/dev/ttyUSB0 not found #29

Hi, I'm running python3 on raspberry pi3b+.

The example code cant find the /dev/ttyUSB0 file.

I did the pip3 install as per the instructions. Is there any pre-requisite installs? Lidar is new out of the box.

/dev/ttyUSB0 is just an example path common for UART2USB on desktop Linux. I am not familiar with RPi3, but try a different path. IIUC with a correct configuration it should be /dev/serial0.
