This is not the perfect place for this question but it was the closest I could find

I have just bought a MED450X2 and want to transfer my library accross to the internal HDD, the manual says:
"Important, use the supplied blue USB3 cable for USB connection to your PC"
However, there is no such cable provided in the box !!
Is this a mistake in the manual or should I have actually received a USB3 cable ?
Many thanks,
GG.
