1. Determine if the operating system recognizes the USB (ACM) device by entering a command:
cat /proc/devices |grep -i "ttyACM"
If the OS discovers a device driver, it responds with the device number followed by ttyACM, for example:
116 ttyACM
2. To query the system about USB buses and the devices connected to them, use the list USB command:
lsusb
If the OS discovers a USB device driver, it responds with the single serial port, using the USB parameter hex codes:
ID 210c:a4a7
This confirms that the appropriate USB (ACM) device is visible to the management computer.
3. Invoke Minicom to configure it.
minicom -s
