  • If they are USB serial devices then they will most likely show up as ttyUSBx. You can also check the log with dmesg | grep tty – Dirk Dec 6 '18 at 12:59
  • @Dirk I check on dmesg | grep tty but it doesn't show the ttyUSB – ABC Dec 7 '18 at 2:24
  • @Dirk also when I try to ls -t /dev/*, the ttyUSB is missing – ABC Dec 7 '18 at 2:26
