Abstract

The invention provides a USB bandwidth self-adaptive adjustment method for HID slave equipment. The method comprises the following steps: respectively registering a first bandwidth configuration corresponding to a USB1.1 protocol, a second bandwidth configuration corresponding to a USB2.0 protocol and a third bandwidth configuration corresponding to a USB3.0 protocol in a driver of the HID slave equipment; setting a plurality of levels of bandwidth occupation levels for the second bandwidth configuration, and setting a bandwidth value for each level of bandwidth occupation level; the HID slavedevice is connected with the upper computer according to a specified bandwidth value; judging the connection condition of the HID slave device and the upper computer, reducing to the next-level bandwidth occupation level or the next-level bandwidth configuration when the bandwidth resources are preempted by other slave devices to cause connection failure, and then connecting with the upper computer again; and when the HID slave device is successfully connected with the upper computer, ending the configuration. According to the method and the device, automatic adjustment of HID bandwidth resource occupation is realized, and resource preemption conflicts when the upper computer is connected with a plurality of HID peripherals are effectively reduced.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method, device, device and medium for adaptively adjusting the USB bandwidth of an HID slave device. Background technique [0002] With the rapid development of terminal equipment and the popularization of environmental protection concepts, more and more organizations are popularizing paperless office requirements on a large scale, improving business efficiency and reducing energy consumption. However, organizations need to ensure the security of user data and enterprise data at the same time, so most of them use drive-free USB to connect external terminal devices. [0003] Major terminal manufacturers currently adopt 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 uses the USB interrupt communication method, which requires the USB controller of the host computer ...
