Embodiment Construction

[0028] Such as figure 1 As shown, a cloud terminal USB redirection method includes steps:

[0029] S100: Initialize the libusb library and the usbredir library in the cloud terminal, and obtain the libusb instruction library and the usbredir instruction library.

[0030] The cloud terminal refers to a network device implemented by embedded ARM, on which the linux operating system runs, and has peripheral interfaces such as network VGA and USB. The main function is to connect the virtual machine (windows) on the virtualization server by running the spicec client, So as to realize the function of remote desktop. Here, the research mainly focuses on the cloud terminal of the linux operating system, initializes the libusb library and the usbredir library in linux, and obtains the libusb instruction library and the usbredir instruction library. To initialize the libusb library in linux, specifically, libusb_init may be called to initialize the libusb library.

Abstract

The invention provides a method and a system for redirecting a cloud terminal USB, wherein an libusb base and a usbredir base in a cloud terminal are initialized, a libusb command base and a usbredir command base are acquired, a callback function of usb hot drawing is bound according to the libusb command base, a usb redirection channel is defined, and the libusb command base and the usbredir command base are called, a usb device is activated, the callback function of the usb hot drawing is bound, the callback function is generated, a read-write callback function of the usb device is defined and usb redirection is realized when access of the usb device is detected in the usb redirection channel. In the whole course, the libusb base and the usbredir base in the cloud terminal are applied, and the USB redirection is realized quickly by adding the USB redirection channel and redirecting the channel to inherit a channel base type, so that user experience is enhanced.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a cloud terminal USB redirection method and system. Background technique [0002] USB device redirection is to redirect the operation of the device on the Linux server in the cloud terminal to the Linux terminal. The principle of USB device redirection is: the server creates a virtual device, and the operation on the device is sent to the terminal by the virtual driver through the network. After receiving the request, the terminal sends it to the USB device, and then returns the result to the server through the network. [0003] With the development of desktop virtualization technology, more and more companies and enterprises have begun to deploy desktop virtualization systems. During the deployment and application of the virtualized desktop cloud, the user needs the cloud terminal to redirect different USB devices to facilitate office work. [0004] However, for the current ...
