As a comparison to the recent emerge of the Creative Micro Photo, here is 
the device descriptor for Creative Zen Portable Media Center, which is 
quite similar: the first endpoint (1) is merged with the second (someone 
realized you can use EP 2 in both directions, duh) otherwise it is very 
much the same.

As you can see, this one also lacks any descriptive strings.
