The device in question may not be working due to lack of appropriate power to your usb port. Other devices may not require the same amount so in fact work. Did you try unhooking all other devices and run just the current one? Did you try different ports? I assume it's usb powered and not AC adapter? Do your other devices need USB 2.0? If not, this one probably does.
I recently purchased a usb multi-slot cardreader/usb hub. Upon atempting to intall the driver, I was at a screen telling me to plug in the device for it to be recognized. I got a balloon pop-up telling me that "Windows does not recognize the device." After that, the insallation tells me that since the device is not recognized, the installation has been terminated. I tried to just plug it in without the driver and I still get the same message from off the icon on the taskbar.
I have used other usb devices and have had no problems so I figured something might be wrong with the device so I took it over to a friends house and he was able to use it without the driver installed. We then brought over his card reader and hooked it up and we got the same message.
I have checked out the usb drivers and all are working properly. everything is working right and cofigured correctly. I have a Gateway model E2300 using WINDOWS XP HOME 2002 w/SP3. I have a speed of 2.66Ghz I have gone thru Microsoft and Gateway support and they both tell me that the device is faulty. If its at fault, then why does it work on my friends computer and his does not work on mine either. And I have other usb devices (webcam, digital camera) that work just fine? Is there some sort of configuration to the roothub that I need to do in order for this device to work? Is it possible that cardreaders won't work for some reason on my computer?
Sorry this is sooo long but I have been almost everywhere to get some help with this problem.
