我有一台 Iomega Prestige 便携式外置硬盘 1TB USB 3.0。
它可以作为 USB 3.0 驱动器在 Windows 7 上正常运行。
在 ubuntu natty 64bit, 2.6.38-8-generic 上检测不到它。
fdisk -l 根本看不到它：

lsusb 可以看到：

然后 dmesg | grep -i xhci （我可能拔下了驱动器并在启动后重新插入）：

我认为可能是固件与 Linux 不兼容或者其他原因，但是在启动 partedmagic 的实时映像（2.6.38.4-pmagic）时，驱动器被正确检测到，我可以安装它并获得 USB 3.0 速度（至少它们是我将相同驱动器插入 USB 2 端口时速度的两倍）。
partedmagic 中的 dmesg 确实说了有关没有 SuperSpeed 端点的信息，这是我在之前的 ubuntu dmesg 中看到的错误：

好吧，我不知道出了什么问题，到目前为止，我在谷歌和论坛上也没有找到多少线索。许多帖子都没有得到答复，只有遇到类似错误消息和问题的人。
希望这里有人可以帮助我或者给我指明正确的方向？！
