+	help
+	  This is another driver for the Atheros "otus" 802.11n USB devices.
+
+	  This driver provides more features than the original,
+	  but it needs a special firmware (carl9170-1.fw) to do that.
+
+	  The firmware can be downloaded from our wiki here:
+	  <http://wireless.kernel.org/en/users/Drivers/carl9170>
+
+	  If you choose to build a module, it'll be called carl9170.

+	  Provides a hardware random number generator to the kernel.
+
+	  SECURITY WARNING: It's relatively easy to eavesdrop all
+	  generated random numbers from the transport stream with
+	  usbmon [software] or special usb sniffer hardware.
+
+	  Say N, unless your setup[i.e.: embedded system] has no
+	  other rng source and you can afford to take the risk.
