Do PS3 Mad Catz Fight Stick Pro's work on PC?

I know earlier Mad Catz PS3 sticks wouldn't work on certain computers using certain chipsets, but what about the new PS3 Pro's?

Are they still just as iffy for PC as the earlier PS3 sticks? The 360 Pro's are backlogged on the MadCatz store until late August and I really don't want to wait that long for my stick especially with Ultra coming out around then. ;_;
