Considerations for connecting 5 pin wire cables and interfaces to USB?
It's not exactly clear, what you are saying. What I got is:
 1. you have a USB device, that provides only wire leads
 2. you want to connect to external USB port of the computer

You can cut an existing USB cable and solder or wrap wires together. Normally there would be some sort of filtering on any USB peripheral, so I guess you can try without anything fancier than that. Typical USB color coding you can see here
