USB Power Surge on Enhanced Host Controller Problem

[mwieder]

I have a USB Wireless adapter that was working fine on my desktop PC
(XP SP2) for months and recently stopped being recognized. If I
disable the Enhanced USB Host Controller, then XP recognizes the
wireless adapter correctly but it functions only at USB 1 speed. The
moment I enable the Enhanced USB Host Controller in Device Manager, I
get a 'Power Surge on USB Hub' message and the wireless USB adapter
becomes an unknown device. The wireless adapter works fine on all
other machines and I replaced the motherboard on this machine to no
avail, so it seems it is definitely a software problem with XP.
I checked the Bandwidth on the Enhanced Host Controller and the only
listing is System Reserved 10% so that seems fine. The Power info on
the USB Hub yields a attached device (my Microsoft USB Mouse) using 100
mA and 1 port available, so neither of those are the problem/solution.
It is an Intel chipset and I updated to the latest chipset drivers as
well as updating the BIOS last week when this first surfaced, but it
didn't help.
I thought perhaps of deleting the USB drivers from Windows but they
replace themselves at will; I uninstalled the USB hubs/ports, deleted
all the dlls and sys files to do with USB, unpacked the old dlls and
sys files from SP1 and rebooted only to find the newer USB drivers
there with the same issue.
Outside of reformatting my hard drive and reinstalling Windows, can
anyone suggest how to solve this issue with XP?
thanks!

Could you provide one additional piece of information ? Go to Device
Manager, USB category, Open the Enhanced Controller, Driver (TAB)
post the Version and Date Stamp of the Driver. Also, What Vendor,
Model motherboard does your setup use.

The driver is Microsoft 6/1/2002 version 5.1.2600.0
The machine is a Dell Workstation xw4100. Ican't find any brand on the
physical motherboard.

Thanks, I assume you mean Dell Dimension 4100 Desktop ? When
you expand Device Manager USB - What "Exact" descriptor is used
for the enhanced controller ?

oops - not dell - hp workstation xw4100. my bad.
the device reads:
Intel(R) 8280 1EB USB2 Enhanced Host Controller - 24DD

Makes a "Big" difference, don't mind researching on behalf of
posters - but correct info helps.

Anyway - your USB drivers are way out of date. Your PC has
the same Chipset as my Intel 865 - so part of your issue is the
drivers in use. The latest drivers for the USB controllers should
be 7.2.2.101 dated September 2005.

Let me double-Check HP's "Scattershot" website and I'll post
back shortly.

Sorry again about the error. I updated the drivers from the HP page
and those are what I got; also Windows Update didn't find anything
better. If there are new drivers that would be fantastic.

Working/Writing up a "Step-by-Step" on how to update the
drivers, will post in few minutes.

Intel's chipset ID utility claims I have an Intel 875 chipset family
chipset. The Intel download of the latest software for that chipset
says "The Intel Chipset Software Installation Utility provides
_functionality_ for AGP and USB, _not_ AGP or USB drivers."
