Abstract
The invention provides an externally connected controllable USB device. The device includes an HUB socket for a USB (Universal Serial Bus) hub terminal to plug, and an externally connected power supply is supplied via a DC converter and is arranged on a frame or is independently arranged. The communication state of the USB terminal on the device can be controlled by a computer or other control devices via a serial bus.
Description
Technical field：
The present invention relates to controllable USB device.According to the communication state of host computer command switch USB device upper terminal, and can keep it can data communication effectively.This equipment can be used for any application of existing USB device.
Background technology：
At present, USB device known to market is hot pulling and inserting type, that is, be inserted on USB terminal, and data just can be read and write with normal communication, i.e. the operation principle of so-called hot plug.Such as USB or USB HUB, do not exist insertion the order of magnitude number, all can normal communication.
As the shortcoming of the said equipment, this kind of common USB device, number of terminals is limited and reads and writes it is impossible to require arbitrarily to control with user to certain USB terminal concrete when using.
In sum, the USB device of existing market simply meets great mass of data reading and deposits, and its pluses and minuses homogeneously when substantially, can not flexibly control, and is unable to multi-layer connection use.The present invention will such advantage retain, solve between uncontrollable shortcoming and equipment again can not multi-layer connection shortcoming.
Content of the invention：
In order to overcome the shortcomings of that existing USB device can not control whether concrete USB port communicates, the present invention provides a kind of controllable USB device, and this controllable USB device can instruct according to user's host computer, controls this equipment specifically certain USB terminal whether normal communication.
