I've been rocking Android devices for quite a while but I don't understand something very basic. What is USB storage? My Note says I have 8.85GB of 10.84GB available? How can I use that space? Is it only utilized when I have the phone connected to my PC?
Keep in mind that you will not have access to the entire memory available on the device. Some is reserved for other purposes. But that's why you have an expandable memory slot for additional storage if you need it.
