Currently it's running off an... um... powerbrick? Not sure what these are called, definitely not a phone charger.

Here's some new information, I remembered I have an old rPi lying around (from the original series, so not a 2) and I gave it a try and it's the exact same thing, i get video from SD card and no video from USB drive. But seems to boot otherwise, can blindly do the poweroff and it will react. This must either be a configuration problem or a hardware problem with the SSD or the USB dongle thing I have it in. The dongle and SSD seem to work if i connect them to my computer, sadly I don't have any other SSDs/dongles lying around to test if they make a difference. But I sorta lean towards this being a configuration problem, maybe I'm not setting something I should. Or setting something I shouldn't.
atomant:
I tried writing a system onto a pendrive and boot from that with and without the USB hub, again, same result. I'm puzzled...it must be some-sort of configuration issue.
Isn't there anything I need to change in config.txt or cmdline.txt to boot from an USB drive?

( if more amps/PSU/ ect fails to resolve issues )

I'll try this later.

... ::)
(AFAIK) if you want "official" support using their os+config is the only easiest way to get it
perhaps your hw setup + config it to esoteric
to have got'en much testing

Hi atomant
It's a bit of a long shot, but if you have a keyboard plugged
in while booting from your USB device, does that change
anything?
