Re: [PATCH 6/7] HID: N-trig MTM Driver fix And cleanup patch 6

  static const struct hid_device_id ntrig_devices[] = {
  	{ HID_USB_DEVICE(USB_VENDOR_ID_NTRIG, USB_DEVICE_ID_NTRIG_TOUCH_SCREEN),
-		.driver_data = NTRIG_DUPLICATE_USAGES },
+		.driver_data = NTRIG_USB_DEVICE_ID },

The vendor and device id are in the first field "HID_USB_DEVICE", driver data is for flags, not id. Its merely a coincidence that they are the same in this case.

The duplicate usages tells hid to let you have more than one "x" and "y" axis. Otherwise each finger gets a new set (the second finger gets "z" and "rx" and so on).

  static int __init ntrig_init(void)
  {
+	info("N-trig Driver Version 1.6\n");

Perhaps you mean:
MODULE_VERSION("1.06");
