I have the dual stick xarcade that has the adapter with the usb, and ps2 on one cable split at the end. To get the PS2 to work, do you have to have a ps2 keyboard plugged into the passthrough at the other end? I have tried two computer trying to use the ps2, and either recognized that a keyboard was there. The usb works fine. I am testing the ps2 on my main computer as my controller that Tim built is PS2.
