Boot Raspberry Pi / OpenPlotter 2 From USB SSD
After a few trials and errors and a couple of hours (well, a little more . . . ), I succeed to have my RPi4 booting from a 480 GB USB solid state drive (SSD) without the need of a SD card in the dedicated slot.

I am not familiar with Linux/Raspbian and so rely entirely on instructions found on Internet.

Basically, I started with an image of Openplotter  (Basic Moitessier Hat, I tried without success with the NOOBS) on a 16GB SD card, updated and upgraded the software (it did not work with the original kernel found on the image)  by  opening the terminal

# update your RPI
sudo apt update -y
sudo apt upgrade -y
sudo rpi-update

# reboot now
sudo reboot now

changed the EEPROM to the last beta version (2020-05-15)

# install the rpi-eeprom
sudo apt install rpi-eeprom

# Edit the rpi-eeprom and replace "critical" to "beta"
sudo nano /etc/default/rpi-eeprom-update

# Update/Install the beta eeprom
sudo rpi-eeprom-update -d -f /lib/firmware/raspberrypi/bootloader/beta/pieeprom-2020-05-15.bin

# reboot now
sudo reboot now

After the reboot, I connected my USB SSD and copied the SD card to the USB SSD with the RPi SD card copier software included in Openplotter. (Note I had no success with the sudo sync -avx . . . command in terminal nor with sudo cp ).

FYI, my SSD is a Kingston UV500 SUV500MS/480G memory card in a Renkforce – TED-U31SCRA1 enclosure.

So far, the only problem I encounter is the software for the Moitessier Hat that is not compatible with the latest version of the kernel.
