New user, cannot connect to TinyScreen+ 'No device found on ttyACM0'

[Lax]

Hello!

I recently purchased a TinyScreen+.  I am running Kubuntu 22.04 (LTS).  I am following the tutorial here:  https://learn.tinycircuits.com/Processors/TinyScreen%2B_Setup_Tutorial/ and am running into an issue.  When I try to upload the Blink or TinyScreen example I am always greeted with this error:

Code Select Expand

No device found on ttyACM0 
 
I am a member of the 'dialout' group and did run the following

Code Select Expand

sudo chmod a+rw /dev/ttyACM0.  I have correctly selected the correct Board and Port in the Arduino IDE but now I am stuck.

Running both

Code Select Expand

sudo chmod a+rw /dev/ttyACM0 &

Code Select Expand

lsusb I see the TinyScreen+ as connected.  But now I am unsure how to troubleshoot?

I'm brand brand new to this so I apologize if my questions are easily answered or newb-ish.

I figured this.  I needed to reboot or logout of linux and back in to allow it to see the 'dialout' group changes.

Just for future reference.!
