我最近买了一个蓝色 Snowball iCE 麦克风. 看起来是这样的人和这个人在早期版本的 Ubuntu 上成功使用了它。当我插入这个麦克风时，它根本无法被识别。我将其插入我的 Windows 7 盒子，它工作得很好。下面是运行 dmesg 和 lsbusb -v 的输出。我喜欢麦克风的质量，有人能帮忙吗！
当我运行 dmesg 时，我看到以下消息：
[ 9398.403809] usb 3-1: new full-speed USB device number 24 using xhci_hcd
[ 9408.410102] usb 3-1: New USB device found, idVendor=0d8c, idProduct=0005
[ 9408.410108] usb 3-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[ 9408.410111] usb 3-1: Product: Blue Snowball
[ 9408.410502] usb 3-1: can't set config #1, error -32
我一直在谷歌上搜索，想弄清楚这个错误可能意味着什么，但没有成功。
当我运行 lsbusb -v 时，我得到以下与麦克风相关的信息：

这是来自 syslog 的输出：

答案1
蓝色雪球冰不起作用开箱即用的 Ubuntu 14.04。如果您正在为您的 Ubuntu 14.04 盒子寻找麦克风，请不要购买这个。我买了 Audio-Technica 的 ATR2100，效果很好。
如果您想要蓝色雪球，我建议您购买原始版本（而不是 iCE）。我还没有尝试过，但在与一些人交谈后，原始版本似乎对他们有用。
