USB 仅在恢复模式下启动时有效

USB 仅在恢复模式下启动时有效

我在 HP Pavilion Windows 平板电脑上安装了 Ubuntu 14.04 LTS 64 位,该平板电脑配有 Intel® Core™ i3-4030U CPU @ 1.90GHz × 4。启动 Ubuntu 后,我的 USB 鼠标无法使用。启动过程中激光会亮起,但登录屏幕出现时,激光会熄灭。我认为这显然是 USB 设备的问题,因为当我插入 USB 棒时,驱动器没有出现,并且我的 /dev/ 文件夹中只有 sda。通常我必须重新启动几次才能使 USB 设备正常工作。什么可能导致此问题?

lsusbUSB 端口不工作时的输出如下:

stefan@stefan-HP-Pavilion-13-x360-PC:~$ lsusb
Bus 001 Device 002: ID 8087:8000 Intel Corp. 
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

我重新启动了系统,现在 USB 可以正常工作了。lsusb输出如下:

stefan@stefan-HP-Pavilion-13-x360-PC:~$ lsusb

在总线 003 设备 002 上,空白行用于 USB 存储设备。在总线 002 设备 002 上,我们有光电鼠标。

编辑:我发现每次我启动系统时,USB 都能正常工作,方法是先在 GRUB 中启动恢复模式,然后在菜单中选择“恢复”。但是当我定期启动系统时,USB 从来不工作。

以下是正常启动后 USB 正常工作时 dmesg | grep usb 的输出:

编辑(2015年8月25日):我发现了一些有趣的现象。每当我启动 Windows 8(USB 从未出现任何问题)时,然后重新启动并从 GRUB 菜单中选择 Ubuntu,它就会突然正常工作。Windows 下正常运行的 USB 如何在重新启动到 Ubuntu 后正常工作?

答案1

好的,通过切换到最新的 Ubuntu 版本(15.10),问题得到了解决威利)。安装 Wily 时,我还从笔记本电脑中删除了 Windows,因此现在这是一个单启动系统(如果这与问题有任何关系的话)。到目前为止,我在 Ubuntu Wily 中没有发现任何问题。
