Nope, but if you have a PSP fat and a slimline PS2 you're in luck because of IR remote which allows you to use your PSP as a wireless controller.
No it does not work for PS2
Unfortunately, you cannot.
Use you usb connector for you psp to connect it to your ps2 in the usb slot You have to be playing a game like Crash Tag Team Racing And Jak X (only ones i know) Then go to connect you psp and it might take a while for it to recognize it then that is it
You stick the short headed USB end into top of PSP and bigger end in to front of PS2 (If it's the old one) but if it's the new PS2 Slim put it into the back of it
Yes you can use a PS2 controller into a PC by buying a PS2 to USB connector. This is a connector that tricks the controller into thinking its a PS2.
It must actually be a PS2 controller for it to work
Of course you could, the jack on both Sony PS1 and Sony PS2 are exactly the same, although it lowers the performance than if you were playing with a Sony PS2 controller which means that you can not actually use the controller because who wants a controller that does not work completely. Used PS2 controllers are cheap and there are no good reasons to try and use a PS1 controller on your PS2 because it will not preform like a PS2 controller
I think it is the PS3 that the PSP works well with together and not the PS2
Of course not. A PS2 is a PS2, not a PSP.
No
Your controller is probably broken, it should work. Make sure it's a PS2 controller with a PS2 console.
Yes, there is an adapter that lets you use the controller for the PS2 with a PS3, it cost around $6.99.
