+!!! tip
+    If your serial port is listed on linux ('ttyUSB0 CP2102' or similar) but you are unable to open it, make sure you give yourself permission to use that device.
+    Find the owner with:
+    `ls -la /dev/ttyUSB0` (replace ttyUSB0 with your device). If it says `root`, Chrome will not be able to open it.
+    Make yourself the owner by running `whoami` to get your username, and then to change the owner:
+    `sudo chown {your username} /dev/ttyUSB0`(replace ttyUSB0 with your device).
