I'm working remotely and I can't plug or unplug anything right now, but 
this looks strange.

-bash-3.00# usbstats
Controller /dev/usb0:
         34 control
          0 isochronous
          0 bulk
          0 interrupt
Controller /dev/usb1:
         93 control
          0 isochronous
          0 bulk
         27 interrupt
Controller /dev/usb2:
         34 control
          0 isochronous
          0 bulk
          0 interrupt
Controller /dev/usb3:
         34 control
          0 isochronous
          0 bulk
          0 interrupt
Controller /dev/usb4:
         49 control
          0 isochronous
          0 bulk
          0 interrupt

Looks like interrupts are only firing for the one controller that 
consistently attaches devices. There are devices attached to at least 
one port on every hub.
