There are definitely some charge only non-data cables out there. The cables that came with my Panasonic 3D glasses do not work for data connections. The same applies to a couple of other micro USB cables that I have.

This caused me several wasted hour and much pain when I was trying to setup my Logitech remote.

I believe the same at one point applied to Apple 30 pin cables ?
