Asus A8V-E Deluxe and USB ports not working proporly

Hi,

I have installed an Asus A8V-E Deluxe (BIOS 1011) in my HTPC using Windows
Media Center 2005 (including rollup package 2 update) and the VIA Hyperion
5.07A driver set. The chipset cooler has been replaced by a Zalman ZM NB47J
heatsink in order to reduce noise and the board is equipped with an AMD
Athlon 64 3000+ which is cooled by a Thermalright XP90. The system is
powered by a Seasonic S12 380W PSU. Nothing is overclocked and everything
seems to be running at decent temperatures (it is very stable and has never
craches unexpectedly). Cool & Quiet is enabled and I have installed Asus
Cool & Quiet Utility v1.022 and AMD CPU Driver v1.2.2.0 in Windows.

I have a couple of problems with this motherboard though:

First, if the mouse is connected to the PS2-port the PC will not enter S3
standby or hibernate - even though no one is touching the mouse while
waiting for the PC to enter power saving mode. BIOS option "PS2KB wakeup
from S5" is set to enabled (there is no changes if this option is disabled),
"PS2MS wakeup from S5" is disbaled and "Power up on PCI devices" is enabled
to facilitate Wake-on-LAN. Moving the mouse to a USB-port on the rear solves
the problem. Now the PC enters S3 standby and hibernates according to the
settings in Windows' power management scheme. This solution is acceptable
had it not been that I sometimes loose the connections to my mouse and
Microsoft MCE remote control (which is also connected to the rear USB-port)
after watching a film for a couple of hours forcing me to use the keyboard
(which is connected to the PS2-port) to reboot. After reboot, the mouse and
remote comes back on.

Second, I am having trouble reading, booting and even formatting floppy
disks using my Samsung SFD-321U/KJB USB1.1 floppy drive. This goes whether
the drive is connected through the front or the rear USB-ports. Actually, if
the PC has been turned off for quite some time (e.g. half an hour or so),
sometimes I am able to boot on the first try (using the F8 boot menu). But
after a minute or two of operation, that is no longer the case. Windows is
almost always unable to read the floppy disks and suggests to format them,
but without being able to complete a format. The drive and the disks have
been tested on another system without any problems.

Now, I am not sure what to conclude from the above, but I have read that
other people have had quite some problems with the USB-ports on this
motherboard. Most of them however has been related to USB 2.0 compability
issues which shouldn't be the case in this instance (and the USB 2.0 drivers
seem to load fine in Windows) since neither my old Logitech cordless mouse
nor the Samsung drive is 2.0-devices (I am not sure about the Microsoft
remote control but I doubt it's a 2.0-device). This has been mentioned by
XBit Labs in their review of the board
(http://www.xbitlabs.com/articles/mainboards/display/asus-a8ve-deluxe.html).
Other (http://hardware.mcse.ms/archive69-2005-8-227584.html) suggest that
some boards come with flawky south bridges (since reading the latter article
I haven't taken the time to identify the manufactoring date of my own south
bridge so I currently don't know whether this could be an explanation).

I guess I am looking for people out there having similar problems with their
USB-ports on this motherboard and of course if any of you have been able to
fix them. Can the theory on flawky south bridges be confirmed?

Regards
Anders
