This should be a complete list:

definitions:
        static const struct usb_device_id smsusb_id_table[] __devinitconst = {
        static const __devinitdata struct usb_device_id device_table[] = {
        static const struct usb_device_id device_table[] __devinitconst = {
        static struct usb_device_id p54u_table[] __devinitdata = {
        static struct usb_device_id rtl8187_table[] __devinitdata = {
        static struct usb_device_id vt6656_table[] __devinitdata = {
        static const struct usb_device_id wb35_table[] __devinitconst = {
        static const struct usb_device_id id_table[] __devinitconst = {
