Hey I've been going round in circles, as in the title I am trying to get a raspberry pi 3b+ (which is rumoured to support usb boot) to boot from an SSD, it might work briefly but then nothing, I have successfully managed to get raspbian booting from the SSD. But this is ment to be a little media box for my children so a nice simple Kodi interface is needed.
Is there anyway to get this to work, booting from the SD card and then switching over to the SSD
