I've already tried to do a powercfg -REQUESTSOVERRIDE DRIVER "USB Audio Device (REALLY LONG 50 character string)" SYSTEM. it gives no message, error or otherwise.
When I type in powercfg -requests, the HS70 driver still appears with the kernel caller...
ugh, this is maddening. Cortana is off and USB selective setting is enabled per other posts I've found online.
Please help.
