Mac下驱动BCM20702A0 USB蓝牙

偶然高了一个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

<key>PID 8684 0x21EC VID 2652 0xA5C</key>
        <dict>
            <key>CFBundleIdentifier</key>
            <string>com.apple.iokit.BroadcomBluetoothHostControllerUSBTransport</string>
            <key>Dongles</key>
            <dict>
                <key>GMYLE</key>
                <string>Micro Nano</string>
                <key>IOGear</key>
                <string>GBU-521</string>

                <string>4.0 LE</string>
                <key>Targus</key>
                <string>ACB10US 4.0</string>
                <key>UtechSmart</key>
                <string>4.0 (BCM20702)</string>
            </dict>
            <key>IOClass</key>
            <string>BroadcomBluetoothHostControllerUSBTransport</string>
            <key>IOProviderClass</key>
            <string>IOUSBHostDevice</string>
            <key>idProduct</key>
            <integer>8684</integer>
            <key>idVendor</key>
            <integer>2652</integer>
        </dict>
