Windows Vista Build 5384.4, Asus P5WD2 Premium & ALC882 HD Audio

I have an Asus P5WD2 Premium motherboard that incorporates the ALC882 HD
audio codec, i have tried installing the last (5254) and latest (5265) beta
drivers downloaded from the Realtek website for Windows Vista Beta, i have
also tried the Windows XP drivers (1.37, 1.38 & 1.39).
The problem i am having is when i install any of the ALC882 HD drivers my
USB keyboard locks up (stops responding) at the Windows logon screen , even
if i restart the system, also my USB mouse sometimes has the same problem.
If i restart the system in to safe mode my keyboard works fine but stops
responding again once i boot back in to normal Windows mode, if i uninstall
or disable the Realtek controller from device manager in Windows safe mode
then my keyboard starts to work normally again, this issue is not pressent
with Windows XP Pro/Home, this is a Windows Vista only issue.

Can anyone shed some light on this issue and also is this a known problem or
is it just me with this issue?

I have listed below any system specs that may be relevent, bios version, and
drivers that have been tested to try and solve this issue.

Same mainboard and bios. And same problem with Logitech cordless desktop mx
and I try the same combination of drivers
with no success.
Hernan Vega.

 

I have the P5DL2 keyboard, which is similar to the P5WD2, and had the same
problems with the 64-bit version of Vista Beta 2. After my FOURTH attempt at
installing the OS, I was finally able to install the audio drivers I used in
XP Professional x64. The mouse and keyboard did stop responding initially,
but after some plugging and unplugging of the USB connector, I got both to
work!

You guys may want to try that.
