Problems solved by technology

[0004] Whether the external device is connected to the port expander or directly connected to the computer, it can work normally. In principle, the user can choose to connect the external device to the port expander or the computer. The external device directly connected to the computer can be used by the computer The operating system recognizes the external device, and the operating system can display the name of the external device and the port location it is connected to. However, when the external device is connected to the port expander, the operating system can only display the external device, but cannot know whether it is connected On which port, although the external device can still work normally, when the user wants to know the connection status of each port of the port expander, he must confirm it by himself with his eyes and hands, which is really inconvenient

Abstract

The invention relates to a port expander with a connection identification function, such as a USB hub for connection with a computer or a dock of a portable computer. The port expander has a control unit and a plurality of input / output (I / O) ports. An application program corresponding to the port expander is installed to the computer. The control unit detects whether the I / O ports are connected to an external device, and reports a connection status of the I / O ports to the computer when the I / O ports are detected to be connected to the external device. The invention also relates to a method for identifying the connection status of the port expander coupled to a computer. The port expander with the connection identification function and the identification method of the invention are capable of monitoring the connection status of external devices on the port expander.

Description

technical field [0001] The invention relates to the technical field of personal computers, in particular to a port expander with a connection identification function related to a USB hub or a base of a portable computer and an identification method thereof. Background technique [0002] Universal Serial Bus (Universal Serial Bus, USB) is a standard specification for establishing a communication relationship between a computer system and multiple external devices, and is used to replace many existing serial ports and parallel ports. USB can connect multiple USB is a kind of external device, such as mouse, keyboard, digital camera, printer, multimedia player, flash drive and external hard disk, etc., and can plug and play (plug and play), so for many electronic devices, USB has become a must standard connection port. [0003] The dock is a base that connects the notebook computer to general peripheral devices. Since many peripheral devices do not yet have standard connectors,...
