+	tristate "USB Serial Converter support"
+	depends on TTY
+	---help---
+	  Say Y here if you have a USB device that provides normal serial
+	  ports, or acts like a serial device, and you want to connect it to
+	  your USB bus.
+
+	  Please read <file:Documentation/usb/usb-serial.txt> for more
+	  information on the specifics of the different devices that are
+	  supported, and on how to use them.
+
+	  To compile this driver as a module, choose M here: the

+config USB_SERIAL_CONSOLE
+	bool "USB Serial Console device support"
+	depends on USB_SERIAL=y
+	---help---
+	  If you say Y here, it will be possible to use a USB to serial
+	  converter port as the system console (the system console is the
+	  device which receives all kernel messages and warnings and which
+	  allows logins in single user mode). This could be useful if some
+	  terminal or printer is connected to that serial port.
+
+	  Even if you say Y here, the currently visible virtual console
+	  (/dev/tty0) will still be used as the system console by default, but
+	  you can alter that using a kernel command line option such as
+	  "console=ttyUSB0". (Try "man bootparam" or see the documentation of
+	  your boot loader (lilo or loadlin) about how to pass options to the
+	  kernel at boot time.)
+
+	  If you don't have a VGA card installed and you say Y here, the
+	  kernel will automatically use the first USB to serial converter
+	  port, /dev/ttyUSB0, as system console.
