MCE_USB2 IR Transmitter - Here's a send protocol capture

Hi! I've recently bought one of these, mistakenly assuming that the 
transmitter would work - Of course, it's not finished yet. I saw a few 
messages stating that capture on Windows was not possible but I'm afraid 
I didn't quite believe that and tried anyway.

What works for me is a tetrahub - A hub with a transaction translator 
per-port. Not quite sure why, but capture with snoopypro from the device 
doesn't work with it directly attached to the port. Through a normal hub 
is broken as well. However, connected through the tetrahub, I see traffic.

Using 'hip' I can capture and send codes through the device.

Each transmission is sent in one request, with what looks like a blank 
ACK packet getting sent back. Here is part of the stream from a send of 
a RC6 (I believe - Sky UK remote) split up for easy reading:

(Up key - Send to blaster 2)

84897f7f7f
847f7f7f7f
847f7f7f7f
847f7f7f7f
815f80

As you can see, this looks generalizable to:

Start sending   x=6 All blasters     x=4 Blaster 1        x=2 Blaster 2
9f080x

Send code xx xx xx xx
84 xx xx xx xx

Finish sending ?
81 5f 80

Unfortunately, I'm having difficulty finding a good example to copy from 
for a USB blaster device. I'm only a copy / paste programmer, I'm afraid :(

Can anyone give me some clues?

Cheers,

Allan.
