ROS(melodic)でカメラが映らない

前提・実現したいこと

詳説ROSロボットプログラミングを参考にROSについて学習中で、5.2.4 rqt_image_view の項をやってカメラの映像を見てみようとしています。

発生している問題・エラーメッセージ

rqtを見てみても/image_rawには画像が出ません。トピックは出ているのですが。

次に検索すると、melodicからはUVC_camereはlibuvc_cameraになったとのことで、やってみましたが、ダメ。

もちろんimage_view image_view image:=/image_raw でも映りませんでした。

usb_camera もダメ。

何がいけないんでしょう。VMware toolsはしっかり入れているはずなのですが。
