This same keyboard worked fine all the time in Ubuntu 12.04 (though on a different laptop). I now have 13.10 installed on a new laptop and I'm getting a few annoying problems with my external USB keyboard, specifically the multimedia functions.
Problem 1:
The "calculator" or "www/internet" buttons do nothing. If I go to the Shortcuts control panel and try to bind "Launch Calculator" to a new accelerator, pressing the Calculator button does not register at all. It's just not detecting that I pressed it.
Problem 2:
The volume up and volume down keys work a little bit -- however once I tap them once or twice, it infinitely keeps pressing the key forever, forcing the volume either to maximum or silent. I have to unplug the USB cable and plug it back in to stop it.
I imagine this has something to do with evdev but I have no idea how to fix it. I have tried troubleshooting using the steps at https://wiki.ubuntu.com/Hotkeys/Troubleshooting but when I run sudo evtest
I get nothing when I press the multimedia keys (regular keys give feedback).
Note: my laptop has a built-in keyboard with volume controls, and they work normally as expected.

Update July 28, 2013:
Problem still occurs in Ubuntu 14.04, though the WWW, Mail, and Calculator media keys seem to work now. The volume up/down problem persists.
