My psp is 3.40 OE, it registers fine on my ps3 (just cant use it because it needs to be updated) My brother is at 3.52 M33-4, and it had an error recognizing, i updated it to 3.72 M33 and the same thing. The USB like cant read, though when i try on a pc it reads it right away. Is it possible its the firmware causing this? Or What could be?
