Salaam Mehdi,

Was that your way of telling me that I was putting the double 'A' on the wrong side of the 'L'? My apologies. Look at it on the bright side. At least I'm sticking to English transliteration. I would get it even worse if I tried to spell it with actual Arabic letters. And that would be even worse yet since I'm guessing that you speak Farsi and I wouldn't even know where to begin. Oy! ;-)

I'm looking into your enumeration issue right now. I'll get back once I find something to add. I can tell you that I have one of Jan Axelson's books, "The Microcontrooler Idea Book," and from what little I've looked at in it, he seems to be a good author.

In the meantime, I have a question. Is ACKNOWLEDGE_SETUP a function or subroutine or something? I suspect that this may be the source of confusion. ACK is an actual USB packet type (PID 0010) from the Handshake category. In any case, if ACKNOWLDGE_SETUP is a subroutine or something, post that code.

Now if you'll excuse me, I need to divert some of my attention to firewatch. One of those wildfires was just a couple of miles from my land when we left for church this morning.
