`ubsa` — Belkin 串行适配器的 USB 支持

## 名称

`ubsa`

## 概要

`若要将此驱动编译进内核，请在内核配置文件中加入以下行：`

> device usb device ucom device ubsa

`或者，要在引导时以模块形式加载驱动，请在 loader.conf(5) 中加入以下行：`

```sh
ubsa_load="YES"
```

## 描述

`ubsa` 驱动提供对 Belkin 及其他厂商的多种串行适配器所用 USB 转 RS232 桥接芯片的支持。

该设备通过 [ucom(4)](/man/man4/ucom.4.md) 驱动访问，使其行为类似 [tty(4)](/man/man4/tty.4.md)。

## 硬件

`ubsa` 驱动支持以下适配器：

* AnyData ADU-500A EV-DO 调制解调器
* AnyData ADU-E100A（不支持 EV-DO 模式）
* Belkin F5U103
* Belkin F5U120
* e-Tek Labs Kwik232
* GoHubs GoCOM232
* Peracom 单端口串行适配器

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/ubsa.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.
