Obtain drivers from MS-Server and updates from WSUS

Question

Hi,
is there a possibility to obtain drivers from the MS Server and the "other" updates from the WSUS-Server?
We have workstations with Win7 and XP and pluged in devices (USB) should obtain the drivers (if available) automatically from MS-Server.
Obtaining drivers through WSUS is not an option.
The Group Policy "Computer Configuration\...\Windows Update" is set to obtain updates from "intranet Microsoft update service location".
Should there be no possibility to distinguish between driver and update obtaining locations,
then is it possible to set WSUS as primary obtaining location and as secondary the MS-Serve? 
Greets, 
Emmanuel

Answer 1

Like I mentioned before I tried to use this:

1. Try:
Step1:
I uninstalled the device and deleted the driver of my testing device. (local)
Step2:
I have created a new GP on Server 2003R2x86 (AD/DC) and linked it in the OU where my test-PC is located.
.../ComputerConfiguration/Administrative Templates/System/InternetCommunicationManagement/Internet Communication Settings/TurnOffWindowsUpdateDeviceDriverSearching-->disabled
Step3:
I restarted the test PC with a logonscript: "gpupdate /force"
Result:
It didn't work.
2.Try:
Same procedure, but instead of creating the policy on the '03 Server, I created the policy with RSAT for W7.
Result:
It didn't work.
Now I have a new question:
Isn't the above mentioned policy for this?:
http://windows.microsoft.com/en-us/windows7/automatically-get-recommended-drivers-and-updates-for-your-hardware
I ask, because this is exactly the setting that has to be changed so that everything works the way I want.
(at least for the Win7 PCs. I don't care much about the XP-PCs because they will be replaced in the near future)
Well one option is to change this setting manually on every PC, but this would be a huge PITA.
Can this be done in a policy or with a script (registry?)?
