 Posted: Sat Feb 26, 2011 5:36 pm Post subject: A look at Win7 SP1 USB (56k!) |
 |
|
Windows 7 service pack 1 has a bug which does not updated the USB port drivers. The problem with the USB bug is it will only update drivers located in WinSxS and FileRepository not in the active location windows/system32.
USB drivers affected are "usbport.sys, usbechi.sys, and winusb.sys"
Users with this bug are those who did the following
-Install service pack 1 through Windows Update
-Install service pack 1 from the standalone copy downloaded from
Microsoft.
After reading that problem, I've decided to check it out by installing a few copies of Windows 7 through a virtual machine and here are the results.
Note: the only file being verified is usbport.sys as it's running in a virtual environment.
Img#1: A clean version of Windows 7 Professional no SP1 and all the USB driver version are exactly the same in the 3 locations: WinSxS, FileRepository, and System32
Img#2: Service Pack 1 is installed from the standalone copy downloaded from Microsoft. Notice usb driver from system32 isn't updated as the version is still "7600" instead of "7601"
Img#3: USB driver is still at version "7600" when installing service pack 1 from Windows Update
Now that both options have this bug, I've created a new Windows 7 with Service Pack 1 integrated into the package and give that a try.
Img#4: With service pack 1 integrated into the package, the USB drivers in all 3 locations are displaying their correct version.
How to fix?
According to the web, there are 2 options to this fix.
Option1: Go to device manager remove all USB ports and restart.
This will make Windows look for the updated USB drivers and users may have to reinstall any drivers associated with their USB devices.
Option2: Use the Pendmove tool and let that apply the correct files to system32
To run the tool, do the following
- Download pendmove
- Extract and copy the correct platform into your system32 folder. If your using 64bit use the 64bit version of pendmove
- Use pendmove and execute this code
| Code: | if ["%PROCESSOR_ARCHITECTURE%"] == ["x86"] goto x86-32
if ["%PROCESSOR_ARCHITECTURE%"] == ["AMD64"] goto x86-64
echo Invalid PROCESSOR_ARCHITECTURE!
goto end
:x86-32
set SourceRoot=%SystemRoot%\winsxs\x86_usbport.inf_31bf3856ad364e35_6.1.7601.17514_none_bfc9c95e61cfba61
set SourceRoot2=%SystemRoot%\winsxs\x86_winusb.inf_31bf3856ad364e35_6.1.7601.17514_none_f9fc4e7173e3735c
goto start
:x86-64
set SourceRoot=%SystemRoot%\winsxs\amd64_usbport.inf_31bf3856ad364e35_6.1.7601.17514_none_1be864e21a2d2b97
set SourceRoot2=%SystemRoot%\winsxs\amd64_winusb.inf_31bf3856ad364e35_6.1.7601.17514_none_561ae9f52c40e492
goto start
:start
pushd %SystemRoot%\System32\drivers
copy %SourceRoot%\usbehci.sys usbehci.sys.new
pendmove usbehci.sys.new usbehci.sys
copy %SourceRoot%\usbport.sys usbport.sys.new
pendmove usbport.sys.new usbport.sys
if exist winusb.sys (
copy %SourceRoot2%\winusb.sys winusb.sys.new
pendmove winusb.sys.new winusb.sys
)
popd
echo Now you need to reboot.
:end
pause |
Options 3, not discussed in the fix is to create a new copy of Windows 7 with service pack 1 integrated.

Most will just use the native drivers provided by Windows, unless the USB driver provided by AMD has some special features.
USB 3.0 are not native to Windows so you will need drivers for it.
