Still it's perfectly vibrates on ps3 itself, using very same adapter... Well, guess just gonna live with that.maybe your usb adapter has no value for rumble, considering the ps2 controller isnt a pure hid controller an usb adpter must make the conversion so its ini file might not have rumble?
I know i own 2 ps3 controllers but both of them are six Axis so they dont rumble at all.
And btw, any plans on making native Nintendont on WiiU, running actually under iosu but not in vWii, just like wiiware, so wiiu gamepad finally reveals it's potential? I know this is a rough one, so I'm just curious if it's even possible.
