+config USB_HID_MOUSE_POLLING_INTERVAL

+	default 10
+	depends on USB_HID_MOUSE_POLLING
+	help
+	  The "USB HID Mouse Interrupt Polling Interval" is the interval, at
+	  which your USB HID mouse is to be polled at. The interval is
+	  specified in milliseconds.
+
+	  Decreasing the interval will, of course, give you a much more
+	  precise mouse.
+
+	  Generally speaking, a polling interval of 2 ms should be more than
+	  enough for most people, and is great for gaming and other things
+	  that require high precision.
+
+	  An interval lower than 10ms is not guaranteed work on your
+	  specific piece of hardware. If you want to play it safe, don't
+	  change this value.
+
+	  Now, if you indeed want to feel the joy of a precise mouse, the
+	  following mice are known to work without problems, when the interval
+	  is set to at least 2 ms:
+
+	    * Logitech's MX-family
+	    * Logitech Mouse Man Dual Optical
+	    * Logitech iFeel
+	    * Microsoft Intellimouse Explorer
+	    * Microsoft Intellimouse Optical 1.1
+
+	  If unsure, keep it at 10 ms.
