Kmod Manager is a handy utility to easily load and unload linux kernel modules in a rooted android device. This requires busybox to be installed on the device. Kmod manager will automatically load the dependent modules and unload them when they are not needed anymore. Currently KMod Manager will look for modules only in ‘/system/lib/modules’
Note:- Some busybox on the market has issues with modprobe applet. This has been tested and found working with busybox binaries from most of the custom roms ( CM , Omni and their derivaives ). Busybox from Stephen is also having issues now ( top rated busybox installer on the google play). Please use BusyBox installed from JRummy Apps
Please note that your kernal will need to be compiled to enable the modules, you can then use this app to insmod and rmmod
