hmm... did you ever have any luck with endpoint 0x81, or has this  
been part of the problem all along? (Bear in mind that control  
messages go to endpoint 0.)

I just remembered, the USB Prober application (should be on your  
system as part of the OS X Dev Tools) has a tree that shows all sorts  
of lsusb-like information about devices.

Can you run that, choose "save output", and post the portion of that  
tree that corresponds to the device in question?
