PS3 Compability With PS2

Just wondering if the ps3 controller works with the ps2?

i dont think so, i think the ps2 controller works on the ps3 tho,..

no, one uses the PS2 plug, and the other is either wireless or uses a USB connection.

O ok so the PS3 controller uses USB if it is the wired version?

yeah, usb 2.0 lol.

What if I use the USB port in my PS2?

maybe, you might get something, I doubt it though unless it's a game that needs a usb keyboard and is actually reading the USBs for a controller of some kind.
