My zen mozaic mp3 player mounts fine but the operation system recognizes it as a digital camera. That wouldn’t be a problem as I can browse the folder but I cannot copy anything on it.
I guess I have to access it as a root or maybe make the system recognize it as an mp3 player but I don’t know how.
You say you can “browse” the file system on the device, but can not copy files to it. Did you check if it is mounted read-only. Or if there is anything in the ownership/access bits that block you.
In other words, what did you do to check what is going on beside using some GUI file manager (Dolphin?)? E.g.
You would probably like to manage this from within Rhythmbox, or whatever audio player you are using.
simply create the hidden file “.is_audio_player” in the same location as the music on this thing, remount it and you should be able to manage your music.
