  * When work was looked pretty good, i discover this:
  * http://av-usbradio.sourceforge.net/index.php
  * http://sourceforge.net/projects/av-usbradio/
  * Latest release of theirs project was in 2005.
  * Probably, this driver could be improved trough using their
  * achievements (specifications given).
- * So, we have smth to begin with.
+ * Also, Faidon Liambotis <paravoid@debian.org> wrote nice driver for this radio
+ * in 2007. He allowed to use his driver to improve current mr800 radio driver.

  *
- * History:
  * Version 0.01:	First working version.
  * 			It's required to blacklist AverMedia USB Radio
  * 			in usbhid/hid-quirks.c
+ * Version 0.10:	A lot of cleanups and fixes: unpluging the device,
+ * 			few mutex locks were added, codinstyle issues, etc.
+ * 			Added stereo support. Thanks to
+ * 			Douglas Schilling Landgraf <dougsland@gmail.com> and
+ * 			David Ellingsworth <david@identd.dyndns.org>
+ * 			for discussion, help and support.
  *
  * Many things to do:
  * 	- Correct power managment of device (suspend & resume)
- * 	- Make x86 independance (little-endian and big-endian stuff)
  * 	- Add code for scanning and smooth tuning
- * 	- Checked and add stereo&mono stuff
  * 	- Add code for sensitivity value
  * 	- Correct mistakes
  * 	- In Japan another FREQ_MIN and FREQ_MAX
