When I install the chipset driver, my USB ports stop working

Hi,

I'm building a system for a friend.  Here's what's in it:

 - Intel DP35DP Motherboard
 - intel q6600 2.66
 - Transcend 2GB 240-Pin DDR2 800 RAM CAS5
 - 2 X Western Digital Caviar SE16 320 Gig
 - Koutech 4-Port FireWire 1394a/1394b PCI Express (x1) Card
 - Rosewill RD600N-2DC-SL-SLV ATX Form Factor 12V V2.2 / 12V 600W Active PFC Power Supply
 - EVGA 256-P2-N412-LR GeForce 7100GS 256MB GDDR2 PCI Express x16
 - 2 X SAMSUNG 20X DVD±R DVD Burner Black SATA Model SH-S203B

Here's the problem.  I install Windows XP Home on the system.  Everything works fine until I install the chipset driver.  When the machine reboots none of the USB ports work anymore.  This really sucks because the DP35DP doesn't provide PS/2 mouse and Keyboard support... only USB... so I'm not able to do anything after I install the chipset driver.  I've tried installing the Chipset driver first, middle and last and it makes no difference... as soon as it's installed the USB port don't work... I get no power to either mouse or keyboard.  I initially thought that this was a bad Motherboard and sent the first one back... got a brand new one and get the same problem.  

When installing the operating system I needed to create a custom windows install disk fdor the SATA drivers.  I got a pack of drivers from this site:

And slipstreamed them all into the install.  I mention this cause I suspect a driver conflict... Is this possible?
