Install and test

These operations run in the Lemuntu system
Step 1: Insert the USB to Serial adapter into LeMaker Guitar.
Step 2: Check up wether recognize the usb serial port or not through the following command.

ls /dev/ttyUSB*

When find ttyUSB0 nodes,we can explain that it has correctly identified the usb serial port module.
Step 3: Run the command below to set up USB to Serial.
