Windows 7 上 USB-3 集线器支持需要驱动程序吗?

Windows 7 上 USB-3 集线器支持需要驱动程序吗?

我刚刚购买了一个 Koutech HU-430 4 端口 USB 超高速集线器。

当使用附带的 USB3 A/B 电缆插入 USB-3 端口时,Windows 会将其检测为“瑞萨电子 USB 2.0 集线器”。

在此处输入图片描述

这是否意味着设备有故障,或者我需要安装另一个驱动程序?

VID为0x2109,PID为0x3431,如下所示:

升级到最新的 Renesas 驱动程序 (2.1.25.0) 解决了该问题。

我的主板制造商没有费心将新驱动程序放在他们的网站上,但英特尔有这里

如图所示,集线器显示为两个设备(具有正确的驱动程序),以下是第二个设备的描述符(不幸的是,我没有注意到在驱动程序升级之前是否列出了它):
