As I understand it that's not possible with Pi before Pi 2 version 1.2
or something like that.  Basically Pi 3 and onwards can simply boot
from USB, earlier ones can't.
 

Yes, that is my understanding also. I think there was a time when you had to boot from SD and run a comm,and to change a flag in the firmware to allow USB only boot.
I have a Pi 4B and its supremely ecstatic booting from USB. And it's a totally simple setup
