Technical field
The present invention relates to a kind of PC technical field, relate in particular to a kind of port expander and the recognition methods thereof with linkage identification function relevant with the base of usb hub or portable computer.
Background technology
USB (universal serial bus) (Universal Serial Bus, USB) be a kind of standard specification of between computer system and a plurality of external device (ED), setting up correspondence, and in order to replace many existing serial ports and parallel port, USB can connect multiple external device (ED), such as mouse, keyboard, digital camera, printer, multimedia player, Portable disk and external hard drive etc., but and plug and play (plug and play), therefore for many electronic installations, USB has become indispensable standard connectivity port.
Base (dock) provides the pedestal that notebook computer connects general peripheral device, because many peripheral devices not yet possess AN connector, therefore base itself also can't standardization, and must cooperate actual needs and change design, base disposes a plurality of USB port, DVI port, HDMI port and audio port etc. usually.On the other hand, usb hub is to provide specially a plurality of USB port connecting more USB device, and does not possess other port.Therefore above-mentioned base and usb hub can be collectively referred to as port expander (port expander).
No matter external device (ED) is connected to the port expander or directly connects on computers, all can work, in principle, the user can select arbitrarily external device (ED) is connected on port expander or the computer, the external device (ED) that directly is connected to computer can be identified by the operating system of computer, operating system can show the title of this external device (ED) and the port position that connects thereof, yet when external device (ED) is connected the port expander, operating system only can show this external device (ED), but can't learn it is to be connected on which port, although this external device (ED) still can work, wish to get the connection status of knowing its each port of port expander as the user, must confirm voluntarily by its eye and hand that then inconvenience is arranged in fact.
Summary of the invention
The objective of the invention is to be to provide a kind of port expander and recognition methods thereof with linkage identification function, it can monitor the connection status of external device (ED) on the port expander.
For reaching above-mentioned purpose, port expander provided by the invention comprises control module and a plurality of input/output end port, whether control module is detected each input/output end port the connection external device (ED), and when input/output end port has external device (ED) to connect, the connection status of input/output end port is reported to computer.
The present invention provides a kind of recognition methods of the connection status to the port expander that is connected to computer in addition, and it comprises the steps: to provide a plurality of input/output end ports at the port expander; Application program corresponding to the port expander is installed on computers; Whether detecting has external device (ED) to be connected to input/output end port; Identification is connected to the external device (ED) of input/output end port; Report the connection status of input/output end port to the application program of computer; And the connection status and the external device (ED) that show input/output end port.
Whether the present invention detects each input/output end port by control module the connection external device (ED), if have, then identify external device (ED), and to the connection status of the application program of computer report input/output end port and show connection status and the external device (ED) of input/output end port, thereby realized the outer connection status of deploying on the port expander of monitoring.
Above-mentioned explanation only is the general introduction of technical solution of the present invention, for can clearer understanding technological means of the present invention, and can be implemented according to the content of instructions, and for above and other objects of the present invention, feature and advantage can be become apparent, below especially exemplified by preferred embodiment, and the cooperation accompanying drawing, be described in detail as follows.
Description of drawings
Fig. 1 is the connection diagram of port expander of the present invention and computer.
Fig. 2 is method flow diagram of the present invention.
Fig. 3 is connection status display window synoptic diagram of the present invention.
Embodiment
Reach technological means and the effect that predetermined goal of the invention is taked for further setting forth the present invention, below in conjunction with accompanying drawing and preferred embodiment, the port expander with linkage identification function and its embodiment of recognition methods, method, step, structure, feature and effect to foundation the present invention proposes are described in detail as follows.
Please refer to Fig. 1, it is the connection diagram of port expander of the present invention and computer, as previously mentioned, the port expander can be usb hub or the base of the USB port of providing (dock) is arranged, this port expander can be connected to the computer 2 with a plurality of USB port 5-7, this computer 2 can be notebook computer or desktop computer, and this port expander 1 comprises control module 10 and four USB port 1-4.Only for illustrating, the input/output end port of other specification also is feasible to above-mentioned USB port.This control module 10 can be usb hub integrated circuit (IC) or the USB controller under usb hub IC control, USB port 1-4 can be converted into the port of other specification, such as DVI port (Digital Visual Interface), printer port, the network port, telephony port, the audio port, the MODEM port, the PS/2 port, IEEE1394 port and RS-232 etc., to connect different external device (ED)s, such as printer, microphone, loudspeaker, display, hard disk, grid line, mouse and keyboard etc., this control module 10 is connected to USB port 1-4, and in order to be electrically connected the USB port 6 of USB port 1-4 and computer 2.
About the running between computer 2 and the port expander 2, when port expander 1 is connected to this computer 2 by USB port 6, this control module 10 namely establishes a connection with computer 2, and send hub information to this computer 2, this annexation includes the device explanation, for example manufacturer's title and the product data of this port expander, after port expander 1 is obtained necessary information, computer 2 can communicate with port expander 1, therefore, when external device (ED) (such as mouse) was plugged in one of them of USB port 1-4, computer 2 can be crossed this port expander 1 and connect this external device (ED).
