Embodiment Construction

[0036] In order to effectively solve the problem that a plurality of personal computers switch to use a plurality of USB devices, and because all USB devices must be connected to the personal computer (PC) using the USB device through a hub, the present invention utilizes this Features, provide a hub with multiple upstream ports, and select which one to use the hub through the conversion controller built in the hub and the control software in individual PCs, and control and use the USB device connected to the hub, Its related description will be discussed in detail below.

[0037] refer to Figure 5 , Figure 5 Shown is a connection schematic diagram of a computer system that uses a USB hub with multiple upstream ports and can switch between different computer hosts according to a preferred embodiment of the present invention.

[0038] The components of the computer system of the present invention mainly include a plurality of personal computers 40a-40n, a plurality of USB d...

Abstract

The invention relates to the USB concentrator and the computer system that uses the said USB concentrator. The USB concentrator possesses multiple ports for the upper course and these ports can be switched between different host computers. Based on the requests of different host computers or the selections of manual switching, the right of use is switched to the host computer, which needs to use the USB concentrator, in due course. Thus, it makes the host computer possible to control the data access on the USB devices connected to the ports on the lower course of the USB concentrator. The selected switch of the host computer can be controlled by computer software in the invention, the autoamtic switched function can be realized. Moreover, the software can determine whether the USB devices being used are allowed to switch or not so as to prevent the application functions from influence caused by incorrect switch.

Description

technical field [0001] The invention relates to a USB hub, in particular to a USB hub which has multiple upstream ports and can be switched between different hosts and a computer system using the USB hub. Background technique [0002] Since IBM developed PC XT and PC AT personal computers, personal computers compatible with IBM PC have been widely used all over the world. During this period, due to the advancement of semiconductor technology, the functions of personal computers have become more and more powerful, and more and more devices are available at the same time. Printers are almost necessary for printing out data. With the development of the Internet, users at home need to use modems to connect to the Internet. In order to avoid computer crashes and the work results being lost, it is necessary to prepare a large-capacity backup device for regular backup. data. Scanners are also commonly used if you want to save graphics to your computer. [0003] The above-mention...
