I made some more tests. It's a race, 1 out of 10 tries succeeds and the
chance that it does is improoved by inserting the usb drive while being
in the bios.
The F31 grub files i exchanged do not seem to have something to do with it.
Could it be a timing issue of some kind?
the sooner i hit the boot from usb button, after the stick got inserted,
the higher is the propability to start.
Are you saying you insert the USB stick _after_ turning on the
machine? Otherwise I don't understand the correlation between the
insertion and pressing a boot from USB button.
