One of the challenges with managing drivers in Configuration Manager is related to way drivers are imported into ConfigMgr. Duplicate drivers are ignored by default, so they don’t get put into the specified categories.
The System Center Configuration Manager team has made a hotfix available that changes the driver import behavior.
The hotfix is available here: http://support.microsoft.com/kb/2213600.
I’m not 100% sure if this will change from the way we handle drivers today, but I need to to back to my lab and figure that out…
