I'm new to linux so excuse my lack of terminology. I'm having issues with selecting a com port from arduino IDE. I followed the arduino website installation and tried to access ttyACM0 because that's what the tools>port originally had. I tried giving my user access to the port using the sudo usermod -a -G dialout and then restarted my computer. When I opened up the IDE the "port" selection was greyed out and I cannot select anything. Tried bouncing the cable around to different ports and same result. Did I somehow remove my users permissions for the com ports, and how might I fix this?
The /dev/ttyACM0 port does not show up in the /dev directory when the device is in File Transfer mode. Try unplugging/plugging the usb connector, without pushing the BOOT_SEL button.
