T330 Windows Server 2008 R2 SP1 Install USB 3.0 Incompatibility

The T330 has no native USB 2.0 support.  Windows Server 2008 R2 SP1 installation media  has no native USB 3.0 support. So on OS installation the mouse and keyboard will not work.   I tried injecting the USB 3.0 drivers into the Windows 2008 server ISO (see: https://www.dell.com/support/article/us/en/04/SLN300618/en ).   Injection into the ISO works fine and it solves the problem of no keyboard or mouse in starting the OS installation

BUT once the base OS is installed and you come to the first post install  screen (when it is now booting from the hard drive ) to change password and continue setup, the keyboard and mouse are again in-operable.    My best guess is that the USB 3.0 drivers did not get installed to the hard drive.  I tried starting over and reinstalling the OS but same result.  The ISO creation per above KB post was clean and successful.  No errors.

I saw another Dell 'Faq' recommending disabling the USB 3.0 is system BIOS.  On this model - brand new T330 - with current, up-to-date BIOS,  there is no such BIOS setting/option.

Looking for a solution.   Had an older USB 2.0 PCI card, but the machine has no PCI slots.  Thinking of trying a USB 2.0 PCIE card.  

What is bewildering is  Dell sells the T330 with NO USB 2.0 compatibility - rendering installation of W2008R2 SP1 difficult and possibly  impossible.  NOTE: this OS is a Dell supported OS for the T330   I would not have purchased if  it was not  supposedly supported (I am restoring  a DC with this OS because of a failed  motherboard on a PE server).
