Sorry. It was a self power hub. I've also left it plugged in to a root
hub but that was with earlier versions of u-boot.

Heh.. All we got was Mako's phone(s) and then the debug board you sent
later. So we don't have that device to trouble us.

Will do. Now that I know it _should_ work I'll start sniffing. Any
recommendations for connecting to the battery such that I can get
inline? I suppose I could tack on some small wires if I'm quick with
the iron. Do I have to hook up the one-wire signal as well?
Oh.. And thanks for the cc of the hardware list. Somehow I missed that
list. I just subscribed and I'm looking at the archives now.
