今天在mac上连接一个android设备发现连不上，adb devices看不到设备。于是想用lsusb命令看下，结果发现Mac居然没有这个命令，于是网上搜了下。发现了以下的命令system_profiler SPUSBDataType，但每次都输入这个命令我也记不住啊。于是自己在～／bin下创建个lsusb文件，输入system_profiler SPUSBDataType。 然后加上运行权限，这样Mac下就能用lsusb了。
然后使用lsusb查看到android设备的 vender id: 0x19d2 Product Id:0x2207
输入： vi ~/.android/adb_usb.ini 命令，在打开的 adb_usb.ini文件里加入Vendor ID相应的值， 然后保存退出
然后输入adb kill-server 和adb devices 命令，就应该能够看设备了。
mac os 的系统信息有相关内容。
命令能够显示system_profiler SPUSBDataType
$echo "system_profiler SPUSBDataType" ~/bin/lsusb
$ chmod +x ~/bin/lsusb
$ lsusb
