How to build a kernel with specified modules?

[Joris Giovannangeli]

Hi,

you probably want to use

"bus/usb/usb bus/usb/ehci" to build usb and the ehci controller.

Please note that usb is the old usb stack, for the new one, you need :

"bus/u4b/usb" and for instance, if you want to build the ukdb for usb
keyboard, "bus/u4b/usb/input/ukbd"

To answer more generally, you need to specify the path to the module
directory. the module directory is usually an empty directory containing
only a Makefile with a KMOD=modname declaration.
