Embodiment 1

[0052] Such as figure 1 As shown, the USB device operating mode switching method of the present embodiment includes:

[0053] Step 101: Insert the USB device into the host, the USB device is configured with single-disc device information and at least one working mode information, the USB device sends the single-disc device information to the host, and the single-disk device information includes a host installation function Information about the installation of the management module;

[0054] Step 102: The USB device selects a working mode information and configures it as the currently effective working mode according to the configuration command issued by the host function management module.

[0055]According to the provisions of the USB protocol, multiple configuration descriptors (configuration descriptors) can exist on the device at the same time, but only one set of configurations is valid at the same time. When the USB device is inserted into the host, the operating sys...

Embodiment 2

[0081] This embodiment proposes a USB device corresponding to the working mode switching method of the USB device in Implementation 1, such as Figure 4 As shown, the USB device of this embodiment includes: a USB configuration module and an instruction receiving module;

[0082] The USB configuration module is used to configure single disc device information and at least one working mode information after the USB is inserted into the host, and send the single disc device information to the host;

[0083] The single disc device information includes the installation information for the host to install the function management module;

[0084] The instruction receiving module is used to receive the configuration instruction issued by the host function management module;

[0085] The USB configuration module is also used to select a working mode information to be configured as the currently effective working mode according to the configuration instruction.

[0086] The above-ment...

Embodiment 3

[0094] In this embodiment, the method, device, and system of Embodiment 1 above are used to switch the function of the USB device; in this embodiment, the USB device is connected to the host, and the multi-configuration feature of USB is used to switch the function of the device. After connecting the USB device to the host, first report the single CDROM status, and the function management software in the host decides whether to issue instructions and force the system to refresh the device management module. Specifically, take the USB device switching from single-disc mode to multi-port mode as an example, as shown in Figure 7 Shown:

[0095] Step 301: After the device is inserted into the host, the USB configuration module generates a variety of USB working mode information and first reports the single-disc CDROM device information, and the application management module initializes and makes all necessary application layer modules in a ready state, wherein the single-disc dev...

Abstract

The invention discloses USB (Universal Serial Bus) equipment, a communication system and a working mode switching method thereof. The USB equipment working mode switching method comprises the steps: USB equipment is plugged into a host, wherein the USB equipment is configured with single-disk equipment information and at least one working mode information; the USB equipment sends the single-disk equipment information to the host, wherein the single-disk equipment information comprises installation information by virtue of which a functional management module is installed on the host; and the USB equipment selects one working mode information to be configured as a current effective working mode according to a configuration instruction issued by the functional management module of the host. The USB equipment, the communication system and the working mode switching method thereof, disclosed by the invention, can be used to prevent the USB equipment from adopting power interruption and other manners to configure firmware program again to realize the switching of working modes, so that the time of switching the working modes is reduced.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a USB device, a communication system and a working mode switching method thereof. Background technique [0002] Many USB multifunctional devices currently on the market have a switching process from the optical disk to the multi-port working mode. When there is no UI (user interface, user interface) program and driver installed on the host (host), after the USB device is connected to the computer, it will first report a single-disc CDROM device information, which contains the device in multi-port mode. Required UI programs and drivers. After the installation process is over, the UI or the driver will automatically detect the USB device and send a specific command to switch the USB device from the CD to the multi-port working mode. [0003] At present, this general scheme has the following principle defects, namely: [0004] (1) Regardless of whether the UI and driver hav...
