This is one of the main problems with USB mics - since they have a built-in audio interface that can't really be taken off of it, they can't be used like regular mics. So no, you're not gonna find a cable like that - and the data passing through an USB connection can be almost anything, so it's not gonna magically convert back into analog audio. The only way to connect this particular mic to an external mixer is by routing it through a DAW to an extra output on your audio interface and connecting that to the mixer.
