Anyway, i found a solution somewhere on anythingbutipod forum:
"Trying backing up /usr/share/hal/fdi/preprobe/10osvendor/20-libgphoto2.fdi and removing any references to your Sansa player. If that does not work, then move the file out of the 10osvendor directory and try plugging in the Sansa again."
I moved the file and now i see my sansa in nautilus :).. Oh, and i'm using latest rockbox so i can see my 8GB microSDHC card, too.
First, sorry for messing with status.
