I am trying to get 3.14 kernel to work, first. There, usb gadget works
when compiled into kernel. But with modules, I get

# root@(none):/tmp# insmod libcomposite.ko                                      
# root@(none):/tmp# insmod u_ether.ko                                           
# root@(none):/tmp# insmod usb_f_rndis.ko                                       
# root@(none):/tmp# insmod g_ether.ko                                           

[  169.061218] udc musb-hdrc.0.auto: registering UDC driver [g_ether]
[  169.078918] g_ether musb-hdrc.0.auto: failed to start g_ether: -2

-2 is ENOENT...
