The RPI3B+ will boot into USB (without SD card), or at least it will using the same SD card plugged into a Dynex DX-CR112 memory card reader. That gets you past the rainbow screen and into U-Boot land. U-Boot (?) seems to be choking at that point. It goes through the partitions (setting currdev to disk0p#), but it is printing efipart_readwrite messages (rw=1, blk=2591 size=272 status=7). Varies by partition, but rw=1 and status=7 for them and long delays. Putting the same SD card into the SD slot and it boots up fine. As far as booting... https://www.raspberrypi.org/documentation/hardware/raspberrypi/bootmodes/host.md I want to say that is a fairly recent change, ~April 2018. Hmm. My Samsung disk is USB3.
