Uniti Star: change USB from 'server' to 'usb'

I’ve been using an external drive via USB with a library of music and it’s shown up in the menu under ‘USB’. Since then, I’ve ripped a couple of CDs onto the external drive and decided against doing it since it takes so long. Naim has since renamed it and it no longer shows up under ‘USB’.

How do I make it findable under ‘USB’ again?
