Abstract
Abstract A switch for connecting a peripheral device to a downstream USB device includes a plurality of peripheral interfaces operably connectable to respective peripheral devices; a USB downstream interface operably connectable to the downstream USB device, where the downstream interface is adapted to simulate insertion and removal of an upstream USB device; and a switcher for selectively establishing communication between a desired peripheral interface and the USB downstream interface.
