Abstract
The present invention relates to a method for automatic mapping and updating of computer switching devices, wherein the computer switching device is electrically connected with a plurality of peripheral devices and computers via a USB host MCU and a plurality of USB device MCUs that are connected. For non-standard USB devices or USB standard enumeration and parsing unable to be processed by built-in firmware, the USB host MCU transfers special requirements to a computer, receive and convert feedbacks, and transmit them to external peripheral devices to perform enumeration and connection processes and store them in the USB host MCU. For special communication requirements of computers, the USB device MCU performs a reverse process, and decides to map and update automatically to connect USB peripheral devices with computers successfully, thus increasing applicability of products, prolonging their service life and reducing consumption of resources for the benefit of environmental protection.
