I appreciate the extra information.  In fact, I am having one heck of a
time trying to figure out exactly how to parse this.  I am reading with the
HID1_11 spec on my knee at all times, but I swear, I have never seen such a
poorly written document!  I am having a terrible time trying to figure out
the actual scope of each statement, which refers to what.  I don't run any
piece of Windows stuff here, so many of the pieces of demo software I have
found on the web do me no good.

I'm not giving up, I keep on making new discoveries, but if anyone knows of
a description of HID that involves some real use of English, I sure would
appreciate a pointer to it.
