The USB or S/PDIF input setting on the Schiit shouldn't affect the behavior of the USB interface, it just selects the DAC source. But I don't quite follow what you did different between your tests. Plugging in after boot works fine. Keeping the USB plugged in over a reboot works fine. Plugging in the USB while the laptop is off and then booting gives a missing alternate setting? Or did I get those last two mixed up?
