You are right, it seems like there is a third chip on the bottom side.
But it is very hard to get to it, and I don't think I could do this 
without risking to destroy something.

But I made some USB-Sniffs.
While doing this, I noticed the logfile grows to lots of megabytes in 
some seconds of idle state.
It seems like the host is continously sending the numbers from 0 to 255.
Is there some tool to edit usbsnoop logfiles? It would be difficult to 
delete the boring parts with sed/awk and I definitely can't distribute a 
50Mb logfile.
