I am trying to enable a usb0 interface in my kernel using the rndis module. This resides under the gadget driver category in menuconfig. I am unable to figure out the correct and complete set of configurations in menuconfig to enable the rndis support. Since the gadget driver config is incomplete, I am currently facing an error when I try to modprobe g_ether on my target (linux 4.19.55 armv7l):

udc-core: couldn't find an available UDC - added [g_ether] to list of pending drivers

How to fix this error so that usb0 comes up on my target

The UDC device issue was resolved by changing the mode of musb controller to dual from kernel menuconfig. After this the g_ether gets loaded successfully asn usb0 shows up on the target. Basically a UDC device like below needs to show up on the target before g-ether can be loaded.

root@:/sys/class/udc# ls

musb-hdrc.0.auto
