Axoloti not powering on

[Pr0fessorDeath]

Hello, fellow Axoloti Community.

I received my Axoloti yesterday and installed all the necessary drivers and software. I booted it up and played with all the demo patches and started learning how to make my own. That was last night. This morning I came in and everything was just as it was. I plugged in the USB cable and noticed that the red/green led lights did not come on. I tried powering the board with a different power source but it still not turning on.
I tried to figure out how to troubleshoot this on my own by looking through the manual and the help guides and doing a search through the forum. I'm pretty new so I may have missed it. I would appreciate anyone's assistance with troubleshooting this issue further.

Sincerely yours --

The first thing to try is doing rescue flash, this procedure is described in the section "Rescue mode (DFU)" here"

Use only for headphones (headphone jack is electrically biased at 1.65V.) 6.35mm (1/4") Stereo connector input and output, (labeled on the backside of the circuit board). 5 pole DIN connectors are MIDI in- and output (labeled on the backside of the circuit board). micro-sd-card (should be FAT formatted) micro-usb serves connection for Axoloti software, a power source, and act as a class compliant midi device. power input: 2.…

On Windows this needs an extra step to install a compatible usb driver, documented in the section "Advanced installation (Rescue mode)" here:

Installing on Windows

Normal Installation To reduce size we split the application into two parts, the main axoloti application, and a runtime which contains other required files. You must download and install both initially. (Usually updates will only require the main application to be downloaded and installed.) download both application bundle and axoloti_runtime go to http://github.com/axoloti/axoloti/releases, you will see the 'latest release' download axo_runtime_win.(version).msi download axoloti_win_(vers…

Thanks very much, that seems to have fixed my issue.

That's good news!
The common cause for symptom you've observed (no red/green leds flashing during powerup) is unplugging the board while firmware flashing is in progress.
I don't understand what would have caused this between last night and this morning, if this happens again without apparent cause, please give a shout.

I think that explains it. I think I had a bad usb hub which I've fixed. I was also screwing around with getting it running on an old netbook with windows xp and it wanted me to flash the rom when I plugged it in the first time? So I let it do it and I think that's when my usb hub shorted out the connection.
