Req ManMac下驱动BCM20702A0 USB蓝牙 2017-10-22

偶然搞了一个USB蓝牙，查到Mac下能识别，无法驱动，就去找了一下。方法很简单，就是把蓝牙的PID和VID加入到驱动里边去，具体方法和步骤如下：

  1. 进入到/System/Libary/Extensions目录
  2. 备份IOBluetoothFamily.kext
  3. 在IOBluetoothFamily.kext右击，选择显示包内容
  4. 进入Contents/Plugins
  5. 右击BroadcomBluetoothHostControllerUSBTransport.kext，选择显示包内容
  6. 进入Contents
  7. 将Info.plist拖到桌面进行修改
  8. 在下面的代码中把PID和VID做对应的修改即可
