For a while I’ve been using a Logitech Premium USB Headset 300 with Fedora Core 4 Linux on my desktop computer at home. I mainly use it for Skype, though I sometimes use it for games or movies. It didn’t require any configuration; I just plugged it in and it worked.
I unintentionally left the headset behind at a friends house 1500 miles away. I’ll get it back eventually, but in the mean time I decided to bring home the Logitech Premium USB Headset 350 which I’ve been using at work (on a Windows XP system).
I was surprised to find that the 350 does not work nearly as well with Linux and Skype. Some Linux applications work OK with it, but some of them, including Skype, just produce loud unrecognizable noise.
I experimented with this a bit, and I think this is due to the model 350 not supporting all of the sample rates that the model 300 supported.
