Abstract
Security arrangements for a universal serial bus (USB) protocol stack of a USB host system are provided. The security arrangements prevent an unauthorized or suspicious USB device from communicating with the host system, detect suspicious activity originating from a device which is already communicating with the host system and may provide notification to a user.
