    Lucid not detecting USB mic

    Well I have this really shweet Samson C01U usb studio condenser mic. When it is plugged in before I boot my machine, everything works like a charm, and I can sound like a rockstar recording my stuffs in UbuntuStudio 10.04 x64.

    But when I'm not being a rockstar, I'm using my normal Lucid distro to go about my everyday tasks. So when I decide to call someone on skype, I plug the mic in, and nothing happens. The sound config window does not show the device? I do not want to reboot every time to use the mic (and that's all that works), and I do not want to leave it standing on my desk either.

    Any ideas? Maybe I should restart Pulse or something? Help would be appreciated!

    So when u restart your computer with the mic plugged in, it works after reboot?

    Is it a usb or rca connection?

    Is it an onboard soundcard?

    Are you plugging it into the soundcard directly or the front panel?

    Run this command when plugging in the mic

    Code:
    sudo tail -f /var/log/messages
    And post the output

    Like I said, it is a usb mic. So it has nothing to do with the soundard on my machine. All the sound conversion takes place in the mic and the digital signal is sent to the PC. Ubuntu then picks it up as another sound card. It works completely seperately from the onboard sound. And yeah the mic works when I plug in before a boot. If I plug it in after I reboot it doesnt work. Here is the output:
