"USB Device Not Recognized" in USB2 ports but is recognized on USB1ports

I bought a new USB2 PCI card and am having some problems using it.
I've plugged it in alright and I'm able to successfully plug in a USB
optical mouse into each external USB port on the PCI card and it works
in each and every one of them. Same thing with a 128MB USB stick.

Both of these also work in the USB1 ports I have on the front of the
computer.

The problem I'm experiencing occurs when I try to plug a USB HDD
enclosure into the USB2 ports. It works just fine in the USB1 ones
(the computer reacts much as it would when a USB stick is inserted
into it). When I plug it into the USB2 ports, I get the following
error:

----------------------------

USB Device Not Recognized

One of the USB devices attached to this computer has malfunctioned,
and Windows does not recognize it. For assistance in solving this
problem, click this message.

I click on it and get a useless "Try reconnecting the device. If
Windows still does not recognize it, replace the device."

----------------------------

My question is... why?

Why would something be recognized by USB1 ports but not by USB2 ports
added by a PCI card?

I'm running Windows XP SP2.

I just this with an 8-in-1 card reader and got the same thing.
Doesn't work in USB2, works fine in USB1...

I've had this problem some time ago. Turned out the USB 2 add-on card
was slightly not compatible with my system. I had a USB 2.0 add-on
card based on ALi USB chips and it cause a lot of problems (loss of
USb 2 port, loss of wireless networks and PC not start.) I have since
replaced then and all seems to be ok.

Hi there,
I had this exact problem a few weeks (months ?) ago and spent endless hours
trawling the net for solutions. I found pretty quickly that literally
hundreds of people were getting this error message at random times when they
attached random external devices, for no obvious reason.
Anyway, cut a long story short, after following zillions of bits of good
advice and getting no solution, I got the following bit of advice and it
worked instantly. It lets you see all the devices that have been on your PC
in the past and are still hanging around like ghosts causing problems.
basically you uninstall the whole lot, reboot, and let the OS reinstall the
'good guys'. Work a treat for me after days of stress. See following :
(It's designed for people who are not necessarily very 'IT Literate' so
please don't feel patronised :-)))
**************************************************
Open a command window : Click on START/RUN then type "cmd" (without the
quotes) and click OK A black window will appear with some writing on it.
Leave the cursor exactly where it is and type (without quotes) :"set
devmgr_show_nonpresent_devices=1"and press return.Another line of typing
will appear, the same as the previous one.Now type the following and press
return. "start devmgmt.msc" This opens the device manager but with a twist.
From the 'View' menu select "Show hidden devices". Device manager will now
show you every device that has ever been connected whether it is present or
not (non present devices are greyed). Now you should be able to find all
your devices that don't work and delete them (it doesn't matter if you
inadvertently delete a working device). This will allow Windows to redetect
them when you connect them and reinstall them. To cleanup the USB devices,
scroll to the bottom and click on the '+' next to 'Universal Serial Bus
Controllers'.Right-click on each item, except the first few at the top which
are called 'Host Controllers'.When you right-click, you will be given a
menu - choose 'uninstall, and click OK.When they are all gone, you will just
have 3-4 Host Controllers left.If there are any other devices, apart from
the USB devices, that have a yellow or red exclamation mark or question mark
against them - they also have a problem - have a look and also uninstall
those items. Close the window, and the black 'cmd' window. Reboot.As the PC
boots up there will be a few 'bubbles' in the bottom left-hand corner of the
taskbar, saying 'Found New Hardware'. Don't press any keys, just leave it a
few minutes to finish re-installing everything.All
done.**************************************
let me know how you get on. Carole
