However, if the multi-system terminal devices are connected by the traditional USB connection to the host, when the multi-system terminal devices switch between the front and back of the system, the host cannot recognize the function of the USB device in the foreground system after the switch. Therefore, a running The implementation scheme of connecting multi-system terminal devices to the host, when the multi-system terminal devices are connected to the host through USB, it can identify the USB device function of the corresponding system

The invention provides a scheme operating multiple systems and enabling a slave device to be connected and accessed into a master device by a USB (Universal Serial Bus). By a USB device function provided by a system kernel of the slave device, the slave device is connected and accessed into the master device by the USB; a connection event is sent into a random system matched with the USB device function provided by the system kernel of the slave device; and then the connection event and interactive data with the master device are processed by a USB device function in the random system. By the scheme of the invention, a gap of no solution which aims at multiple systems and enables the slave device to be connected and accessed into the master device by the USB in the prior art is filled. A kernel USB setting function is correspondingly set by the USB device function of each system in the slave device, and different USB device functions can be provided according to different systems in the slave device so as to further accord with the actual use requirements of users, thereby improving use experience of the users.
Description
technical field [0001] The present invention relates to the field of computer technology, in particular, the present invention relates to a method and a device for connecting a slave device running multiple systems to a master device through a USB connection. Background technique [0002] With the development of the times, various emerging operating systems continue to emerge, bringing users a novel and more convenient terminal experience. When a traditional single-system terminal device is connected to the host through USB, the host will perform corresponding identification according to the USB function set in the single-system device. Image Transfer Protocol) or Massstorage (mass storage), etc. However, if the multi-system terminal devices are connected by the traditional USB connection to the host, when the multi-system terminal devices switch between the front and back of the system, the host cannot recognize the function of the USB device in the foreground system after...
