Man does Windows blow for s/w development.
After loading tools, subversion, winzip, mingw, msys, libusb and a few others
on my XP vm. I was able to build a avrdude binary from the latest svn sources.
It is attached. Rename your existing avrdude.exe and avrdude.conf and replace
them with these.
Your uploads should be MUCH faster.
Ever thought about bringing up a linux box or VM to have
a real development environment?
