One way to inject certain drivers is to do it post image deploy. On a few machines we have we've seen the USB 3.0 drivers are not injecting correctly or not at all with Windows 7. This is during Sysprep or during DeployAnywhere. The solution I have isn't elegant, but it does work every time on the problem machines we encounter with Windows 7 and USB 3 drivers:
@Echo off
REM Copy Drivers to production for Win7 x64
Echo Retrieving Model Name...
FOR /F "tokens=2 delims==" %%G IN ('WMIC baseboard get product /format:VALUE') DO SET Model=%%G
ECHO Model: %Model%
if "%Model%"=="OptiPlex 9020" goto 9020
if "%Model%"=="OptiPlex 9010" goto 9010
if "%Model%"=="051FJ8" goto 9010
if "%Model%"=="20B6005JUS" goto T440
if "%Model%"=="20BV000AUS" goto T440
if "%Model%"=="2344BPU" goto T430
if "%Model%"=="23426QU" goto T430
if "%Model%"=="234238U" goto T430
if "%Model%"=="2344C4U" goto T430
Goto END
:9020
xcopy "\\server_share_here\d$\drivers\Desktop\9020\HCSwitch\x64\*.*" "C:\drivers\9020USB\HCSwitch" /S /Y /I
xcopy "\\server_share_here\d$\drivers\Desktop\9020\Win7\x64\*.*" "C:\drivers\9020USB\Win7" /S /Y /I
pnputil -a C:\drivers\9020USB\Win7\*.inf
pnputil -a C:\drivers\9020USB\HCSwitch\*.inf
:END
And so on...
I've only put the 9020 destination even though the script example is calling for more model numbers that it may encounter.
