Can any Micro-USB cable be used with Swiss Micro calcs?

I believe these cables came with one of the rechargable external batteries - the ones that are marketed for keeping your cell phone alive.. These cables, while physically appearing like a normal micro USB cable will NOT work to upgrade the DM42.

That's my experience too: some cables are only suitable for charging...
