The D-Link USB FM radio driver uses the Video4Linux interface, similar to the webcams discussed above.
If the appropriate device node entries do not exist, you should create them:
mknod /dev/video0 c 81 0 mknod /dev/video1 c 81 1 mknod /dev/video2 c 81 2 mknod /dev/video3 c 81 3 ln -s /dev/video0 /dev/video |
After plugging the radio in, all you should you need to do is to start up an appropriate application - I normally use kradio and KTuner from KDE, although any Video4Linux radio application should work successfully.
