USB Boot on Raspberry Pi 4

For what it’s worth, @Jpsy his SSD boots with EEPROM firmware 2020-09-03, mine doesn’t.
Mine boots with v2020.07.16-138a1. For me it was worth the try.

I haven’t investigated the difference between, the versions (yet), but am happy with the fact that I have a (working) solution for the problems that made me wanna move to the SSD.
