即：
Vendor ID: 0x2717
xxx@xxx ~ vi ~/AndroidStudioProjects/ ✘ xxx@xxx ~ vi ~/.android/adb_usb.ini xxx@xxx ~ cat ~/.android/adb_usb.ini 0x2717
再去：
adb kill-server adb start-server adb devices
结果：
xxx@xxx ~ adb kill-server xxx@xxx ~ adb start-server * daemon not running; starting now at tcp:5037 * daemon started successfully xxx@xxx ~ adb devices List of devices attached hmucaei75ptk7szs device
貌似可以找到设备了
如果这个办法有效，那就是：Mac系统的bug?
过了10多分钟后，还是可以检测到设备的：
说明的确有用，解决了adb检测安卓设备，红米Note8Pro，经常断开的问题。
那去调试看看，是否真的能连上？
[D 201209 10:40:52 __init__:287] device hmucaei75ptk7szs is online
可以连上的。
另外也去看看 android的adb_usb.ini
mac adb_usb.ini
android adb_usb.ini
【总结】
此处环境：
Mac电脑 + （Mac上TypeC转）USB的转接头（有3个USB 3.0的USB口 + 1个HDMI+1个TypeC） + 其中一个USB 3.0接口接 安卓手机 红米Note8Pro
现象：
Mac中用：
adb devices
开始能检测到 安卓设备 红米Note8Pro：
~ adb devices List of devices attached hmucaei75ptk7szs device
但是经常无故断开，而无法检测到
~ adb devices List of devices attached
原因：
估计是Mac的bug导致无故检测不到
解决办法：
Mac中把安卓设备的USB的vendor id=厂商id，加到 adb_usb.ini中。
具体步骤：
（1）先确认你的USB设备的vendor id
方式1：从 Mac-》关于本机-》系统报告-》硬件-》USB-》USB设备树-》点击你的USB设备->显示出：厂商ID
举例：
此处USB设备是安卓手机 红米Note8Pro Redmi Note 8 Pro
厂商ID=vendor ID：0x2717
推测：对应着 红米的厂商：小米？
其产品ID 0xff48 才是对应着 红米Note8Pro ？
方式2：命令行方式：
system_profiler SPUSBDataType
找到你的设备的部分，找到其中的Vendor ID
举例：
system_profiler SPUSBDataType 。。。 Redmi Note 8 Pro: Product ID: 0xff48 Vendor ID: 0x2717 Version: 4.04 Serial Number: hmucaei75ptk7szs Speed: Up to 480 Mb/sec Manufacturer: Xiaomi Location ID: 0x14230000 / 64 Current Available (mA): 500 Current Required (mA): 500 Extra Operating Current (mA): 0
其中：Vendor ID: 0x2717
（2）把vendor ID加到adb_usb.ini
- adb_usb.ini
- 位置：
- ~/.android/adb_usb.ini
- 举例，此处是：
- /Users/xxx/.android/adb_usb.ini
- 说明：
- 如果没有，则自己创建一个
- 把vendor ID加到里面
- 注意
- ini文件里面不能有多余空行
加了之后，可以用cat显示内容，确认一下内容正确：
# cat ~/.android/adb_usb.ini 0x2717
后续：
adb kill-server adb start-server adb devices
即可看到设备
xxx@xxx ~ adb kill-server xxx@xxx ~ adb start-server * daemon not running; starting now at tcp:5037 * daemon started successfully xxx@xxx ~ adb devices List of devices attached hmucaei75ptk7szs device
即可。
后记：
后续证明，只是当时解决了。没有彻底解决：
