try to use usb-creator-kde usb-creator-kde
I had use it in kubuntu
now on neon LTS5.8.6 Qt 5.7.1 Kde 5.32.0 noyau 4.4.0-66-generic

Just after normal windows open,
another one comes with nothing explained, a one-line input field, in witch I can't write anything, and a botton names "annuler" (here, french speaking).
Nothing to do exept click that
After another windows "Voulez-vous vraiment quitter l'installation maintenant ?"
No -> back to the white windows
Yes -> close the program.

Log ....
