ELECTRONIC APPARATUS PROVIDING REAL-TIME SWITCHING AND SHARING OF USB ELECTRONIC DEVICES AMONG HOSTS

摘要

The present disclosure provides an electronic apparatus that comprises a number of Universal Serial Bus (USB) device control modules, a microprocessor, a priority arbitration module, a USB host control module and a USB hub module. The USB device control modules are configured to receive from and send to a host a USB electric signal. The microprocessor is configured to generate a number of virtual USB hub modules in a memory. Each of the virtual USB hub modules is configured to generate a USB device enumeration signal, in response to an electric connection status between a USB electronic device and the USB hub module, and to send the USB device enumeration signal via a corresponding one of the USB device control modules to the host. The priority arbitration module is configured to, in response to the availability of the USB electronic device, transmit the USB electric signal issued from the host to the USB electronic device via the USB host control module and the USB hub module.
