OK.

Well, it's supposed to send data... it's just not supposed 
to be /coordinate/ data for the X Server.  It's supposed to 
be MIDI-related data for jog wheels and volume levels and 
whatnot.  It wasn't a problem in older versions of X11 
because it would be ignored (since it didn't have axes AND 
buttons).

So, looks like I need to change the kernel driver... to 
prevent it from appearing to the X Server as any sort of HID 
device.

Thanks for your help!
