AI Technical Summary

Technical Problem

Existing USB sharing devices have low data transfer efficiency, requiring software programs to intercept, identify, and process each communication command. This process is cumbersome and cannot fully utilize the high-speed configuration and performance of computers.

Method used

By establishing a one-to-one correspondence between the download USB endpoints on one side and the upload USB endpoints on the other side in a USB sharing device, and leveraging the multi-endpoint characteristics of USB manufacturer-defined categories of devices, shared data can be directly transmitted without packet processing and command recognition, achieving efficient data transmission through a transparent transmission method.

Benefits of technology

It improves the transmission efficiency of USB shared data, avoids intermediate identification and packet processing steps, and realizes efficient data transmission directly to the destination, adapting to the needs of efficient data sharing in multi-computer office environments.

Abstract

Disclosed are a USB sharing apparatus and a transparent transmission method therefor. The USB sharing apparatus establishes a correspondence between a USB downstream endpoint on one side and a USB upstream endpoint on the other side; pipe endpoints are defined, wherein the pipe endpoints receive shared data transmitted downstream by a first computing apparatus, and different pipe endpoints are designated based on an intended use of different shared data; and according to the correspondence, the shared data is transmitted from the pipe endpoints to the USB upstream endpoint on the other side, and the shared data is transmitted to a second computing apparatus by means of the USB upstream endpoint on the other side. The present invention achieves a shared data transparent transmission effect, and has high transmission efficiency and strong scalability.
