Emulate USB Flash Drive to install PES Option file

Hi,

Can anyone tell me how to get RPCS3 to recognise there's a 'USB' in the PS3?

This is how to import kits and option file to PES 2013. I put everything in the usb000/PS3/SAVEDATA but it doesn't recognise anything.

Where do I put all my files so that USB storage comes up?

Thanks
