small mystery for teh driver experts:

USB Audio Device Properties
Device status:
This device cannot start. (Code 10)
{Operation Failed}
The requested operation was unsuccessful.
thats the last missing driver on my older desktop. SM Bus Controller with Code 28, everything seems to work fine, but Id rather not leave it like this in case its something like teh card reader or power management. im happy to share any details from Device Manager if it helps. I just dont know which information is the most useful for identifying the device. thx in advance!!
