Data transmission bridging device as well as control chip and method thereof

Abstract

The invention discloses a data transmission bridging device as well as a control chip and a method thereof. The device transmits data by adopting a standard of a universal serial bus and comprises a first connecting interface, a second connecting interface and a control chip, wherein the first connecting interface is used for being connected with a first host machine terminal device, and the second connecting interface is used for being connected with a second host machine terminal device or a subordinate terminal device; and moreover, the control chip is connected with the first connecting interface and the second connecting interface, further comprises two transmission paths for detecting the device connected with the second connecting interface and transmits the data between the first connecting interface and the second connecting interface by switching and selecting one of the two transmission paths so as to achieve the aim of being convenient for the host machine terminal devices and other devices to bridge and transmits the data.

Description

technical field [0001] The present invention relates to a data transmission bridging device, in particular to a data transmission bridging device which adopts the specification of Universal Serial Bus (USB) and can be switched to bridge and transmit data of two host end devices, and its control chip and method . Background technique [0002] Due to the rapid development of science and technology, the penetration rate and utilization rate of computers have increased significantly. In addition, almost most of the data (including audio-visual, communication, document and other data) can be produced and processed by computers at present. Therefore, the amount of file data stored by users on computers will also increase day by day. [0003] In the case of an increase in the amount of data, relatively, data transmission becomes one of the actions that users often need to perform. In terms of long-distance data transmission, at present the most common way is to achieve the purpos...

Problems solved by technology

However, in this way, operations such as inserting devices, copying files, and pasting files must be performed on the two computer hosts separately to complete data transmission, and its transmission efficiency is relatively poor.

[0007] However, looking at the above-mentioned several short-distance transmission methods between computer hosts, although the transmission efficiency of the third transmission method is relatively poor, it is also one of the most commonly used methods by users at present.
