Be sure to copy-and-paste the name from the "ls" command that you ran
above as the name will be different for each printer.
### When the micro-controller restarts the device changes to /dev/ttyUSB1
Follow the directions in the
"[Where's my serial port?](#wheres-my-serial-port)" section to prevent
this from occurring.
### The "make flash" command doesn't work
The code attempts to flash the device using the most common method for
