启用/禁用USB端口 [英] Enable/Disable USB port

问题描述

你好

除了USB电缆，我只想让LED闪烁.我已将电缆的一端切开，然后将每根电缆都连接到一块面包板上.由于LED不符合USB协议，因此我无法使用D +和D-线.所以我决定连接LED 到Vb并通过电阻连接到电缆的接地端.

I want to blink a led with nothing but a usb cable. I have cut the cable one the one edge and connected each one of them on a breadboard. Since the led does not comply with the usb protocol I can not use D+ an D- lines. So I decided to connect the led to Vb and through a resistor to gnd of the cable.

我创建了一个窗体，其中有两个按钮，每个按钮控制led的状态(当您按下button1时，led点亮，而当您按下另一个按钮时，led熄灭).是否可以启用/禁用特定的USB端口.

I created a form with two buttons each one controlling the state of the led (when you press button1 the led turn on and when you press the other button it turns off). Is there any to enable/disable a specific usb port.

 

预先感谢
