are there any playstation to usb adapters that handle the OG dualshock well? it seems like the hardest controller to implement, maybe those who wrote firmware for the chinesium ones didn't have a dualshock on hand to test, which is sad because it's a different set of SIO commands I think, and same goes for vibration on the dual analog controller
surprisingly the OG playstation controller tends to have no issues
also, the cheapo one DOES vibration if you put it into xbox 360 mode by double pressing the analog button on a dualshock 2
