When i connect my Windows Mobile 6.1 device with my WIndows Vista computer, only autoplay opens up, and my device is treated as a mass storage device, and not a portable device. I managed to start a partnership once, but i had to end it after an error. Before that, i had also some errors, but i somehow managed to partner it. After that, i could not partner it anymore, as it opens up like another USB mass storage drive.
