If there's no g_ether module then it will be built in, and g_file_storage may 
be. If so you can use the bind and unbind /sys files for the drivers instead 
of loading and unloading them. I don't remember exactly where they live, but 
it's probably something like:
	echo g_ether > /sys/bus/usb/drivers/g_ether/unbind
	echo g_file_storage > /sys/bus/usb/drivers/g_file_storage/bind
There is similar mechanism for setting the parameters, but I don't remember 
the details. Look for suitably names files in the g_file_storage directory.

Device mode is when the moko behaves as a usb device like an ethernet adapter 
or a flash drive. Host mode is when the neo behaves as a usb host so you can 
plug in and use devices
