How do drivers work in Linux?

Linux drivers are built with the kernel, compiled in or as a module. Alternatively, drivers can be built against the kernel headers in a source tree. You can see a list of currently installed kernel modules by typing lsmod and, if installed, take a look at most devices connected through the bus by using lspci .
