[citation][nom]jonwall[/nom]wouldnt a wired 360 controller work? i think all usb controllers work with the ps3[/citation]
Not at all. Besides the fact that I have tried, it matters how these controllers send the signals. Not all USB controllers send signals the same way, nor do they all have the same buttons.
The 360 controller have 2 analog stick, 2 analog triggers, a D-pad, and 8 buttons. The PS3 controller has 2 analog stick, 2 analog triggers, but other than start, select, R3 and L3, all other buttons are analog (6-bit digital). Even the D-pad is analog (ironically).
