USB problem isolated!!
southpaw13:
I hope. I tried my LEDWIZ on a VIA chipset and it worked fine! It does not work on any of my NVIDIA chipset computers!
Does this help?

Were both the 2000 and xp machines Nvidia CK804 chipsets? I noticed today that the Athlon I had the problem on was an Nvidia too.
I'm seeing the problem on a 82801 Intel and a hub.
Did you try reproducing the problem with the LEDWiz control panel or PowerMAME?
southpaw13:
I will have to check the actual chipset numbers, but I did the testing on the LEDWIZ control panel...
Both of my first system tests were on the NVIDIA chipset.
The third one I tested was on a VIA....
It worked fine!
All of my tests were done on Athlon XP CPU's...
southpaw13:
What's the easiest way to find the chipset number with cracking open the case or the instruction manual?
I really think that root problem is Via vs. Nvidia since they handle things differently...
Can anyone confirm this?

JoyMonkey:
I've also just hit the problem with an NVidia chipset (on an Asus A7N8X-E motherobard). In the device manager it appears to be using the standard Windows generic USB chipset driver (see attached). NVidia (or perhaps Asus) should have some more specific USB 2.0 drivers for my motherboard, maybe I never installed them? I'll have a look shortly...
