2.6.24-rc1 / powertop-svn: See which USB devices causes wakeups?

[Peter Ganzhorn]

Hi,

with 2.6.24-rc1 and powertop from svn (2007-10-28) I still can't see 
which USB devices keeps producing wakeups:

49.3% ( 20.0)     <kernel core> : usb_hcd_poll_rh_status (rh_timer_func)

I think Arjan said that with newest powertop and 2.6.24-rc* this should 
be possible because some patch to add this functionality was merged into 
2.6.24.
So why can't I see which USB device is causing the wakeups or what am I 
doing wrong???
