yeah, it doesn' work anymore... it only worked in Orbiter 2006... in 2010 it does nothing
not too big a problem really - that thing was just a quick kludge i hooked up so i could try out controlling the RCS with my x52's throttle hat... these days i'm making good progress with it's much more ellaborate successor, a full-fledged DirectInput-based Multi-Joystick suite (check out the addons forum for latest version)
it does however, still bear a handful of limitations, such as, hard-overriding POV controls which trample over some kinda stock features, and it doesn't support buttons yet, which kinda makes it unfit as a replacement for OverrideRCS at the moment...
but plans are, it will shortly... and by "shortly" i mean, i gotta finish rearranging my PC desk at home first

(can't really work if i 'm not seated properly, right?)
but to answer your question... no, it doesn't work in 2010... the good news, you're not insane:thumbup:
if you can stick in with switching LIN/ROT a couple more days, i'll have a new version featuring the OverrideRCS functionality up in a bit:tiphat:
