Problem with usbconfig, not working

It seems usbconfig is not working for me (-CURRENT from Jan 29, amd64)

What i'm trying to do is turn off power to a usb device (actually i  
wanted to turn off all ports, no matter if there was a device there or  
not)
For all commands I get the error message: "No device match or lack of  
permissions."

Also imo its not really clear in man usbconfig what -u and -a should  
be. What should it be for ums0 at uhub0?
-u 0 -a 0		(uhub0 usm0)
-u 0 -a 1		(from usbdevs output: /dev/usb0 port 1)
-u 0 -a 2		(from usbdevs output: /dev/usb0 addr 2)
I tried all, same error message. I also tried without -u and -a, same
