Im thinking its something to do with Fiesty Fawn, cos it happens to me ever since i upgraded. I knnow the udev version is newer than expected which might have an effect. The .deb version sometimes charges if i connect the bb then remove it straight away remove it then connect it again straight away. How fast this is done effects the chances of this working in my experience. The CVS version doesnt seam to work atall for me at the moment. When i have more time il look into it more.
