Failed connecting to port /dev/ttyACM0 status:Error

  Hello,

   

  You have to do so because this command will only affect the current session. Have a look at this discussion in Stack Overflow. 

   

  1. Identify your device by running:

     sudo dmesg | grep 'Intel F450' -A 5 | grep ttyACM

     The output should be something like: "... ttyACM#: USB ACM device ..." - where # is the port number.

  2. Grant the necessary permissions for your user, to be able to communicate with the device:

     sudo usermod -a -G dialout $USER

     Log out of your current session for this to take effect.

  Yu-Chern Peh Thank you for your answer,

  I ran the commands as you mentioned in your comment. (https://github.com/IntelRealSense/RealSenseID/tree/master/tools#linux----compilation-and-usage)
  However, when the error persisted, I saw on a different site.
  I tried the command "sudo chmod a+rw /dev/ttyACM0" but when the error occurs, I run the command "sudo dmesg | grep 'Intel F450' -A 5 | grep ttyACM" and multiple devices appear. It fixes itself after a while.
