Using AVRISP II on Windows

Hi Guys,

I trying to get a USB AVRISP II going on Windows but I don't seem to have
the command line right but can't see from reading the docs what O have got
wrong. 

This is the command line I'm using:  

        avrdude -p c128 -P usb -c avrispmkII -vvvv

This is what I get:

C:\WinAVR\bin>avrdude -p c128 -P usb -c avrispmkII -vvvv

avrdude: Version 5.3.1, compiled on Jan  1 2007 at 14:25:19

         System wide configuration file is "C:\WinAVR\bin\avrdude.conf"
         User configuration file is "C:\WinAVR\bin\avrdude.rc"

         Using Port            : usb
         Using Programmer      : avrispmkII
found 4 busses
avrdude: usbdev_open(): did not find any USB device "usb"

Cheers
