Help! I dont have a USB 2.0 cable on my power supply and case!

Solution
According to the specifications that case doesn't have any USB 2.0 sockets, just a couple of USB 3.0 ones. Do you need more USB sockets than those two plus the ones on the I/O panel of the motherboard? (You can use USB 2.0 devices in USB 3.0 sockets if necessary.)
The headers are on the motherboard. Do you mean that your case has no USB sockets or that it has sockets but no cable to connect them to the motherboard? What case and motherboard do you have? A picture of exactly what you mean might help.
 
Sorry i got confused a bit i dont have the USB 2.0 cable that has to connect to the header on my mobo ,I only have the USB 3.0 cable connected to my case. I have a Corsair Spec-03 and an MSI Z97 Mobo.
