated keyboard mouse manipulation but still unable to click "Install" button. During load it says KB3033929 not found. I can't install this KB because it says "Unknown error"
Is it possible to install USB drivers separately?
Please don't suggest to install Windows 10, it is not an option.
