USB -> PS2 Adapter

I was wondering is it possible to get a converter that converts a usb connection to a ps2 one?

to use for Pc? That’s the one i use and it work perfectly.

Im actually looking for one that does the reverse of this, which allows you to use pc/ps3 based usb controllers on a ps2

Well Ive searched around but havent found any adapter that does this “out of the box” as it were. Ive tried stringing various other adapters/converters together but to no avail. Seems like I’ll be using my HFS3 solely on the ps3.
