Abstract

The invention discloses a USB hardware virtualization method based on software simulation. The USB hardware virtualization method comprises the following steps: S1, when an operating system is started, automatically loading a USB host controller drive and a matched application program; s2, setting necessary parameters for a matched application program; s3, accessing USB hardware into an operatingsystem, and automatically virtualizing a plurality of USB virtual devices according to the information of the physical devices through a host control driver; and S4, identifying a plurality of USB virtual devices through an operating system and adding the USB virtual devices to the device list. According to the invention, the traditional USB device virtualization technology is improved, one deviceis supported to simultaneously virtualize a plurality of hardware devices with completely same functions, and 128 hardware devices with completely same functions can be supported at most, and each virtualized hardware device can work independently at the same time without mutual influence.

Description

technical field [0001] The invention relates to the technical field of USB hardware virtualization, in particular to a software simulation-based USB hardware virtualization method. Background technique [0002] USB hardware device virtualization is a common technology to solve the problem of using a USB hardware device connected to a host computer on other remote systems. The general implementation plan is to direct the USB device to other systems through the network, such as the virtual machine system running on the host, the cloud terminal system connected to the host, and other hosts in the LAN. Existing implementations such as USBRedirector, USBIP, etc. have been realized through the network, through the program installed on the host and the remote host, redirecting the USB device connected to the host to the remote system, without any special work on the remote operating system Configure to use the redirected virtual USB device. Contents of the invention [0003] Ai...
