I think there may be some sort of homebrew app which will allow you to do this. Not 100% sure though. Of course you would have to have CFW and i dont know if you do. There are ways of connecting a keyboard and i think also a mouse to the psp for navigating the internet so i dont see why there cant be a way of connecting a pen drive to it. Even a Portable HDD hat wuld be even better. If there is a way and you find out then could you post it up here. I would quite like to be able to connect a pen drive up.
Hope ya find out a way
