Embodiment 1

[0046] see figure 1 , figure 1A flow chart of the first USB device redirection method provided by Embodiment 1 of the present invention is shown. figure 1 The redirection method of the USB device in is applied to the server comprising the virtual machine module, and the redirection method of the USB device comprises the following steps:

[0047] Step 110, responding to the redirection configuration request for the USB device, acquiring redirection configuration information for the USB device.

[0048] In this embodiment, the server is a server of the cloud desktop system, and the virtual machine module is a module for running a qemu (QuickEMUlator, quick emulator) process. At the same time, the cloud desktop system also includes a client device. After the client device establishes a communication protocol with the server, the client device can access the virtual machine module in the server. Client devices include human-computer interaction devices such as monitors, mice, a...

Abstract

The embodiment of the invention discloses a redirection method and device for USB equipment, computer equipment and a medium, the redirection method for the USB equipment is applied to a server comprising a virtual machine module, and comprises the following steps: responding to a redirection configuration request for the USB equipment, and obtaining redirection configuration information for the USB equipment; writing the redirection configuration information into a pre-stored configuration file, and sending a prompt signal to the virtual machine module; triggering the virtual machine module to analyze the redirection configuration information; and changing the redirection configuration of the corresponding USB equipment according to the redirection configuration information. And the server writes the obtained redirection configuration information into a pre-stored configuration file, triggers the virtual machine to analyze the redirection configuration information, and changes the redirection configuration of the corresponding USB device. The redirection configuration of the USB equipment is dynamically changed in the operation process of a network system.

Description

technical field [0001] The invention relates to the communication field, in particular to a USB device redirection method, device, computer device and medium. Background technique [0002] Cloud desktop, also known as desktop virtualization, is a technology that virtualizes components such as processors, memory, and hard disks included in terminal devices in back-end servers. In a cloud desktop usage scenario, in order to meet the usage requirements of different USB (Universal Serial Bus, Universal Serial Bus) devices, the cloud desktop system is usually configured with a USB device redirection function. Establish a connection between the user's local physical USB device and the virtual USB device in the server virtual machine, so that the physical USB device can be accessed in the cloud desktop system. [0003] However, during the operation of the cloud desktop system, if the connection interface drifts, the data packet size is abnormal, etc., the USB device cannot receive...
