which is the cause of interrupts

Hi,

Powertop 1.5 tells me:

Wakeups-from-idle per second : 1161.0
no ACPI power usage estimate available

Top causes for wakeups:
  49.3% (898.0)       <interrupt> : ehci_hcd:usb1, uhci_hcd:usb8, wcfxo
  20.1% (366.4)       <interrupt> : ide0
   7.4% (135.0)               bot : schedule_timeout (process_timeout)

Now how can I find which device is triggering those "ehci_hcd:usb1,
uhci_hcd:usb8, wcfxo" interrupts?
