C:\Windows\System32\drivers\usbhub.sys is present.
C:\Windows\inf\usbhub.inf is not but C:\Windows\inf\usbhub\0000\usbperf.inf is present. (also …\0409\usbperf.inf.)
Did a lot of searching on internet an forums and nothing really addressed my issue.
System is totally up to date.
found something regarding update KB2529073, but it has already been applied to my system.
