# hpen.4

`hpen` — 兼容 MS Windows 的 HID 数位板驱动

## 名称

`hpen`

## 概要

`要将此驱动编译进内核，请在你的内核配置文件中加入以下行：`

> device hpen device hid device hidbus device hidmap device evdev

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

```sh
hpen_load="YES"
```

## 描述

`hpen` 驱动为连接到 HID 传输后端的通用兼容 MS Windows 的 HID 数位板和数字化仪提供支持。参见 [iichid(4)](/man/man4/iichid.4.md) 或 [usbhid(4)](https://github.com/FreeBSD-Ask/freebsd-man-sc/blob/main/man4/usbhid.4.md)。

`/dev/input/event*` 设备将数位板呈现为 `evdev` 类型设备。

## SYSCTL 变量

以下变量同时作为 [sysctl(8)](/man/man8/sysctl.8.md) 变量和 [loader(8)](/man/man8/loader.8.md) 可调参数可用：

**`dev.hpen.X.debug`** 调试输出级别，0 表示禁用调试，值越大调试消息越详细。默认为 0。

其默认值通过 [loader(8)](/man/man8/loader.8.md) 可调参数设置：

**`hw.hid.hpen.debug`**

## 文件

**`/dev/input/event*`** 输入事件设备节点。

## 参见

[iichid(4)](/man/man4/iichid.4.md), [usbhid(4)](https://github.com/FreeBSD-Ask/freebsd-man-sc/blob/main/man4/usbhid.4.md), xorg.conf(5) (`ports/x11/xorg`)

## 缺陷

`hpen` 无法像 [sysmouse(4)](/man/man4/sysmouse.4.md) 那样工作。

不支持数位笔电池电量报告。

## 历史

`hpen` 驱动最早出现在 FreeBSD 13.0 中。

# 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/hpen.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.
