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
Copyright (c) 2000-2005 Brian Dean,

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.
