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 !
