将 hidraw 设备从鼠标更改为操纵杆

将 hidraw 设备从鼠标更改为操纵杆

我有一个无线 PS3 控制器适配器,已插入我的 Ubuntu 14.04 盒子。它有两种模式:XInput 和 DInput,据我所知,它只是通过 USB 传递两个不同的供应商/产品 ID(XInput 有一个 Microsoft XBOX id,另一个是通用的)。 XInput 模式工作正常(加载 xpad 驱动程序),但在 DInput 模式下,内核将设备识别为鼠标,而不是操纵杆。

相关问题:

我需要更改什么才能使其识别为操纵杆?

usbhid 驱动程序如何为字符设备分配次要编号?

更新

在我寻求知识的过程中,我发现了一个列出了 usbhid 驱动程序的主要/次要编号的网站。如下所示,我的设备是 13,32,它是由驱动程序为 mouse0 保留的。看来我需要欺骗(?)驱动程序为其分配不同的次要编号? ……还是我走错了路? (不可否认,我对 Windows 驱动程序开发比 Linux 更熟悉)

答案1

HID 系统检查是否有与供应商和产品 ID 匹配的专用驱动程序,如果没有,则将其视为通用 HID 设备:设备发送的描述符用于确定它是什么。

在你的情况下有专门的hid驱动程序,但看起来没有加载。您可以尝试modprobe hid-dr,但您可能没有安装它。在Ubuntu上,它在linux-image-extra包装中
