Virtual machine system and unloading method of universal serial bus device thereof

Abstract

The invention provides a virtual machine system and an unloading method of a universal serial bus device thereof. The system comprises a host operation system HOS and a customer operation system GOS, which is characterized by also comprising a second USB drive module, a first orientation module, an event monitoring module and an event simulation module, wherein the second USB drive module comprises an unloading unit; the first orientation module orientates a second USB physic device to the second USB drive module, and the second USB physic device is of a device which is accessed through a docking station device and is required to be used in GOS; the second USB drive module uploads the second USB physic device which is orientated by the first orientation module as a second virtual USB device which is accessed through the docking station device; the event monitoring module transmits a notice to the GOS when detecting an unloading request of the docking station device; and the event simulation module produces an unloading command based on the notice for the second virtual USB device, and the unloading unit unloads the second virtual USB device according to the unloading command. The virtual machine system realizes the automatic processing of the unloading event of the docking station device in the virtual machine system.

Description

technical field [0001] The invention relates to the field of virtual technology, in particular to a virtual machine system and an unloading method of a universal serial bus device. Background technique [0002] However, due to the limited layout of the external interfaces on the host computer, once many external devices need to communicate with the host computer at the same time, there may be insufficient external interfaces. This phenomenon is particularly evident on notebook computers. [0003] In order to solve the above-mentioned problems, many computer hosts can now provide a docking station (Dock) interface through which extended external devices can be connected, wherein the external devices include USB (Universal Serial Bus, Universal Serial Bus) equipment. [0004] The operating system design also has a Dock device and a Dock device uninstall event processing mechanism. When pressing the Dock device uninstall button set on the computer, the operating system will a...

AI Technical Summary

Problems solved by technology

[0010] It can be seen from the above methods that in the first method, once the USB physical device is still used by GOS, the data in the USB physical device may be damaged, while in the second method, the user needs to perform multiple operations, which is very cumbersome
