4 * only deals with initialization and frequency setting, the

25 * Big thanks to authors of dsbr100.c and radio-si470x.c
26 *
27 * When work was looked pretty good, i discover this:
28 * http://av-usbradio.sourceforge.net/index.php
29 * http://sourceforge.net/projects/av-usbradio/
30 * Latest release of theirs project was in 2005.
31 * Probably, this driver could be improved trough using their
32 * achievements (specifications given).
33 * So, we have smth to begin with.
34 *
35 * History:
36 * Version 0.01: First working version.
37 * It's required to blacklist AverMedia USB Radio
38 * in usbhid/hid-quirks.c
39 *
40 * Many things to do:
41 * - Correct power managment of device (suspend & resume)
42 * - Make x86 independance (little-endian and big-endian stuff)
43 * - Add code for scanning and smooth tuning
44 * - Checked and add stereo&mono stuff
45 * - Add code for sensitivity value
46 * - Correct mistakes
47 * - In Japan another FREQ_MIN and FREQ_MAX
