First off, my PC is a Dell Dimension 2400 (purchased in 2004) running Windows
XP Home Edition, Version 2002, SP2. I've had a recurring problem with Windows
not recognizing my iPod mini when I plug it in (i.e., standard "USB device
not recognized" pop-up balloon) over the past year or so. Thinking it was a
problem with the iPod, I bought myself a Creative ZEN mp3 player for
Christmas, only to have the same problem after the first few times plugging
it in. (I returned the ZEN b/c I couldn't stand the interface and software
compared to iPod/iTunes, but that's neither here nor there). What's weird is
that it's worked fine before, and occasionally still does, but most of the
time I just get the above-mentioned "USB device not recognized" message.
I've been researching this online for the past few days and came across an
old 2004 post from a forum I can't recall the name of, but it describes my
current situation perfectly so I'm just going to quote it directly:
"Every time I plug [my iPod] in, Windows' new hardware found device just
pops up a balloon saying that the USB device is not recognized. iTunes
doesn't recognize that iPod has been connected to the computer, and I don't
see it as a hard drive under My Computer....Under Device Manager/Universal
Serial Bus controllers, I have nine entries: "Intel(R) 82801DB/DBM USB 2.0
Enhanced Host Controller - 24CD," three "Intel(r) 82801DB/DBM USB Universal
Host Controller" suffixed 24C2, 24C4, and 24C7, respectively, and four "USB
Root Hub" devices. I tried uninstalling them and rebooting on the hopes that
when Windows reinstalled them after I rebooted, the problem would go away,
but no such luck.
I did find, however, when I disabled the first entry, the USB 2.0 Enhanced
Host Controller device, my computer was suddenly able to detect the iPod for
what it was. But without that 2.0 controller, it could only connect at 1.1
speeds (and the little popup balloon showed up again to tell me that I was
just connecting at 1.1). And then, after renabling the USB 2.0 Enhanced Host
Controller, all the devices got reinstalled and the iPod again could not
connect. Something seems to be wrong with that USB 2.0 Enhanced Host
Controller, but I tried to update the driver and Windows said it couldn't
find anything new or better. Does anyone know what I can do to fix this
problem?"
So that's the gist...I currently am able to connect my iPod, but only by
disabling the USB 2.0 Enhanced Host Controller. It doesn't bother me that
much to have to do so, but what is bothersome/annoying is that this appears
to be a common problem and there must be some kind of fix out there that
Microsoft or other folks have used. I tried installing a hotfix referenced in
Microsoft Article 892050 (http://support.microsoft.com/kb/892050/) ("A USB
device that is connected to a USB 2.0 hub is not detected in Windows XP
Service Pack 2, Windows Server 2003 Service Pack 1, or Windows Server 2003
x64 versions"), but it didn't solve the problem. I also went to the Intel
website, found available updates/drivers for my chipset (Intel[R] 845G
family), and installed Chipset Installation Utility 6.3.0.1007 (dated
12/16/04). Again, this installation did nothing to fix my problem.
I'm completely at a loss and am tired of spending my holiday weekend working
on this. Right now I'm resigned to simply working with the USB 2.0 Enhanced
Host Controller disabled, but thought I would check here as a last resort.
Thanks in advance for any advice!
