Did you try connecting the port with the PC off and then turn on, did it include a driver CD?

it did not include a driver cd and when i connected with the pc off it would not allow me to switch on -the switch would not work-as soon as i pulled the usb connection out the pc i was able to switch on and boot up normally.

I'm still trying to figure this out, sounds like a hardware problem, i.e if the USB hub is taking the power then there could possibly be something wrong with your power supply, or can you try to connect the old usb port, and then connect the new one the the 4 port hub and see if that happens, it could also be the USB controller driver.

Is this a powered hub?  (i.e. does it have its own power supply)

If not, that's the issue.   A single USB port simply doesn't provide enough power to split among 7 devices.

it has its own power supply -i took the 7 port off and replaced it with the original 4 port and this worked ok.no problems.

You most likely simply have a defective hub.   Return it for a replacement.
