How do I legitally transfer my PSP games to my PC?

[MMXZero2002]

I legitamitely own all my PSP games and I have an unmodded PSP system. I want to transfer my games to my PC (but still keep my original physical PSP games), but I don't know how to do it. I don't want any mods to be installed on my PSP and I want to transfer the games legitally. I know that the JCPSP emulator has a Decrytper checkbox under Configuration, but I don't know how to actually use this feature. I tried connecting my PSP to my PC via a USB cable, but my PC doesn't recognize the PSP at all. Any info on this would be greatly appreciated. Sorry if I spelled some stuff wrong, my spelling isn't the best any more.

Thanks.
