Abstract

The invention discloses a computer peripheral device. The computer peripheral device comprises a USB (Universal Serial Bus) concentrator, built-in card readers and a controller, wherein each built-in card reader is in telecommunication connection with a built-in downstream end USB port of the USB concentrator, and the controller is in telecommunication connections with the USB concentrator and the built-in card readers and controls the same so as to monitor whether the built-in card-readers are needed to be kept in connection. When the controller judges that one of the built-in card readers is not needed to be kept in connection, the controller sets the built-in downstream end USB port corresponding to the built-in card reader to be in a first state, so that the built-in downstream end USB port can be considered as not being used. So that a computer host can be informed with that the built-in downstream end USB port is not used, then, the computer peripheral deice can enter into a sleep mode when other downstream end USB ports are not connected with any other USB devices, so as to save energy and electricity.

Description

technical field [0001] The invention relates to a computer peripheral device, in particular to a computer peripheral device which can reduce power consumption when a built-in card reader does not need to be connected. Background technique [0002] A USB (Universal Serial Bus, USB) port is generally called a universal serial bus port. Its main function is simply to simplify the wiring and connector types between the external peripheral device and the computer host, and the USB port can be connected by a The transmission line connects all kinds of peripheral devices in series to solve the number of cables and connectors used between the peripheral devices and the computer host, and it can also be plug-and-play, that is, various peripheral devices can be inserted at any time without restarting or installing. [0003] And when the number of USB ports supported by the chipset in the host computer is insufficient, a USB hub can be built in the host computer. In addition, in order...
