Problems solved by technology

[0006] Because the USB universal driver on the terminal side is basically redirected according to a certain standard USB protocol specification, if the physical USB device is not designed according to this standard USB protocol specification, the physical USB device cannot perform correct operation according to the operation request message. redirection, and even the redirection cannot be realized according to the operation request message, which affects the normal use of the physical USB device by the user

Embodiment Construction

[0101] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0102] Before further explaining the embodiment of the present invention, the relevant background knowledge of the embodiment of the present invention will be introduced first.

[0103] Remote virtual desktop means that computing and storage resources are concentrated on a remote server (usually a data center). Through the remote desktop protocol, the interface of the remote virtual desktop is delivered to various local terminals (such as thin clients, desktop computers, portable computers, tablet computers, smart phones, etc.) for display. At the same time, it can map various input and output devices of the local terminal (such as: keyboard, mouse, USB peripherals, serial and parallel port peripherals, earphones and microphones, etc.)...

Abstract

The invention discloses a method, a device, a terminal, a server and a system for accessing a USB device, belonging to the technical field of computers. The method includes: receiving an access request issued by the server; judging whether the access operation indicated by the access request is the first access operation; if the access request indicates that the terminal performs the first access operation on the physical USB device, performing the same operation as the first access operation according to the compatibility policy The corresponding first processing operation, so as to feed back the execution result of the first processing operation to the server. Since the physical USB device does not support the actions performed by the terminal in response to the first access operation when the compatibility policy is set, even if the physical USB device is not designed according to a standard USB protocol specification, the physical USB device can still Correct redirection according to the access request solves the problem that some physical USB devices that are not designed according to a certain standard USB protocol specification cannot be redirected, and provides a guarantee for users to use physical USB devices normally.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method, device, terminal, server and system for accessing USB devices. Background technique [0002] Through the remote desktop protocol, the remote virtual interface provided by the remote virtual desktop system running on the server side is delivered to various local terminals for use by the users on the terminal side; at the same time, through the remote desktop protocol, various The physical peripherals are mapped to the remote virtual desktop system on the server side, and the virtual peripherals of the peripherals are displayed in the remote virtual desktop provided for the terminal side. Users can operate the virtual device on the terminal side to realize the control of the physical peripherals. operate. The remote desktop protocol involves the interaction between the terminal side and the server side, and the protocol is divided into different interactive service imp...
