Problems solved by technology

Therefore, if figure 1 and figure 2 The solution shown is only applicable to PCs that can be installed on the operating system and the complete USB host device class driver
[0006] And for such as image 3 The shown terminal USB device and the terminal USB host (non-PC) are integrated in the same embedded device. Since there are many types of embedded operating systems, which are not like the limited number of operating systems in the PC field, the terminal USB host The requirement that the same operating system as the remote USB host must be used is an unacceptable restriction for the embedded terminal

Embodiment Construction

[0070] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0071] In this embodiment, virtual USB devices that can interact through the network are respectively set on the far-end side and the near-end side, that is, both the remote virtual USB device and the terminal virtual USB device can realize the USB device function and the network access function, and the remote virtual USB The USB device emulates the terminal USB device to be accessed by the remote USB host, so that the remote USB host thinks that the terminal USB device is directly connected to the remote USB host, and then the remote virtual USB device passes through the IP network and the terminal virtual USB device. The remote USB host's access to the remote virtual USB device is mirrored as the terminal USB host's access to the terminal USB device, ...

Abstract

The invention discloses a virtual universal serial bus (USB) system, virtual USB equipment and a virtual USB method for realizing USB host remote access. The virtual USB equipment capable of performing network interaction is arranged on far-end side and near-end side respectively; the far-end virtual USB equipment simulates terminal USB equipment to be accessed by a remote USB host; and the far-end virtual USB equipment images the access into the access of the terminal USB host to the terminal USB equipment through an internet protocol (IP) network and terminal virtual USB equipment so as to realize the remote access of the far-end USB host to the terminal USB equipment across the IP network. The remote access of the far-end USB host to the terminal USB equipment does not require direct interaction between the far-end USB host and the terminal USB host, so the limit that operating systems must be consistent and drivers of the USB host equipment must be complete does not exist, and the generality of the remote access of the USB host can be improved.

Description

technical field [0001] The present invention relates to Universal Serial Bus (USB) technology, in particular to a virtual USB system for realizing remote access of a USB host, a terminal virtual USB device for realizing remote access of a USB host, and a virtual USB device for realizing remote access of a USB host. A remote virtual USB device and a method for realizing remote access of a USB host. Background technique [0002] According to the definition of the USB specification, the USB bus only supports point-to-point interconnection, and the transmission distance is limited. However, with the development of the USB technology, it has been possible in the prior art to enable the USB host to access the USB device through the network. [0003] Such as figure 1 As shown, the PC on the remote side of the IP network is used as the remote USB host, which can communicate with the IP network ("IP network" as described herein refers to any network that supports the IP protocol in...
