Hmm well this has few issues though: 1. We've had USB as loadable modules for years now to cut down on bloat and try to make things more distro friendly 2. MUSB has never worked well with PM and enabling it almost certainly would break PM for multiple devices 3. The USB gadget configuration should be done using configfs as it's device and policy specific and Ethernet gadget may not be even desirable So I suggest just doing what distros do and use a proper initramfs :) BTW what works quite nicely for devices with Ethernet controller is to have u-boot load dtb, kernel and modules.tar.gz over Ethernet and write it to mmc. That way the loaded kernel and modules are available on boot as long as some init script untars modules.tar.gz first thing when init starts. Regards, Tony
