Thank you very much for that.

For anyone on Ubuntu 11.04 (not sure about other versions), libhid-dev seems to be missing from the default repos.

I downloaded it from http://forums.linuxmint.com/viewtopic.php?f=109&t=66957&start=0. See the dpkgs in the .tar.gz attached. I also had to install libusb-dev to install those packages.

To get my applications to use the RocketFM device, I also installed Pulse Audio Device Chooser as per this thread http://ubuntuforums.org/showthread.php?t=965860. Works well.

Again, thanks.
