What are the other modes available on the clip+? If I'm not mistaken, you
want mass storage mode.
In mass storage mode, provided your kernel and udev is configured
correctly, it should be detected (check the kernel logs, aka dmesg, just
after plugging it in), activating the mass storage driver, which will
detect the partitioning. That will in turn activate udev to make
available the device as a /dev/sdX device, with all the partitions, if
any, available as /dev/sdXY, where X is a letter and Y is a number (like
any other scsi system based block device,
pata/sata/scsi/usb-mass-storage/whatever, only the old deprecated ide
drivers use /dev/hdXY any more). What happens after that (automounting,
or simply available for you to mount manually) will depend on your fstab
and hal config, etc.
Mass storage is by far the simplest mode to work with and troubleshoot.
The other mode, media device or whatever, uses much lower level kernel
drivers, usb and bit-banging or some such, with the higher level interface
being userspace. Generally, only specific media apps (such as amarok,
with the appropriate USE flags, I assume there's a gtk/gnome media app
that supports that too) with the userspace support built-in will be able
to deal with devices in that mode. In media mode, the device will not
normally be available in a file manager, etc, as it isn't exposed as a
block device, except in mass storage mode.
