Anyone used TM-1 via Overhub? Issues?

Anyone running TM-1 via overhub(i mean the TM-1 plugged into the Overhub)?
Does it power it nicely without an additional power adaptor or is that a necessity?

I have been using an iconnectivity mio xm for my midi for a little while, it does usb midi well but doesnt seem to do overbridge (its just not designed for streaming audio over usb…). A while ago I picked up a MD that came with a TM-1, trying it out today and it is rock solid, so my idea is to use the TM-1 for my OT and MD and the DN and A4 can do their thing via Overbridge.

(i dont have overhub yet… I guess this post is me trying to decide if I should get it)
