Looking at this, I'm more tempted to remove the test for bType in the IRQ
-- this isn't the first device I've seen broken like this.  It's using a
UFI-style CBI interrupt for a non-UFI device.  This is, apparently, one of
many spec violations that windows silently ignores.

Stephen, what happens if you just remove the check (search the code for the
line that shows "CBI IRQ data showed reserved bType")?
