Arduino does not show up in /dev/tty*

Hello Garuda users.
I am trying to flash firmware on my arduino nano 33 ble sense MCU and have connected it to my laptop running Garuda Linux (inxi below:)

Now ideally the arduino should have come up as /dev/ttyACM0 but in my case it is not. It worked for me in my ubuntu previously so I know hardware is not the issue.

dmesg output below shows that the system is indeed correctly even detecting the device.

I saw online solutions referring to usergroups and other permission issues but I doubt my case is even related to that. Output of lsusb says that a device is present as well:

Probably not related to the issue, but a reboot is pending.

Reboot solved it for me :slight_smile:

Worked for me, too. :+1:
