Re: Re-Installing USB Stack

I am having real problems with the USB ports on my ASUS p4b533-e (Intel 82801 chipset) running Windows XP Pro (SP2 upgraded from original release XP disk).

Devices keep disconnecting and reconncecting, mass storage devices do not convert to drives and ask for a driver (the devices work fine on my other XP machine), dogs and cats sleeping together. Mass hysteria.

I have read an article at Microsoft about the driver versions (mine seem to be pre-sp1, ver 5.1.2600.0) and would like to make sure that I have the latest USB driver stack.

All articles suggest that I use the update driver button in the driver details tab. This never updates the drivers as Windows update can not find a better driver that the one currently installed.

Everything I read seems to indicate that later drivers were available in SP1 and SP2. I have these SPs installed and yet, I still have old drivers.

Is there a definitive list of the current USB 2.0 drivers and how can I get them to re-install my USB 2.0 stack?

Some points to ponder:

Never get a driver from Windows Update.

See http://support.microsoft.com/kb/873169/en-us

Have you tried to uninstall the USB controllers from Device Manager, and then rebooted to let Windows detect them and install drivers?

Double check your driver versions. If I look at the properties for the first entry under Universal Serial Bus controllers in Device Manage (my Intel 8280 1DB/DBM USB 2.0 Enhanced Host Controller), it indeed shows a driver version of 5.1.2600.0. BUT, if I click on "Driver Details" and look at the driver files (for example usbhub.sys), these all show as "File version: 5.1.2600.2180 (xpsp_sp2_rtm.040803-2158)" That particular file shows a "create date" of August 29, 2002 and a "modified date" of August 03, 2004.

Usually, the place to get drivers is from the hardware manufacturer -- not Windows Update. However, for your mobo, ASUS only has XP USB drivers for use with the Intel ICH4 chipset. And they also say, "If you're using Windows XP SP1 (Service Pack 1) or later versions, you DO NOT need to install this driver, because they already contain software support for USB 2.0."

You should NOT need them, but the XP sp1 drivers for USB 2.0 are at http://support.microsoft.com/kb/822603/en-us
(These files are all version 5.1.2600.1243, so you can see that they're quite a bit older than the sp2 files that I mentioned above).

You might want to poke around http://www.usbman.com/ for further tips/info, etc.
