Dear all,

I have one issue when use one qualcomn's development board:

- test:
    definitions:
    - from: inline
      name: auto_test
      path: inline/auto_test.yaml
      repository:
        metadata:
          description: run
          format: Lava-Test
          name: run
        run:
          steps:
          - lava-test-case "Android_Serial_Case" --shell "./test.py"
    docker:
      image: myimage
      local: true
    timeout:
      minutes: 1600

The test.py is from our customer, when run it, it show the error:

Traceback (most recent call last):
  File "/usr/local/lib/python3.7/site-packages/serial/serialposix.py", line 265, in open
    self.fd = os.open(self.portstr, os.O_RDWR | os.O_NOCTTY | os.O_NONBLOCK)
FileNotFoundError: [Errno 2] No such file or directory: '/dev/ttyUSB0'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.7/site-packages/serial/serialutil.py", line 240, in __init__
    self.open()
  File "/usr/local/lib/python3.7/site-packages/serial/serialposix.py", line 268, in open
    raise SerialException(msg.errno, "could not open port {}: {}".format(self._port, msg))
serial.serialutil.SerialException: [Errno 2] could not open port /dev/ttyUSB0: [Errno 2] No such file or directory: '/dev/ttyUSB0'

I have linked the board to pc, and can see the "/dev/ttyUSB0" in my pc, what happened here?
