- * See Documentation/usb/usb-serial.txt for more information on using this driver
-- * 2003_Apr_24 gkh
-- * Added line error reporting support. Hopefully it is correct...

-+ * 2005_Mar_05 grsch
-+ * ported 2.6.8 pl2303.c to 2.4.20 format
-+ * (HX model works fine now, ID table should be brought up to date)
-+ * Gregor Schaffrath <gschaff@ran-dom.org>
-+ *
-+ * 2002_Mar_26 gkh
-+ * allowed driver to work properly if there is no tty assigned to a port
-+ * (this happens for serial console devices.)
- *
- * 2001_Oct_06 gkh
- * Added RTS and DTR line control. Thanks to joe@bndlg.de for parts of it.
