# urio.4

`urio` — Rio MP3 播放器的 USB 驱动

## 名称

`urio`

## 概要

要将此驱动编译进内核，请将以下行加入你的内核配置文件：

> device urio

或者，要在引导时以模块方式加载该驱动，请将以下行加入 loader.conf(5)：

```sh
urio_load="YES"
```

## 描述

`urio` 驱动为连接到 USB 端口的 Diamond MultiMedia Rio MP3 播放器提供支持。`urio` 设备必须在内核中配置，同时还需要 *usb* 以及 *uhci* 或 *ohci* 控制器之一。

随后，Rio 用户态应用程序可以使用 **/dev/urio0** 设备。

## 硬件

以下设备受 `urio` 驱动支持：

* Diamond MultiMedia Rio 500
* Diamond MultiMedia Rio 600
* Diamond MultiMedia Rio 800

## 文件

**/dev/urio0** 阻塞型设备节点

## 实例

在内核配置文件中加入以下行可将 `urio` 驱动添加到内核：

```sh
device urio
```

使用 rio\_add\_song(1) 工具（参见 Sx SEE ALSO 段）通过 USB 连接将歌曲下载到 Rio：

```sh
rio_add_song /usr/local/MP3/TracyChapman/02-Fast-Car.mp3
```

## 参见

[ohci(4)](/man/man4/ohci.4.md), [uhci(4)](https://github.com/FreeBSD-Ask/freebsd-man-sc/blob/main/man4/uhci.4.md), [usb(4)](https://github.com/FreeBSD-Ask/freebsd-man-sc/blob/main/man4/usb.4.md)

> "The Rio 500 SourceForge Project Web Page".

SourceForge 上的 Rio500 工具是用于下载、格式化或重命名播放器上歌曲的实际用户态工具。编译这些工具时，以下预构建配置命令可确保 `rio_usb.h` 在包含路径中可用，并且所使用的设备为 **/dev/urio0**：

```sh
CFLAGS="-I/usr/include/dev/usb" ./configure \
    --with-devicepath='/dev' --with-deviceentry='urio0'
```

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://book.bsdcn.org/man/man4/urio.4.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
