What speed is the USB port on your laptop? Is it 2.0? or 1.0?
Try reinstalling the usb drivers on your laptop. Make sure all udb devices are unplugged. Go into the device manager (right click my computer select properties, select hardware, click device manager.Delete all the usb listings under the Universal Serial Bus Controlers heading. Then reboot your computer all the drivers will be reinstalled then connect your usb multi port unit to your laptop.
What is the brand and model of the laptop you are trying to connect to?
Are you saying that everything you plug into the usb port gives you that error?

computer still freezes when the usb hub port is attached

Hello guys,
This problem is happening to me as well. I have a compaq evo n610c (win xp and 1,25Gb ram) and I bought a external hard drive seagate with 500Gb. However when I plug it on my usb port, after about 1 minute my computer freezes.
I tried everything (re-install drivers, change the usb drivers to win xp standards) and I realized that when I disable the "NEC PCI to USB Enhanced Host Controller (B1)" it works fine but with no USB 2.0 support (it is impossible to transfer big files to my external HD).
