To be quite honest I did not. I was hoping "-P usb" on the command line
would be all what's needed.

After you posted the reply I looked into libusb-win32 and how to apply
it to avrdude.

Using avrdude with USB on Windows seems more complex than I thought as a
driver has to be installed first and as I understand Atmels USB driver
for the JTAGicemkii needs to be uninstalled.

Q: Which of the two libusb-win32 drivers (filter or device) shall be used?
Q: Can libusb-win32 coexist with Atmels jtagicemkii USB driver or needs
the latter one to be uninstalled?
