Yer i think it's just a bit screwy control wise, I need to squeeze the knuckle and press the roller pad to activate, but it gives little control other than faster and faster, same for bringing the menu up, pull the trigger and kinda spam the B button and it sortta works sometimes.Make sure HS2 has the focus and it should work fine.
The roller pad interaction seems to be the issue, Im hoping there is a 3rd party fix/mod like that one in HS1 at some point.
