+ * 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.
+ *
+ * History:
+ * Version 0.01: First working version.
+ * It's required to blacklist AverMedia USB Radio
+ * in usbhid/hid-quirks.c
+ *
+ * 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
