    Hi all,

    I have the latest version of the OpenBuilds Control Software on RedHat 7.9 Linux.

    I am receiving the following error message.

    I would appreciate assistance with this error. I believe I do not have access/permission to use all the USB ports.

    PORT ERROR: Error: Permission denied, cannot open /dev/ttyACM0

    I am new to Linux and hence I am stumbling my way through getting it to run.

    Thank you.

    Your user a account is denied access to the serial port because it doesnt have permissions. Usually either needs user account added to the 'dialout' group or port chmod. Google "my linux distro name here" + how to allow user permission to serial port. As different distributions handle things differently

    Hi Peter,

    How are you?

    I just wanted to confirm that adding the user to the "dialout" group worked on my Linux distro (Redhat).

    Thank you for the great support and the excellent software!

    Much appreciated.
