Reply to Mod for a broken xone:3D

So I bought a xone 3D from a pawnshop earlier this week. I've been playing around with it, and I don't believe anything electronically is working. When I plug the USB in, none of the lights turn on or anything, and the driver software refuses to recognise the controller (I assume because the controller is recieving no bus power somewhere along the way).

However, the mixer works beautifully (the mixer lights are working), and it still seems like a steal at 500 bucks. Sounds are great, everything works fine.

I plan on testing the midi in and out with a midi interface later this week, but I read in the manual that the midi out just copies what is sent over USB, and if there's no power and nothing is getting sent then I doubt the midi out would be sending any data.

So I was wondering, if I tear this sucker apart and end up having the replace most of the controller guts, would it be possible at all to hook up the pots, sliders, LEDs and everything to say an arduino?

Bonus question: does it sound fixable at all (just from there being nothing sent over the USB cable at all)? This is all a little premature as I still haven't swapped the fuse out yet, but I did an overhaul on my guitar's electronics and I'm itching to have a try at something a little more sophisticated maybe.

Thanks folks, all the best.
