my ultrabooks touchpad moves the cursor and clicks, but two-finger scrolling is completely gone, in Settings, teh touchpad page lost most of its options too... this started after teh SteelSeries Engine update, in Device Manager I see this:

USB Audio Device Properties
Device status:
This device cannot start. (Code 10)
{Operation Failed}
The requested operation was unsuccessful.
I didnt realzie how much I use gestures until they vanished :/ now Im reaching for the scroll bar like its the early 2000s. is the Precision Touchpad driver gone, or did the vendor dirver replace it?
