If the driver is not listed here, but the name of the module is known, the "FIND" command can be used to search for a loaded module. If the driver is not in the core and the name is not known, it is possible to obtain a list of all available modules by launching "LS -R/Lib/Module/" Uname -r "/Core" where the "USAME" is replaced by the computer version.

As soon as the name of the module is set, the "LSMOD" statement launches in the listing of all the loaded modules. With a little luck, the controller module will be loaded, but if not, use "modprobe" to try to load.
