At least sometimes, connecting the USB3 drive to the hub port formerly occupied by the USB2 drive results in a hands- off boot. Unfortunately, not always. Interrupting u-boot and issuing a usb reset command or two generally finds the USB3 drive, which can then be booted explicitly. I've captured one failure session at http://www.zefox.net/~fbsd/rpi2/bootproblems/bootlog-usb3-solo.fail but cannot reliably reproduce it. When the console offers the U-Boot> prompt, is that coming from bootcode.bin, or something else? Could anything be learned from trying to boot the armv7-configured disk on a Pi3B or B+ ? That's a relatively easy experiment. I'm trying to use a rather old Pi with a comparatively new USB drive. The Pi3s on hand are at least somewhat more modern. Thanks for reading, bob prohaska
