I've been using a Rockfire USB adapter with a set of Thrustmaster Elite  pedals alongside a Warthog for ages.  The Elites are still going  strong.  I bought them new with a Cougar sometime in the early 2000s or  so.  They've outlasted the Cougar, which I'm attempting to revive, and  may outlast the Warthog.  The pin cable from the pedals plugs into the  adapter, and the adapter plugs into a USB port.
