Greg:
My earlier experiment (adding a clear-halt for the interrupt-in endpoint)
failed. It turns out that it does cause problems for other devices. And
it wasn't needed anyway; a simple blacklist entry was enough to get my HP
keyboard working.
This patch (as643) removes the clear-halt call and adds the blacklist
entry.
