Software Deployment

Do you have "DriverSigningPolicy = Ignore" in the [unattended] section of unattend.txt and sysprep.inf?
Are the correct drivers installing (if you run the wizard when it appears, does it automatically install)?

If the driver is unsigned then it cant do the 2nd phase of the install to the driver cache, which is removing that New Hardware found wizard. do get rid of this you have to self sign the driver, deploy the signed driver and the certificates to the machine and that issue will go.

Look around for self-signing drivers.

Have you checked with the vendor to see if they have a signed driver available?

....or you could sign it yourself..... http://itninja.com/question/how-do-you-roll-out-new-machines?0873&mpage=1&key=
From AngelDs advice, I created a merge module which adds my generated certificate to the root of the machine before the action MsiProcessDrivers (when using DifXApp, that is). I'd sign the cat file with my private key etc before I compiled the MSI. It works like a charm. The merge module also removed the certificate on uninstall.
