You must have gotten hold of an old version of usb.c.  The version I have
and the version available on the web site:

	http://www.linux-usb.org/gadget/usb.c

both contain this code in autoconfig():

	/* OMAP 1610 and newer devices, full speed only, fifo mode 0 or 3 */
	} else if (stat (DEVNAME = "omap_udc", &statb) == 0) {
		HIGHSPEED = 0;
		device_desc.bcdDevice = __constant_cpu_to_le16 (0x0106),

		fs_source_desc.bEndpointAddress = USB_DIR_IN | 1;
		EP_IN_NAME = "ep1in-bulk";
		fs_sink_desc.bEndpointAddress = USB_DIR_OUT | 2;
		EP_OUT_NAME = "ep2out-bulk";

		source_sink_intf.bNumEndpoints = 3;
		fs_status_desc.bEndpointAddress = USB_DIR_IN | 3;
		EP_STATUS_NAME = "ep3in-int";
