I'm using OpenWrt tool to build my system. I was working with the SAM9x60 board, but I just changed to use the SAMA7G5 eval board. On the OpenWrt Menuconfig, the USB kernel modules page is completely empty. Anyone knows why Menuconfig is no loading USB Kernel modules for this board? and what can do to load them? Inside the Kernel Modules, the USB category is the only one that is empty. Any hint on how can I load those modules.
