Default what is the mini USB spec required to charge BB

Please Login to Remove!

I have wired a single mini-USB onto my motorcycle to provide power to any one of several devices including a garmin, my mp3 player, and I'd like to use it to charge my old BB. currently i have only connected the power and ground wires to the mini-USB cord.

i read someplace that BBs will not stay in charging mode if there is no "signal" on the other two data wires. i have found that to be true and unfortunately, i cannot find that post.

i'd like to build a circuit to supply the needed voltage to the data wires such that my BB will charge. does anybody know what is required?
