What you need to do is simple, first if its a psp, make sure its in USB MODE by going to system settings>usb connection.

When you go to my computer, you will most likely see (if its a psp thats connected) "E Removable disk". Ok, Right now i want you connect your camara, or psp to your computer, and go to My Computer,, and tell me what you see.

Edit: Also try using a different USB cord.
