Equipment for controlling USB slave and receiving output information therefrom and implementation method thereof

Abstract

The invention provides equipment for controlling a USB slave and receiving output information therefrom and an implementation method thereof. The equipment is characterized by comprising a USB primary device port module, a power supply control module, a signal control module, a signal intercommunication module, a control module, a power supply and communication module, wherein the USB primary device port module is used for connecting an external USB slave; the power supply control module and the signal control module are used for controlling the power supply and signals of the external USB slave; the signal intercommunication module is used for constructing a special signal channel for controlling the external USB slave and receiving the output information therefrom; the control module controls the external USB slave through the power supply control module and the signal control module and communicates with the external USB slave through the signal intercommunication module; and the power supply and communication module supplies electric power and communication to the equipment. The embodiment of the invention is mainly used for providing the equipment for controlling the USB slave and receiving the output information therefrom and the implementation method thereof, which can be used for observing, debugging and testing the USB slave.

Description

technical field [0001] The invention provides a method for using a conductive shell of a USB port and a conductive component connected with the shell as a half-duplex communication line, and particularly relates to a device for controlling a USB slave device and receiving its output information and its implementation method. The field involved is the firmware development, debugging and use of USB slave devices. Background technique [0002] With the development of the Internet, more and more computer peripheral electronic devices have been developed and connected to the Internet. The easiest and most convenient way for these electronic devices to be connected to a computer is through a USB interface. USB is a universal serial bus that supports plug-and-play. It has the ability to link 127 devices on one cable, and its data transfer rate can reach 480Mb per second. It can also provide power to the device. [0003] All USB devices connected to the host have a built-in microc...
