我买了这台联想笔记本电脑https://www.lenovo.com/gb/en/p/laptops/legion-laptops/legion-slim-series-laptops/lenovo-legion-slim-7-gen-8-(16-inch-amd)/ len101g0029#tech_specs应该支持USB 4.0。然而lsusb -t返回这个输出：
$ lsusb -t

我看不到任何超过10000M的速率。在我的另一台配备 Thunderbolt 4 的笔记本电脑上，我可以看到 20000M。我用的是PoOS
$ uname -a
Linux pop-os 6.5.4-76060504-generic
Linux 内核 6.5.4 应该检测到 USB4，不是吗？
我错过了什么？联想是否在我的笔记本电脑上安装了错误的硬件端口？我应该退回这台笔记本电脑吗？
