I’m using OpenSUSE-11.4+KDE and have not been able to access my Sansa Express drive. I can pull it up part way, but it acts as read only. I’m not sure what settings I may need to make in the Partitioner to fix this…
If I boot into a LiveCD of LinuxMint10-KDE and plug it in it is instantly identified as a “Media Device,” and I have access into the MTP section of it I believe.
I prefer using Banshee, but will use Dolphin to manual drop files it I can get the Sansa drive to operate as with Read+Write.
I’ve seen this device listed here at “plug and play” http://en.opensuse.org/HCL:Gadgets#Media_Players
