I am trying to use an Arduino Uno, but I am unable to access the serial port, I have followed the wiki guide in installing the arduino packages.
I have installed the arduino and arduino-avr-core packages from the standard repository.
I confirm that I am in the uucp group.
[~] groups raphaelc
lock tty uucp docker raphaelc
Am I missing a step? I have looked at posts from others with similar issues, but comments of those posts suggest that their workaround is outdated and the arch linux arduino package should work without changing ownership of
I looked at the ownership of the lock directory and find that the contents are owned by root
[~] ls -l /var/lock/

I would say that your fundamental problem is that there is no /dev/USBx or [/dev/ttyACMx in that last of devices.
Any chance you have updated your kernel and not rebooted? Check the output of uname -a and of pacman -Q linux and ensure the versions match.
If not, disconnect your device, connect your device, and post what is added to the journal when you did that.

I tried to look at any changes in my journal by using the command
journalctl --since "5 minutes ago" -f
I plugged and unplugged my arduino multiple times, but didn't see any activity get logged in the journal.
I have rebooted my computer multiple times.
pacman -Q and uname -a return the same linux image

Try a different cable. If the Arduino does not enumerate on the USB bus, there is no way it will show up as a device node. Since there is nothing in the journal, it is not even trying.

I tried a different cable without any luck.
I got some arduino output to show up on my journal, but that might be due to me messing around with the IDE rather than anything that's happening with the serial port.

Perhaps the problem is my power management settings? But I can't see why that would be because I can plug a keyboard and mouse just fine.
I can perhaps test if my arduino is actually working properly. It seems to power up just fine. I'll have to figure out a way to test it.

Do you have another Arduino? Can you test your Arduino on another system?

I tried it on my Windows partition and it didn't seem to work, so I'm guessing its my board. I ordered a new one and it might come in a week.

What kind of Arduino is it? Does it have a FTDI chip or second processor to do the serial to USB conversion (UNO, Mega, Nano)? or does it AtMega processor have integral USB (Leonardo)?
I have seen the Leonardo go stupid if a program is uploaded that does no serial I/O; you just cannot get the attention of the boot loader unless your are lucky. Once you get the second Arduino, you can rig it as a ISP (In Circuit Programmer) and reflash the dead Arduino through the Atmel ISP header. Or, you can get a dedicated IVR ICE or Kanda programmer too.

I am using the Arduino Uno. Thanks for the tip about reflashing it. I'll look into it!

Yup. It was definitely a damaged arduino. My new one works great.
