Support direct-attached storage volume

[tensiondriven]

Great project! From the looks of it, the USB connection is only providing power to the Pi. I’ve been looking hard for a way to expose a storage volume directly to a host over USB, such that the host would see the connected device as a standard volume, and could read/write files to it.

In your hackster post you mentioned that the data pins are connected for this. Does SUBzero support this yet? As far as I can tell, there is no other solution available to do this right now.

If you can point me to the libraries needed to expose storage to the host overt USB (probably as a block-level device?) such that it appears as a standard direct-attached volume, I’d love to help make this a reality.

Or, any other background, notes, or other projects which already do this would be very helpful.
