问题描述

例如，在一个USB集线器中连接四个相同的USB设备，当测试一个是错误时，如何将其与其他USB设备区别开?

For example,four same usb devices connecting in a usb hub, when testing one is error, how to distingush it from the others?

推荐答案

每个USB端口有一个唯一的地址.通常，内部USB控制器也连接到集线器，将其拆分为多个端口. hub0和1的地址示例:
hub0:001A0000、001A0001，...
hub1:001B0000，001B0001，...
等...

祝你好运！

Each USB port has a unique Address. Normally the internal USB controller is also hooked up to a hub, splitting it to multiple ports. Address examples for hub0 and 1:
hub0: 001A0000, 001A0001, ...
hub1: 001B0000, 001B0001, ...
etc...

Good luck!
