sudo chmod 777 /dev/ttyUSB0 就是串口没有权限，串口文件根据你自己的修改

I was struggling with the same issue with rp_lidar and in my case it was usb cable to the usb-uart converter. I checked something like 12 different usb cables and two of them worked fine. try: ls -l /dev | grep ttyUSB if there's no response then try another USB cable
