I recently bought a PSP and had it flashed to CFW 3.71 M33. I wanted to try out some homebrew so I bought a 2 gig Lexar memory stick. I inserted it into my memory stick slot, connected my psp to my pc's usb port via a usb cable, manually made the /psp/game/etc/ directories then transferd over a homebrew application which functioned properly. All was well until I proceeded to format the memory stick from the PSP's system menu for the benefit of having all the proper directories created. Now I am unable to transfer data to the stick. I can only create directories, whenever I try to transfer any sort of file all I get is a 0kb file with the original files name. It seems that when the stick was formated as it came from the factory I was able to transfer data to it, but now after a PSP system format I am unable to. As I said, I am using Linux and any information is greatly appreciated.
