**注意**：该面板之前包含共享蓝牙设置，Parallels Desktop for Mac 26 已弃用该设置。连接到 Mac 的蓝牙设备(如键盘、鼠标或游戏控制器)将继续在虚拟机中正常工作。

要将蓝牙设备直接连接到虚拟机，请考虑使用 USB 蓝牙加密狗。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.parallels.com/landing/pdfm-ug/v27-zh-cn/parallels-desktop-for-mac-27-yong-hu-zhi-nan/parallels-desktop-pian-hao-she-zhi-he-xu-ni-ji-she-zhi/xu-ni-ji-she-zhi/ying-jian-she-zhi/usb-he-lan-ya-she-zhi.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
