Transferring files to a PSP
I connect my MacBook to the PSP via a supplied USB cable, and select USB connection on the PSP screen. When I do this, an icon for the PSP appears on the MacBook desktop. I can drag and drop files to this, and the MacBook copies the selected file (for instance, an mp3) to the PSP.
But, when I try to access the files from the PSP, I can't.
What am I doing wrong? Incidentally, is it possible to establish a wireless connection?
MacBook, Mac OS X (10.5.4)
