在Mac OSX下检测连接的USB设备 [英] Detecting attached USB devices under Mac OSX

问题描述

首先要声明:关于Mac编程，我是一个新手.但是，我的作业需要与设备进行USB通信，所以我认为我将从一些基本知识入手.

First of all a statement: I'm a newbie when it comes to programming for the Mac. However I have an assignment which requires USB communication with a device so I thought I'll start with something basic.

我从此处中获取了代码，并从终端运行它.它启动并写:

I took the code from here, built it and ran it from the Terminal. It starts up and writes:

正在寻找与供应商ID = 1351和产品ID = 8193匹配的设备.

Looking for devices matching vendor ID=1351 and product ID=8193.

开始运行循环.

但是，在此之后，如果我插入和拔出USB设备(我尝试过:iPod，GPS，鼠标)，则屏幕上将不会写入任何内容，尽管据我所知，每次连接和断开设备时都应该写入.

However after this, if I plug in and out USB devices (I tried: iPod, GPS, mouse) nothing gets written on the screen, although as much as I understand there should be whenever I connect and disconnect a device.

我在做什么错了?

谢谢.

推荐答案

您也可以在终端上使用system_profiler SPUSBDataType

You can also use system_profiler SPUSBDataType on a terminal
