Am I the only one that installed the update, but doesn't have USB output as an option? The icon is "greyed out" on the WIIM Ultra screen, and doesn't show up as listed in the app output selection screen. I tried connecting my laptop via USB (thought it might have been because a device wasn't connected) with the same result. Will it only output USB through a USB DAC or soundcard? In other words, it won't show up or work as a USB audio device when connected directly to a computer?
