Abstract: The present invention relates to a system and method for switching keyboard and mouse devices and video displays, as well as USB peripheral devices, between USB hosts and video sources over extended distances. Provided is a distributed KVM and peripheral switch where a USB keyboard and mouse is emulated to the host interfaces of the KVM and peripheral switch and a USB host is emulated to keyboard and mouse interfaces of the KVM and peripheral switch. In addition, the keyboard, mouse, display and peripheral devices are separated from the hosts and video sources by a non-USB communications channel.

Abstract: The present invention relates to a system and method for switching KVM and peripheral interfaces between host interfaces. Provided is a KVM switch where a keyboard and a mouse are emulated at host interfaces of the KVM switch and hosts are emulated at keyboard and mouse interfaces of the KVM switch. In addition, the KVM switch provided is capable of switching, either independently or concurrently with a keyboard and mouse, additional peripherals, such as USB peripherals.

Abstract: The present invention relates to a system and method for extending USB connections. Provided are both active USB extenders and passive USB extenders that include functionality for accepting both standard and/or non-standard USB commands. The passive extender functions on a USB communications channel and the active extender functions to extend USB communications over a non-USB communications channel. Both types of extenders are configured to handle non-standard USB commands, such as a Macintosh power-on command or a Sun Microsystems reset, suspend, or wake-up command.
