Great! Thanks for pointing out that file! (see my attached patch)

That was very useful information to know. So obviously it started off
by working, then somewhere along the init process it got confused and
locked itself up until a re-probing reset it. I dug into the file
Michael pointed out and have created a patch for this thing.
The HID_QUIRK_NOGET flag was required to make it work (so I'm guessing
whatever this "get" thing is that the flag is avoiding is what's been
locking it ... couldn't find any documentation about any of the flags
to know what was going on). With it set, this works right out of the
box; none of these ugly usbmodules workarounds needed!
The HID_QUIRK_MULTI_INPUT flag is required for it to register two js#
nodes so we don't need the ugly hack in libsdl.
Michael, Tim, and anyone else on this list wish a Dual Joypad, please
test this patch and tell us if it works on yours' as well (possibly
different revisions, though I expect we all have the same problem). I
would like to see this in the kernel :)
There is a 4-port version of this adapter, which has a similar hack in
libsdl for the multi-input. I expect that one could also use the
MULTI_INPUT quirk flag, and possibly the NOGET, as well. But I don't
have one to test nor do I even know the device ID.
Cheers,
