That's the original USB-specs, you are referring to.
Mini/micro-A-plugs are using pin4-to-ground by these USB-spec, for electronically differenciating these.
What I wanted to pinpoint, is that HTC decided to mark pin4-to-ground for detection of their charging equipment.
And since micro-A plugs fit into micro-B sockets, you should be able to use a "USB A male to micro USB A male cable" for your charging needs (without modifying your micro-B cable, which can be quite tricky because of its size)
edit: I was wrong with that, it's the other way round, sry. Does the HD2 have a AB-socket then? I believe it's a regular B-socket.
Then if I stand correctly, you will still need a special modified micro-B-cable for charging.
To make it even more difficult, HTC-design does not charge the Kaiser with a regular mini-b-cable on a car-charger, because there was no data-signal on it.
My intention of this thread was asking, if this behavior has changed when going from mini to micro-usb design, and is still an unanswered question.
