Things You'll Need
Instructions
Attach the USB cable to the port on your PS3 and PSP.
Turn on both devices and select the "Remote Play Settings" option from under the Settings menu on the PS3.
Press the "X" button on the PS3 controller to "Register Device" and choose "OK" when prompted for a confirmation.
Scroll to the Settings menu on the PSP and select "USB Connection."
Select the "Remote Play" option from under the Network menu on the PSP.
Choose the "Connect via Private Network" option once prompted and then confirm the choice. The PSP will then display the message "Obtaining IP." As soon as it does, be sure not to press any of the buttons on the PSP.
Press the "PS" button in the center of your PS3 controller when the menu bar on the PS3 reappears. The red light will flash and then remain steady on the back of the controller. Once it does, you can use the PS3 controller to navigate the PSP.
