USB 3.0 SuperSpeed SATA 桥仅检测为高速设备

2024-6-20 • tag-icon

我有一些 USB/SATA 桥接设备 (Scythe Kama Connect)，声称（在其彩色盒子上）支持 USB 3.0 SuperSpeed。

但是，当我将其连接到 AlderLake Linux 系统时，它仅被检测为 HyperSpeed 设备：

因此，在访问连接的硬盘时，我只看到 23 MiB/s 左右的 IO 吞吐量。

FWIW，该系统位于 Fedora 37 (6.2.15-200.fc37.x86_64) 上，并且该设备直接连接到笔记本电脑机箱 USB 端口。
