Use lsusb to find the device ID, as the case for me,
05ca:1839It is reported as a Ricoh R5U870 webcam, the driver is not preinstalled, among all the online drivers provided, the following one works, containing no compiling error and it has enabled the camera perfectly.
I quote the installation instructions here,
$ sudo apt-get install libglib2.0-dev libusb-dev build-essential gcc automake mercurial $ hg clone http://bitbucket.org/ahixon/r5u87x/ $ cd r5u87x $ make $ sudo make install $ sudo r5u87x-loader --reloadIt recalls me of my experience on enabling the wireless function on a DELL Inspiron long ago. As ubuntu is designed to be universal, it still faces both legal and technical issues to include all possible drivers. This requires the holders of proprietary drivers to consent the public use such as in a Ubuntu release.
