When the PSP is in USB mode, it means it is connected to a PC, and the PC can now transfer files onto the PSP's memory card.
Put usb cable into the top of your psp, and connect the other end to a usb slot on your PC. Then go into settings on your psp and click on usb mode. A window will appear on your PC giving you the option to view the files on your psp. If not go into my computer and find it there.
