and all connected systems are maintained 100% of the time, even as a user switches between the KVM ports. This makes generic device emulation unnecessary as the DDM allows each connected computer system to believe all connected I/O devices are remaining connected even as the

might move to another port. With Reverse DDM, an administrator can provide port level management control. Individual USB ports can be limited, configured, or assigned to specific kinds of devices. This adds a level of security in certain environments that require no USB thumb drives to be used, or printers connected, etc.
