ok so long story short: my ultrabook drains the battery in a bag after the WinFlash update.

USB Audio Device Properties
Device status:
This device cannot start. (Code 10)
{Operation Failed}
The requested operation was unsuccessful.
The battery is suffering, and so am i... i tried disabling hibernation and re-enabling it, but that changed nothing. What tools can tell me which device or driver is causing teh problem?? Happy to post reports here if someone can help me read them. Id especially like to know whether i should go back to the older chipset package or try the one from my PC maker instead.
