*
* See Documentation/usb/usb-serial.txt for more information on using this driver
*
- * 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.
- *
- * 2001_Sep_19 gkh
- * Added break support.
- *
- * 2001_Aug_30 gkh
- * fixed oops in write_bulk_callback.
- *
- * 2001_Aug_28 gkh
- * reworked buffer logic to be like other usb-serial drivers. Hopefully
- * removing some reported problems.
- *
- * 2001_Jun_06 gkh
- * finished porting to 2.4 format.
