However, in practical applications, some applications in the terminal will also use the physical USB device inserted into the terminal. For example, there is program 1 in the user mode of the terminal, and program 1 also needs to use the physical USB device. At this time, the current The kernel driver bound to the USB physical device is forcibly unbound. If the driver bound to the current USB physical device is the general driver used in the redirection process of the USB client, the redirection process will be interrupted, causing the physical The USB device cannot be properly mapped to the server with the remote virtual desktop system, resulting in the application in the remote virtual desktop system not being able to normally call the input and output devices of the local terminal

A method and apparatus for establishing device mapping, which relate to the technical field of electronic information, enable the mapping between a physical device and a virtual device not to be broken, and ensure that an application in a remote virtual desktop system can normally use the physical device without being interrupted. A client acquires identification information of a physical device (101); and after a first application program identifies the physical device according to the identification information, the client changes a first state of the identification information into a second state (102). The method and the apparatus are applicable to a remote desktop system.
Description
technical field [0001] The invention relates to the technical field of electronic information, in particular to a method and device for establishing equipment mapping. Background technique [0002] At present, various input and output devices of the local terminal, such as: keyboard, mouse, USB (Universal Serial Bus, universal serial bus) peripherals, earphones and microphones, etc., are usually mapped to remote virtual desktop systems through the remote desktop protocol. server. [0003] In the prior art, the remote virtual desktop system requires at least two hardware devices, a client computer and a server, during operation. The software program used to realize the remote virtual desktop system can be called a server. The client computer accesses the server with the remote virtual desktop system through the client running on the client computer, and invokes the input and output devices of the client computer through the remote virtual desktop system. For example: if f...
