All USB? Even your keyboard and mouse?

If the keyboard works, try zapping the PRAM: on a cold start (not a restart) hold down Command-Option-P-R until you hear two startup chimes.

Got the keyboard and mouse working with startup so it must be my USB hub. Is there anything I can do for the hub or is it dead and i have to get a new one?

First, if it's a bus-powered hub (draws its power from the computer), I'd recommend buying a self-powered hub (plugs into a power outlet).

If you want to keep your hub, as a workaround maybe try leaving it unconnected at startup and then plugging it in.

Is it a new hub, did you recently add a new device to it, or did these startup hangs just suddenly begin on their own?

Did you try zapping the PRAM?

One more thing: the hub should not be plugged into one of the ports on the keyboard. Plug it into a port on the iMac itself.
