Looking for a usb 2.0 to 3.0 adapter?

Hey everyone, so I have a sony vaio vpceb33fx laptop. It doesn't have usb 3.0 as far as I know. However, I need one usb 3.0 slot to use a black magic intensity shuttle hd capture card. Is there any adapters or any way I can turn just 1 or all of my usb ports from 2.0 to 3.0? Thanks
