problems getting kindle fire on Fedora 17, help

view story

http://forums.fedoraforum.org – First off I can say that my android tablet is recognised as mass storage device right off and I can access it through dolphin. However nothing happens with my daughters kindle fire hd. I have had partial success copying books/docs with calibre. I have mixed success with mtp but I am not sure if I am setting up mtp etc right. I can get the kindle fire recognised by mtpfs /mnt/kindle and I can see the mountpoint in dolphin. When trying to copy files I get error message about can't change permission and nothing is copied. I have mess around with various permissions but no good. Any advic (HowTos)
