Mac下驅動BCM20702A0 USB藍牙

偶然高了一個USB藍牙，查到Mac下能識別，無法驅動，就去找了一下。方法很簡單，就是把藍牙的PID和VID加入到驅動里邊去，具體方法和步驟如下：
1. 進入到/System/Libary/Extensions目錄
2. 備份IOBluetoothFamily.kext
3. 在IOBluetoothFamily.kext右擊，選擇顯示包內容
4. 進入Contents/Plugins
5. 右擊BroadcomBluetoothHostControllerUSBTransport.kext，選擇顯示包內容
6. 進入Contents
7. 將Info.plist拖到桌面進行修改
8. 在下面的代碼中把PID和VID做對應的修改即可
