@jsa hmmm seems like just for audio discs.. but maybe it can do ISO's to USB as well
@codemonkeymike if I remember, there is an iso burning utility into k3 b, and if my memory is not more roten than I feel, you can modify the iso from the app before burning. K3b is a cd/dvd(/bd?) burning app, I fear you won't find an iso to block device writer in that app. For this topic, I've never saw more convenient than our friend dd.
@codemonkeymike I just use dd
@codemonkeymike kde's tool is called 'isoimagewriter'. Works well afaiac
Edit: looked up the link: https://apps.kde.org/isoimagewriter/
@codemonkeymike I discovered caligula this week and love it. It's a wrapper for dd that brings it into the 21st century.
