    I'm suspecting Linux's partition readings are bogus. SCSI generic devices???

    I'm not even sure IF this is a USB Mass Storage device. Could be the internal chip. And that communication goes over libmtp.

    I'm gonna try adding it's vendor and product id to libmtp, compile it and see if gmtp handles it.

    In the meantime, does anyone have any idea? Or the same device?

    EDIT: Manual mentions Windows XP or higher. Could be an indication of an MTP device. However, mtp-detect sees nothing.

    EDIT2: No dice with libmtp-1.1.3 from Ubuntu by manually adding it to music-players.h.

    Just confirmed with the distributer that it uses USB Mass storage only. So I have opened a kernel bugzilla here in case another soul stumbles on this.
