Please don't top post. So, you build g_ether static, omap_udc(?) as a module, and the host works? Does the gadget actually work? I suspect not, I can't see how it would since usb_gadget_register_driver() etc don't exist until you load the gadget module. I don't have much experience with the usb gadget stuff. But perhaps you could be a bit clearer about which combinations actually work, and whether both host AND gadget work in each case?
