+  Description:	metro-usb.c is the drivers main source file. The driver is a USB to Serial converter.
+		The driver takes USB data and sends it to a virtual ttyUSB# serial port.
+		The driver interfaces with the usbserial.ko driver supplied by Linux.
+
+		NOTES:
+		To install the driver:
+		1. Install the usbserial.ko module supplied by Linux with: # insmod usbserial.ko
+		2. Install the metro-usb.ko module with: # insmod metro-usb.ko vender=0x#### product=0x#### debug=1
+		   The vendor, product and debug parameters are optional.
+
+		Some of this code is credited to Linux USB open source files that are distributed with Linux.

+  1/30/2007		Philip Nicastro		Initial release. (v1.0.0.0)
+  2/27/2007		Philip Nicastro		Changed the metrousb_read_int_callback function to use a loop with the tty_insert_flip_char function to copy each byte to the tty layer. Removed the tty_buffer_request_room and the tty_insert_flip_string function calls. These calls were not supported on Fedora.
+  2/27/2007		Philip Nicastro		Released. (v1.1.0.0)
+  10/07/2011		Aleksey Babahin		Update for new kernel (tested on 2.6.38)
+						Add unidirection mode support
