I've got an early Pi2B (not plus) that has been booting reliably from a USB2 disk connected via a USB3 hub using just bootcode.bin and timeout on the DOS partition of the microSD card. A recently-configured USB3 disk was set up using FreeBSD-13.0-RELEASE-arm-armv7-GENERICSD.img but if it's plugged into the hub the Pi2 won't do anything at all on powerup. It's as if the Pi3 disk somehow locks up the Pi2 very early, before any output is presented on the serial console. If the USB3 disk is connected after boot is complete the disk seems to work normally, so I don't think anything is wrong with the disk. The same USB3 disk is in use on a pair of Pi4s without difficulty. I've updated the bootcode.bin file on the DOS partition of the microSSD card to the present version offered at https://www.raspberrypi.com/documentation/computers/raspberry-pi.html#special-bootcode-bin-only-boot-mode but that made no difference. This probably isn't a FreeBSD issue at all, but if anybody has seen this or can offer suggestions on what to try it'd be much appreciated. Thanks for reading, bob prohaska
