Fixed bug #4
[Note: I'm applying this patch since it's a cleaner version of what's already implemented, and supports this controller on older kernels. I'll ask to make sure this doesn't break on the new kernels where it's no longer necessary]

Subject: SDL Patch
Hey, Ryan.
I submitted the following patch about a year ago. It's just a simple
patch for the linux port, to make multiple joysticks each appear to SDL
as their own device, if they are on the same USB port (specifically,
these guys
<http://www.consoleplus.co.uk/product_info.php?pName=super-joybox-5-quad-joypad-converter>,
which allow 4 Playstation2 controllers to be accessed via a single USB
port). Without this patch, SDL pretty much drops the ball, and reports
that there are 4 joysticks available when less than that number are
plugged in.
My work built upon the work of another person with the same device. When
I submitted the patch to the list, he tested it, but it didn't work for
him, so the patch was never accepted. Maybe about 3 times in the past
year, I've tried to email the guy, to see if he couldn't run my new
version, complete with debug code to diagnose the problem he was having.
He never got back to me.
So, I'm attaching the patch. I wish I knew why it didn't work for him,
but I've been using it for the last year with no problems. Let me know
if you need any more information, or have any ideas as to how I could
test it. I'd like to see it in the tree, but I want to make sure it works.
-Chris
