Hi guys! I was programming my Arduino a few days ago and for some reason the usb serial port just seemed to dissapear. I didn't think I changed anything. I have tried multiple things such as reinstalling the arduino IDE, I downloaded new drivers. So it was there a few days ago and now it's just dissapeared. I don't know what to do because it's my main arduino programming computer.
Try unplugging & plugging the Arduino back in, then run
sudo dmesg
in the Terminal app. If you haven't done this before, then it will ask you for a password. You won't see any characters showing that you've typed it, but just hit enter when you're done. Then, copy & paste the output.
Same here.
What should this command do?
I got a wall of text in terminal, still no serial.
I unplugged my arduino nano and when I plug it back serial was gone.
Actually it is my second port that did this, my first one did the same a while ago... serial apeared on my second port only... now it is gone too.
This command will just report out what the OS sees with devices. If you could post the log that it outputted (tip: run sudo dmesg | pbcopy to copy it to your clipboard), that would help me see what's happening.
