[Galaxy S II Themes and Apps] fxrb:
For USB driver only installation I normally recommend the thread by SamHaLeKe. However the download link is offline again due to... that would be an endless story.

I know the USB drivers have been uploaded to other sites but I do not know how good and frequently these are maintained.

Anyway: I just decided to write this little list of instructions so everybody will be able to extract the USB drivers from the official Samsung Kies download himself as long as Samsung does not provide a download link (yes Samsung, even Intel provides “driver only downloads” :)). These are the steps to follow:

0. Make sure Kies is not installed. If it is you don't need this guide ;)

1. Download Kies from Samsung

2. Double click it to start the installation but do not go any further when you see the first dialog box looking like the first screenshot attached. Don't close the dialog box for now!

3. Use the file explorer to search for a file named “*kies*.msi” starting at or below this location: “C:\Documents and Settings\your_name\Local Settings”. I found a file named “Samsung Kies.msi” which is roughly 90 MB in size at some temporary directory. Your file may be named different or it might be located at some other place. I will call the file “Samsung Kies.msi” for the rest of this description.

4. Copy “Samsung Kies.msi” to some safe place, say “c:\kies-installer\Samsung Kies.msi”

5. Now press the cancel button in the dialog of step 2, not the next button.

6. Open a console in “c:\kies-installer” and type this: 'msiexec /a "Samsung Kies.msi" /qb TARGETDIR="c:\kies-installer\extracted"'. Don't worry, this will not really install Kies, it will perform an administrative installation which basically extracts and copies files from the installation package for later installation. You will also see a somewhat strange looking dialog similar to the one in the second attachment. This too is nothing to be worried about. The dialog will close itself.

7. The installer has copied the files to the newly created sub directory "c:\kies-installer\extracted". This directory contains a sub directory named “program files\Samsung\Kies\USB Driver” in which you will finally find a file named “SAMSUNG_USB_Driver_for_Mobile_Phones.exe”, the USB driver installation package.

8. Copy this file to a safe place and delete the entire “c:\kies-installer” directory. Again note: these files have not been 'installed' only copied to this location, so it is safe to just delete them.

9. That's it, the file “SAMSUNG_USB_Driver_for_Mobile_Phones.exe” is the USB driver installer we were looking for :D

I have tested the steps above on a Windows XP system for the following Kies (USB driver) versions:

2.2.0.12014 (USB driver version V1.4.103.0)

2.3.2.12054 (USB driver version V1.5.5.0)

2.3.2.12064 (USB driver version V1.5.6.0)

2.3.2.12074 (USB driver version V1.5.6.0, not changed)

2.3.2.12085 (USB driver version V1.5.9.0)

2.5.0.12094 (USB driver version V1.5.15.0)

2.5.0.12104 (USB driver version V1.5.16.0)

2.5.3.13043 (USB driver version V1.5.23.0)

2.6.1 (USB driver version V1.5.29.0)

For Windows 7 and other versions of Kies things might differ a little bit.
