So I've got an application that allows me to download MP3 music. And I can connect/disconnect a USB to a Google TV (Logitech Revue). We have an SD Card as part of out Google TV. Can we connect/disconnect this SD Card like a USB? I've downloaded some music before to GTV; it went to the SD Card. I've just purchased a USB 16GB. How do I direct an MP3 download to the USB and not to the SD Card???
