        ---help---
+         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.
