no broadcast code was added to whitelist, swith to automatic connection mode

博主调试好GPS模块后，连接好硬件电路，直接运行livox开源的SDK时间戳同步程序后发现一个问题：

cdw@cdw-MS-7B89:~/Livox-SDK/build/sample_cc/lidar_utc_sync$ ./lidar_utc_sync 
Livox SDK version 2.2.0
Local broadcast code : 000000000000001
Invalid local broadcast code : 000000000000001
No broadcast code was added to whitelist, swith to automatic connection mode!
Livox-SDK init success!

Open /dev/ttyUSB0 serials fail!

可问题是我明明确认了端口号确实是/dev/ttyUSB0呀

cdw@cdw-MS-7B89:~$ ls -l /dev/ttyUSB*
crw-rw---- 1 root dialout 188, 0 12月  1 16:43 /dev/ttyUSB0
