[avrdude-dev] avrdude - usb - jtagmkii - windows no workie

[Pink Boy]

Umm..
 
I'm having a problem getting avrdude to talk to my AvrjtagmkII
under winders.  Below is the command string and the error message
I receive.
 
---
 C:\WinAVR\bin>avrdude -c jtagmkII -pm16 -P usb:xxx -v
 
 avrdude: Version 5.1

          System wide configuration file is
 "C:\WinAVR\bin\avrdude.conf"
 
          Using Port            : usb:xxx
          Using Programmer      : jtagmkII
 avrdude: ser_open(): can't open device "usb:xxx": The system cannot
 
 find the file specified.
 
 C:\WinAVR\bin>

So what seems like is happening is avrdude accepts the correct 
programmer jtagmkii from the command line and the 'port' in this
case usb:xxx.
 
However, the error message appears like it's coming from the 
serial port init routine, not the usb init routine.  Because the
of the 'ser_open' bit.  As opposed to the error from usb_libusb.c
 
    fprintf(stderr, "%s: usbdev_open(): did not find any%s USB 
    device \"%s\"\n", progname, serno? " (matching)": "", port);
 
Umm....
 
Reading the code jtagmkii.c is looks like it compares the first
three characters of the 'port' option with 'usb' and if true then
sets ser_dev to usb_blah.  So I would expect that I shouldn't be
getting the ser_open() error, but I do.
 
So this means either it seems, that
 
a) There is no support to USB under winders, at least for the 
   jtagmkii.  (I suspect)
b) There's a bug in avrdude. (maybe)
c) I ain't doing something right. (most always)
 
Anyone have an idea of which it is?
 
Note: My jtagmkII works with avrstudio with usb.  Avrdude on my 
system works with a third party stk500 clone.  I get the same error
on my other computer at work.
