Embodiment Construction

[0012] The specific implementation method of the present invention will be described below through an example of a 3G USB wireless network card.

[0013] According to the use function of the USB network card, it is required to:

[0014] 1) When the USB network card (device) is plugged into the host and starts, it must be able to determine the operating system of the host.

[0015] 2) Implement different follow-up functional behaviors according to different host operating systems.

[0016] According to the inventive method, as shown in Figure 1, the judgment process of the host operating system using the network card of the inventive method is:

[0017] 101 Insert a USB (network card, other devices are similar) device into the USB port of the computer host, and the USB device must report itself as a CDROM device. The process includes 1) when the device responds to the host's acquisition configuration command, it returns an interface. Configuration descriptor, the interface ty...

Abstract

A method for judging a host operating system through a USB embedded device comprises the steps as follows: 1), the USB device is taken as a standard USB mass storage device CDROM (compact disc-read only memory) for enumeration, that is, in an enumeration process, the device serves as a mass CDROM device to report the information to a host; 2), the USB device is inserted into the host, whether a seventh byte is 0x08 is judged when the USB receives a first SETUP package enumerated by the host, if yes, the host operating system is an Apple system, and otherwise, a subsequent step 3) is continued; and 3), when the USB receives the SETUP package for configuring the device by the host, whether the host requests a manufacturer character string descriptor is judged, if yes, the host operating system is Linux system, and otherwise, the host operating system is a Windows system.

Description

technical field [0001] The invention relates to computer mainframe technology in the information field and embedded USB device technology. Background technique [0002] USB (Universal Serial BUS) technology is used to standardize the connection and communication technology between computers and external devices. Its plug-and-play and hot-swappable features are favored by many product manufacturers. Most of various electronic devices provide a USB interface for communicating with a host computer to complete related product functions of the device. There are many kinds of computer operating systems, and traditional microcomputers mainly include Windows system, Linux system and Apple system. The recent popular handheld tablet PCs mainly use the Apple system and the Android system. The host of the USB embedded device can be a microcomputer or a tablet computer. The diversity of the host and the operating system sometimes requires the device to determine which operating system...
