confirmed that the boot loop behaviour went away for me with the addition of a battery.

Ok thanks Kite , I hope the OPs issue has the same easy to fix root cause.

Mine does the same - using the most recent (correct) image, I had assumed its because I haven't got a battery plugged in (and therefore the usb wasn't able to fully power the device causing it to restart). Waiting on a battery to arrive to prove my theory.

Something else to consider when using a number of devices on your hub..

I found that I had to power my hub from the 5v breakout board I made , and not just power the hub from the pi. Perhaps one or more of your usb devices are drawing too much current

I don't want to do preorders for this batch sorry. Just keep an eye on the thread by subscribing to it. Hi, can you already say when the boards including sound will be available? A rough estimate perhaps? ;) Are there plans to include the teensy or USB-Hub or so? Then I'd gladly wait for those ;-) ...

nope, nothing.
going to abandon usb audio and do pwm

Let me know if you get audio out of the emulators. I can get audio from emulationstation Ui, but not from any emulators

what voltage you feeding it?

also, try a different USB cable.. the first one I tried wouldnt work
