It gives you direct access to your memory card like it's a memory card on your computer.
Put in a micro SD(8GBhc in my case) card,
Plug in a micro usb cable (In my case I used a mini usb cable that fits Motorola Phones and Blackberry phones with the $5 adaptor I bought to be able to use all my mini USB chargers), go to 'settings and tools,8 is USB auto detection, select 'sync data'. back out go to 'tools' and highlight #9 'USB Mass storage'.
Plug the usb cable into the phone and computer and hit 'ok'. shortly you'll have another 'removable disk' under 'my computer'.

However, I did exactly what you said and after connecting my phone and selecting USB Mass Storage, is gives me the following error on my phone: "Connection Failed, Check Cable Connection" Although the phone is charging and making a connection without a problem.
