Universal serial bus interface system and method

摘要

A system for reconfiguring a peripheral device having a first configuration connected by a computer bus and a port to a host computer. The system comprises a first circuit and a second circuit. The first circuit may be configured to download information for a second configuration from the host computer into the peripheral device over the computer bus. The second circuit may be configured to electronically simulate, over the computer bus, a physical disconnection and reconnection of the peripheral device to reconfigure the peripheral device to the second configuration.
