* 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.
+ * http://kerneltrap.org/mailarchive/linux-usb-devel/2007/10/11/342492
*
- * 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.
+ * Version 0.11: Converted to v4l2_device.
*
* 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
