I have a PSP and am trying to connect it to my 10.8.4 Mini, without success. I set it to USB Mode, connect properly with cables...but the Memory Stick fails to mount. Can anyone troubleshoot this? Is it a Mountain Lion problem? -If I set the PSP to mount the UMD Drive instead, that mounts fine. -The Memory Stick mounted fine on my old computer running 10.4. -The Stick mounts fine now on my Windows 7 Bootcamp install. Appreciate any help.
