Help needed: DX38BT USB port issues

[simonjester]

Hi! First time poster looking for a little help. I'm building a system around an Intel DX38BT motherboard. I was able to install XP fine. After I installed the MB device drivers and rebooted, the USB ports became unresponsive. I can get into and manipulate BIOS fine, but once the bootcodes disappear it seems like all the USB ports lose power - the numlock on the keyboard and the laser on the mouse go out. Windows boots, and hitting the power switch causes Windows to initiate a shutdown, so the system isn't locked. I've tried the following:

• Booting from the DVD drive - system doesn't respond to KB at the "Press any key to bood from CD" prompt.

• Tried all available USB ports

• Removed all non-essential hardware (including FP USB ports)

• Reseting BIOS to "Optimal" settings

• Resetting BIOS using the HW jumper

• Removing all hardware and reseating the motherboard

• Replacing the CPU (longshot, but I had a spare Duo laying around...)

None of the above helped. I'm leaning towards "there's an issue" with the mb, but can't explain why installing new drivers in Windows would cause the issue. ...am I totally barking up the wrong tree?

I was able to determine two issues:
1. Not sure how but someone (cough cough) disabled Legacy USB setting in BIOS
2. The windows drivers that come with the MB are no good

Once I enabled Legacy USB I was able to use the kb / mouse to *select* Safe Mode (but not use) or to boot from the install CD, but because the Windows drivers either didnt load or didn't load correctly the USB ports lost power sometime during the Windows boot rendering the kb/mouse useless.

I reinstalled Windows (and didn't install the USB drivers!) and everything's fine
