Unplug your iMix, open up your device manager and expand the audio tab, then plug it back in. If USB Audio Device pops up, right click/uninstall it, then plug the iMix back in and hopefully it will reinstall correctly.
If it doesn't show up as a USB Audio Device, then look in the USB Controllers tab at the bottom and do the same thing.
Hope this helps!
