+如果设备试图从 USB 启动（可能是因为您将其设为了默认，或按下了 Ctrl+U）失败，那么您将听到一次相当响亮的“哔”声。
 
+<!-- 
 Note that ChromeOS bootloader USB enumeration during boot has been observed to be slow. If you're
 having trouble booting from USB, it may be helpful to remove other USB devices
 until the device is through the bootloader and also avoid using a USB hub.
+ -->
+注意，已经观察到启动过程中 ChromeOS 引导加载程序 USB 枚举速度很慢。如果您在从 USB 启动时遇到问题，那么在设备通过引导加载程序前，移除其他 USB 设备可能会有所帮助；另外，也请避免使用 USB 集线器。

+<!-- 
 By default the ChromeOS bootloader has a long timeout to allow you to press
 buttons. To shortcut this you can press Ctrl+D or Ctrl+U when on the grey screen
 that warns that the OS will not be verified. Ctrl+D will cause the device to
 skip the timeout and boot from its default source. Ctrl+U will skip the timeout
 and boot the device from USB.
+ -->
+默认情况下，ChromeOS 引导加载程序的超时等待时间很长，以便您能够按下按键。要跳过此过程，您可以在警告 OS 无法验证的灰色画面中按下 Ctrl+D 或 Ctrl+U。Ctrl+D 将使设备跳过超时等待，并从其默认源启动。Ctrl+U将跳过超时等待，并从 USB 启动设备。
