You can do two things: First, you can try to get a new usb cord to see if that works. Secondly,If there is a micro sd card slot on your phone, you can put a micro sd card into your phone. I think you can transfer all your files to it. After that, you need to buy a converter from a micro sd card to a regular sd card. If there is one on your computer, you can put the card into a built in slot on your computer. If you don't have one, you can just buy another converter from an sd card to a usb and plug it in.
