Like this, I presume?
The engineering seems really fascinating, I wish there was an image, like the one below that was a bigger & showed more detail. This tiny picture was the only one I could find.
To the best of my knowledge, none of the currently available Playstation to USB adapters supply enough voltage to drive the Dualshock motors. I know that my Kiky X-series adapters don't support Dualshock.
To the best of my knowledge, for an adapter to support Dualshock, it would need additional voltage. As I understand it, the 5v being supplied by the single USB cable only powers the adapter board, analog thumb switches and the digital buttons. From documentation & pictures I've seen floating around in cyberspace, it appears that the small motors need 3.3v & the large motors need 7.7v.
If I remember correctly, within the past few years, someone blogged about adding rumble support to a Kiky adapter by soldering on an extra USB cable to power the Dualshock motors. I never bookmarked that page & I can't find it again. I wonder how that would work. 3.3+7.7=11. If the motors need 11v and a second USB connection only provides an additional 5v, you're still 6v short. Where do those 6v come from?
