我可以编写一个打开/关闭 USB 的程序吗 [英] Can I write a program that swiches USB on/off

问题描述

我有一个 USB 调制解调器，它经常掉线.发生这种情况时，我拔下并从 USB 端口重新插入它，它会立即恢复信号；我可以编写一个程序来执行此操作，而不必物理断开调制解调器与端口的连接吗?

I have a USB modem and it often drops the signal. When this happens I pull unplug and re-plug it from the USB port and it gets the signal right back; Can I write a program that does that without having to physically disconnect the modem from the port?
