Embodiment approach

[0046] In an optional implementation manner, after determining the target USB device to be shared based on the above step S106, the USB processing terminal can also be specifically simulated as the USB device that Host0 wants to share, so as to provide subsequent Host0 through the USB processing terminal The device controls or occupies the target USB device, that is, performs business data interaction, and pre-builds a data transmission link between Host0 and the target USB device. For ease of understanding, an embodiment of the present invention provides an implementation manner of simulating a USB processing terminal as a target USB device inserted into Host0, including the following steps:

[0047] In step (1), the level of the USB bus is adjusted, and the preset control module in the USB processing terminal is simulated as a USB slave device mounted on the first USB host.

[0048] During specific implementation, the USB processing terminal will set the USB-P directly conne...

example 1

[0063] Example 1: In the application scenario of a centralized control device, such as a KVM (Keyboard Video Mouse, keyboard video mouse) controller scenario, the USB packet processing module can be configured in the KVM controller to make a set of HID devices at the operation end Multiple PC computers can be controlled in time-sharing and in different regions.

example 2

[0064] Example 2: In the application scenario of a distributed KVM control system, the distributed KVM control system includes a KVM signal sending terminal, a KVM signal receiving terminal, a KVM signal receiving device and an HID device. Among them, the KVM signal sending terminal is used to connect the signal source device, encode the video signal of the signal source device, and transmit it to the downstream receiving terminal through the public network; the KVM signal receiving terminal is used to receive the network signal and decode it It is a video format signal, and then pushes the video signal to the display device according to the pre-configured video signal display strategy; at the same time, the KVM signal receiving device collects the control commands sent by the HID device, and transmits them to the upstream KVM signal sending through the public network The terminal is further transmitted to the signal source device for remote control of the signal source device....

Abstract

The present invention provides a USB device sharing method, device and system, which relate to the field of communication technology. The method is applied to a USB processing terminal and includes: receiving a sharing request sent by a first USB host; wherein, the sharing request carries one or more a device descriptor; search for descriptor information that matches the device descriptor from the preset descriptor information storage area; the descriptor information storage area stores information corresponding to a plurality of USB devices mounted on the second USB host Descriptor information; based on the found descriptor information, determine the target USB device to be shared. The invention can improve the control efficiency of the USB device.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a USB device sharing method, device and system. Background technique [0002] According to the USB (Universal Serial Bus, Universal Serial Bus) transmission protocol, the data transmission of external USB devices such as mice and keyboards must be initiated by the host device during the enumeration phase and business phase, and a USB device can only be used by the host device at the same time. A host device occupies or controls. [0003] At present, the USB device is usually directly plugged into a specific interface of a host device. If another host device wants to use the USB device, the USB device can only be pulled out from the aforementioned host device, and then plugged into the aforementioned host device. another host device. Especially when the two host devices are arranged far away, it is very inconvenient to frequently plug and unplug the USB device, whi...
