MOを利用可能にする方法を以下に記述します。

システム -> システム管理 -> パーティション・エディタ　を起動する。

このPCに接続されているstorageの装置番号を確認する。
Windowの左上、GParted -> デバイス -> /dev/sda から /dev/sdz

MOの記録容量から表示装置番号 /dev/sda から /dev/sdz の中から装置番号を特定する。
今回 /dev/sdc であるとする。

アプリケーション -> アクセサリ -> 端末 を起動する。

MOのマウントポイントを作成する。
$ sudo mkdir /media/mo

MOの自動マウント定義を設定する。
$ sudo gedit /etc/fstab

geditテキストエディタの最後の行に以下を追加する。
/dev/sdc /media/mo auto rw,user,noauto,owner 0 0

手動マウントを行う。
$ sudo mount -a

Desktop上にMOのアイコンが表示される。

詳細は下記URLを参照してください。

ハードウェア:MOドライブを使うには？

パーティション・エディタが起動すれば良いのでメニュー内を探してみてください。

上記がUSB端子を取り付けた状態と取り外した状態です、意味が分かりません、宜しくお願いします。

先ほどの返信後、気がついたのですが、
USB経由でも、MOドライブを繋ぐと、scsi デバイスとして認識される筈ですよね？
例： 私の環境で、USB経由で、DVD-R/Wドライブ繋いでみました

それに、デスクトップ、パネル・メニューの「場所」に、「CD-RW/DVD±RWドライブ」が追加されました。
これが出ないと言うことは、現状のシステムでは、使えないかも知れませんね。

そこで、最後の確認として、USBハブにMOを繋いでいるように思われますので、
マザーボードのUSBポートに直接、MO  繋いで dmesg を見るとどうなりますか？
（考え難いですが、ハブに阻害されている可能性も無いとは言えないので）
