The kernel usually probes all devices at boot time and places all found into /dev (unless a, say, USB drive is plugged in and identified by e.g. dbus/hal/udev).
If not found in /dev, your device might have a problem.

halmount
halmount(1) User Commands halmount(1)
NAME
halmount - mount and umount filesystems via hal
SYNOPSIS
halmount [OPTIONS]... <device|label> [mountpoint]
halmount -u [OPTIONS]... <device|label|mountpoint>
halmount -e [OPTIONS]... <device|label|mountpoint>
DESCRIPTION
halmount can mount and umount filesystems via hal. Hotpluggable devices and media such as USB sticks and CD-ROMs are typically not entered
into /etc/fstab and are therefore not mountable by normal users via the mount(8) command. Instead hal provides methods to mount and umount
such devices.
Additionally it's also possible to eject devices. For devices like USB sticks eject means the device cannot be mounted again until the
stick is re-plugged, ie a "save remove" feature.
OPTIONS
-t TYPE
specify the file system type to use
-o OPTIONS
specify mount options
-v verbose listing of devices
-u umount specified device
-e umount and eject specified device
-a perform requested mount/umount/eject operation all available devices
--listudi
list UDIs of devices, useful for debugging
EXAMPLES
halmount
list all mountable devices known to hal
halmount /dev/hdc
mount device hdc on default mount point (/media/volumelabel)
halmount /dev/hdc cdrom
mount device hdc on /media/cdrom
halmount -u "Holiday Pictures"
umount device that has the label "Holiday Pictures"
