Thanks for suggestion. Have to try that as well. Using unpowered hub 2.0 hub now.

Another workaround would be to make it a powered hub. Unfortunately some of those wireless keyboard/mouse dongles draw quite a bit of current from the USB and cause all kind of weird issues

Thanks to a tip from another ham, seem to have solved my problem with the RPi 4B locking up if using flrig with flidigi on my system.
Solution was to change to a wired keyboard and mouse. Probably saving a lot of overhead processing to keep the system going.
So if having similar issues, consider giving this a try. Also have a USB 2.0 hub plugged into my RPi to have enough ports with a couple of spares.
