# zyd.4

`zyd` — ZyDAS ZD1211/ZD1211B USB IEEE 802.11b/g 无线网络驱动

## 名称

`zyd`

## 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 ehci device uhci device ohci device usb device zyd device wlan device wlan\_amrr

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
if_zyd_load="YES"
```

## 描述

`zyd` 驱动为基于 ZyDAS ZD1211 和 ZD1211B USB 芯片的无线网络适配器提供支持。

`zyd` 支持 `station` 和 `monitor` 模式操作。任何时候只能配置一个虚拟接口。有关配置此设备的更多信息，请参见 [ifconfig(8)](/man/man8/ifconfig.8.md)。

## 实例

以下示例将 zyd0 配置为使用 WEP 密钥“0x1deadbeef1”、信道 11 加入任意 BSS 网络：

```sh
ifconfig wlan create wlandev zyd0 channel 11 e
    wepmode on wepkey 0x1deadbeef1 weptxkey 1 e
    inet 192.0.2.20/24
```

加入现有的 BSS 网络 `my_net`：

```sh
ifconfig wlan create wlandev zyd0 192.0.2.20/24 e
    ssid my_net
```

## 诊断

* zyd%d: could not load firmware (error=%d) 尝试将固件上传到板载微控制器单元时发生错误。
* zyd%d: could not send command (error=%s) 向固件发送命令的尝试失败。
* zyd%d: sorry, radio %s is not supported yet 驱动尚未实现对指定射频芯片的支持。设备不会附加。
* zyd%d: device version mismatch: 0x%x (only >= 43.30 supported) 此驱动不支持 ZD1211 芯片组的早期修订版本。设备不会附加。
* zyd%d: device timeout 分派到硬件进行传输的帧未及时完成。驱动将重置硬件。这不应发生。

## 作者

原始 `zyd` 驱动由 Florian Stoehr <ich@florian-stoehr.de>、Damien Bergamini <damien@openbsd.org> 和 Jonathan Gray <jsg@openbsd.org> 编写。

## 注意事项

`zyd` 驱动不支持硬件中可用的大量功能。要正确支持 IBSS 和电源管理功能，还需要更多工作。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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/zyd.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.
