module-assistant is the tool to help to compile module-source package
into binary kernel module , and then pack into a Debian package. So
that you could install/uninstall through the package management
system(dpkg).
The generated package is placed in /usr/src . If you build with the
argument "auto-install" , it will be installed automatically. It is
recommended (and the most simplest) way to install kernel module in
Debian system. Moreover, the generated package works with a specific
kernel version only. That means the package should be rebuild after
kernel upgrade.
However , Debian may not be able to provide the most updated module
source. Just take UVC as an example, the most updated revision no. is
132 at this moment , but the module source package in SID could only
offer rev 120. If you need the features provided by the most updated
revision , then you need to install by source through the svn command
, and then build by the command 'make` & `make install`.
