Hello. For some time I having this issue of random disconnect of USB devices (keyboard, mouse). One PC disconnects mouse after boot (only partially - scrolling is still working) - disconnecting and reconnecting USB mostly repair this. Other PC (notebook) have connected new keyboard and mouse which randomly disconnects like this:
