Embodiment 1

[0038] This embodiment provides an adaptive adjustment method for the USB bandwidth of an HID slave device, such as figure 1 shown, including;

[0039] Step 10, respectively register the first bandwidth configuration corresponding to the USB1.1 protocol, the second bandwidth configuration corresponding to the USB2.0 protocol and the third bandwidth configuration corresponding to the USB3.0 protocol in the driver of the HID slave device;

[0040] Step 20, setting multiple levels of bandwidth occupancy levels for the second bandwidth configuration, and setting a bandwidth value for each level of bandwidth occupancy levels;

[0041] Step 30, the HID slave device and the host computer are connected according to a specified bandwidth value;

[0042] Step 40, judge the connection situation of the HID slave device and the host computer, when the bandwidth resource is preempted by other slave devices and cause the connection to fail, enter step 50; When the connection of the HID slav...

Embodiment 2

[0066] In this embodiment, an HID slave device USB bandwidth adaptive adjustment device is provided, such as figure 2 As shown, it includes: a protocol bandwidth registration module, a bandwidth occupancy level configuration module, a default connection module, a connection judgment module and an automatic adjustment module;

[0067] The protocol bandwidth registration module is used to respectively register the first bandwidth configuration corresponding to the USB1.1 protocol, the second bandwidth configuration corresponding to the USB2.0 protocol, and the third bandwidth configuration corresponding to the USB3.0 protocol in the driver of the HID slave device. ;

[0068] The bandwidth occupancy level configuration module is configured to set multiple levels of bandwidth occupancy levels for the second bandwidth configuration, and set a bandwidth value for each level of bandwidth occupancy levels;

[0069] The default connection module is used to connect the HID slave devic...

Abstract

The present invention provides a method for self-adapting USB bandwidth of a HID slave device. The method includes: respectively registering a first bandwidth configuration corresponding to the USB1.1 protocol and a second bandwidth configuration corresponding to the USB2.0 protocol in the driver of the HID slave device. The third bandwidth configuration corresponding to the USB3.0 protocol; multiple levels of bandwidth occupation levels are set for the second bandwidth configuration, and a bandwidth value is set for each level of bandwidth occupation level; the HID slave device and the host computer press a specified bandwidth value to connect; judge the connection between the HID slave device and the host computer, when the bandwidth resource is preempted by other slave devices and the connection fails, reduce it to the next level of bandwidth occupation level or the next level of bandwidth configuration, and then reconnect to the host computer; When the connection between the HID slave device and the host computer is successful, the configuration ends. The invention realizes the automatic adjustment of HID bandwidth resource occupation, and effectively reduces the resource preemption conflict when the upper computer connects multiple HID peripherals.

Description

technical field [0001] The present invention relates to the technical field of computers, and in particular, to a method, apparatus, device and medium for adaptive adjustment of USB bandwidth of an HID slave device. Background technique [0002] With the rapid development of terminal equipment and the vigorous popularization of environmental protection concepts, more and more organizations are popularizing the demand for paperless office on a large scale, improving business efficiency and reducing energy consumption. However, organizations also need to ensure the security of user data and corporate data, so most of them use drive-free USB to connect external terminal devices. [0003] Major terminal manufacturers currently use the most effective and safe USB drive-free method, and basically use HID communication to report terminal device attributes to the host computer. The HID device adopts the USB interrupt communication method, which requires the USB controller of the ho...
