The USB Headset Buttons software allows you to use the volume up and down buttons on your Logitech USB 30 headset.
To use this application, you'll need to meet the following requirements: Linux 2.6 and ALSA libasound2 header files. You can compile it with the Makefile and ensure that you have the libasound2 header files installed. For Debian, you can easily install this with "apt-get install libasound2-dev."
Once this is installed, you can run the application and specify which devices to use by entering specific command-line options. For example, you can enter the '-e' option for the input event device, which is typically '/dev/input/event?' To find the exact event node that corresponds to your headset's input, you can navigate to /sys/class/input/ and check the input? directories.
In addition, you can enter the '-s' option for ALSA hardware and '-n' for ALSA subdevice to use. These options allow you to adjust settings like speaker playback volume.
Some notable updates for this release include a note in the README that highlights the need for CONFIG_INPUT_EVDEV to be enabled in the kernel. Additionally, a new '-a' switch has been added to the software, and you can now set the number of steps that are changed on a keypress. Overall, I found USB Headset Buttons to be a practical solution for managing the volume buttons on my headset during VoIP calls.
