Asus N PC，运行 10.10 x86_64 Asus N 配备 4 个 USB 2.0 端口，每个端口在外壳上标有 2.0。
尝试添加两个 usb 3.0 端口，由安装在 pci expres 插槽中的通用 usb 3.0 pci express 卡提供。新卡标有 usb 3.0 并具有蓝色端口。
卡安装在未通电的笔记本电脑上，然后笔记本电脑通电并正常启动。将 USB 3.0 闪存驱动器插入 USB 3.0 端口时没有任何反应。

trying to post dmesg exceeded the stackexchange posting limit of 30K... but nothing there is usb 3.0
答案1
看起来你的内核没有 USB 3.0 主控制器驱动程序。
由于您正在运行定制的内核，因此您需要将其添加到当前内核构建配置中。
启用此驱动程序的配置参数是CONFIG_USB_XHCI_HCD。您可以make menuconfig通过启用“xHCI HCD（USB 3.0）支持”选项来启用此功能（在对话框中）。
该选项可在以下位置找到：设备驱动程序 -> USB 支持 -> 主机端 USB 支持 -> xHCI HCD（USB 3.0）支持。
