Hey I'm having a weird problem. I have a Dell Dimension
8100 that comes with the standard 4 USB 1 ports. I just
bought a ALI USB 2.0 PCI card, it's 4+1 ports. I installed it
and installed the drivers no problem. The only problem is
that it seems like only USB 1 devices work. Mice,
keyboards etc work fine. I put in a memory key and it
transfers only at USB 1 speed. As well when I plug in my
ipod it says error reading device and says it needs to be
formatted but when I try to format it says windows cannot
format. I had it working once but it transfered about 1mb
every 30 seconds. It's weird because it installs a device
caleld USB 2.0 ROOT HUB, and then like 5 USB ROOT
HUBs. When I attach a device, it shows it connected to
USB ROOT hub. Shouldn't they all be USB 2.0? It doesn't
let me select that or anything though, if I try to update
their drivers the only one that works is USB ROOT HUB.
The drivers for the card are only a setup exe program so I
can't manually select the driver. Anyone know what might
cause this? Thanks so much.

I've seen similar problems when mixing USB 1 and 2. I would uninstall all the USB drivers and devices, reboot and enter BIOS, disable the onboard USB 1 controllers, boot and see if XP automatically installs the drivers for your USB 2 card. If not, then try the install CD again.

this should sort you out :)

Okay I'll give that a try. I did try disabling the USb 1 in
bios but I don't think I had uninstalled the drivers first. I'll
uninstall everything, reboot to bios and then disable it. I
think it will auto install even though I click on uninstall
driver though but we'll see. It's weird because after the
CD installs the drivers it says a window will pop up saying
new hardware found and then you have to click I'll install
the driver myself, and then choose USB 2.0 root hub from
the list. That happens and I do it, but it only does it for
one, the rest are all USB root hub in device manager.
When I right click properties for them, it shows things like
2 ports avalable, or logitech mouse on 1 port, 1 port
avalable. But when I right click properties for USB 2.0 root
hub that it instaleld, it only shows drivers, resources.
Nothing about power or devices attached, but I'll try
thanks.

No unfortunately that doesn't work. It's still only USB 1,
transfering a 1mb file to my memory key took about 30
seconds, so I don't know what's wrong with it. I'll
probably just return it.

I take it back I'm sorry it works now! I'm not sure about
ipod, but I found my 512mb memory key and it transfered
10mb in like 3 seconds. The 64mb kingston one I have
must not be USB 2.0. Thanks for your help!

I've got exactly the same problem with my card Ali USB2. I uninstall the driver as you command and then I disabled onchip USB1 form the BIOS. Unfortunately it still doesn't work.

It still too slow.

Is there another way to uninstall the driver than the one from device manager?

is it really onchip USB1 I must disabled?

please help !
