Port list is empty on RedHat 8 #342

Getting an empty list from SerialPort.getCommPorts() on RedHat 8 on an x86_64 system. I am running as "root", but did those permission commands for root anyway. I am able to open named port and use it. Any suggestions?

What type of serial ports are you expecting to see? You say you can successfully open the port and use it...what is the port path you are using to do so ("/dev/...??")? What type of device is this that you are connecting to?

Also, please test the attached library version and see if it works any better for you. There have been a ton of recent changes that have not made it into an actual release yet. Thanks!
