After you install Windows 7 Service Pack 1 (SP1) or Windows Server 2008 R2 Service Pack 1 (SP1), binary files in some USB drivers are not updated. For example, the Usbport.sys, Usbehci.sys, and Winusb.sys binary files are not updated.
This issue occurs because both the Usbport.inf file and the Usb.inf file refer to the Usbhub.sys file. However, Windows 7 SP1 and Windows Server 2008 R2 SP1 cannot handle this situation. Therefore, some USB related binaries are not copied correctly when you install SP1 for these operating systems.
