As Mike pointed out, it is a hyper-threading problem. The reason for winXP
not working, but W2K works, may very well be that W2K does not support
hyperthreading feature, but WinXP does. I wonder if Mike or anyone does
indeed disable the hyper-threading feature to test without the patch first.
If the driver works without the patch works just by disabling the
hyper-threading feature, we can truly conclude the only issue is the
hyper-threading.
I have already removed winxp a while ago, so I cannot test that. I have been
deterred from upgrading to windows 2003 because of the usb driver issue.
Win2003 indeed supports hyper-threading. However, before I dive into
installing win2003, I wonder if anyone has proved that the winxp will work
with the hyper-threading feature disabled (usually from the bios) without
the patch.
