Microsoft resolves an issue in Windows 7 SP1 and Windows Server 2008 R2 SP1 involving binary files in some USB drivers which would no longer update. "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," Microsoft noted in KB2529073.
The company also offered additional details about the glitch:
- This issue does not occur when you install USB drivers by using a custom description device information (.inf) file that was provided by the computer's OEM.
- This issue does not occur if you are running a slipstream version of Windows 7 SP1 or of Windows Server 2008 R2 SP1.
According to Microsoft, at fault is an issue related to the way that USB driver files are labeled:
"This issue occurs because both the Usbport.inf file and the Usb.inf file refer to the Usbhub.sys file. Therefore, Windows cannot copy the driver files to the destination location during the driver installation process," the company explained.
