+ This is a driver for USB devices with the Silicon Labs SI470x
+ chip. Currently these devices are known to work:
+ - 10c4:818a: Silicon Labs USB FM Radio Reference Design
+ - 06e1:a155: ADS/Tech FM Radio Receiver (formerly Instant FM Music)
+ - 1b80:d700: KWorld USB FM Radio SnapMusic Mobile 700 (FM700)
+
+ Sound is provided by the ALSA USB Audio/MIDI driver. Therefore
+ if you don't want to use the device solely for RDS receiving,
+ it is recommended to also select SND_USB_AUDIO.
+
+ Please have a look at the documentation, especially on how
+ to redirect the audio stream from the radio to your sound device:
+ Documentation/video4linux/si470x.txt
+
Say Y here if you want to connect this type of radio to your
computer's USB port.
