As the comments said, USB 3 drivers are not something that Windows supports natively.
Your main question came about the speed - there will be no difference unless your USB memory stick is USB 3 compatible.
This gets quite advanced, I am assuming you have a working knowledge of the command prompt. I would recommend you add the various Microsoft directories to your path, or run the
Windows PE Tools Command Prompt instead of the standard one. If I loose you at any point, please write in comments and I will be happy to help.
What I recommend you do is download the Microsoft Deployment Toolkit, and download your USB drivers.
Once downloaded, load the
Deployment Workbench and load the
Windows Automated Installation Kit.
Once this is downloaded, you can use the "copype" command to copy the required Windows PE files to a staging folder. Assuming you wanted
c:\win_pe_32 you would use:
copype.cmd x86 c:\win_pe_32
For 64 bit use:
copype.cmd x64 c:\win_pe_64
(I won't give two versions from now on, simply use common sense and replace 64 with 32!)
This will basically copy the required Windows PE files to the folder above.
Next, we need to mount the
boot.wim file (The part that actually loads Windows PE). Do this with the ImageX command:
imagex /mountrw c:\win_pe_32\winpe.wim 1 c:\win_pe_32\mount
This will mount the
Wim file to the
To load the driver, have the path to the
.inf file and run:
peimg /inf=<path> c:\win_pe_32\mount\Windows
If you explore this folder, you can add additional files if you wish. Personally, I include ImageX so it is available from Windows PE.
Now commit the changes by typing:
imagex /unmount c:\win_pe_32\mount /commit
Now you simply overwrite the default
boot.wim file with the
winpe.wim you just changed.
copy c:\win_pe_32 c:\win_pe_32\iso\sources\boot.wim
Lastly, we use the Microsoft Mastering tool with the following command:
oscdimg -n -bc:\win_pe_32\etfsboot.com c:\win_pe_32\iso c:\win_pe_32\winpe_32.iso
and congratulations! You now have a new bootable Windows PE
iso file with the drivers included.
You can burn this to disk, and hopefully, everything should work - as long as the driver is compatible with Windows PE!
