找出工作 PCI(e) 设备的 PCI(e) ID，在本例中为 USB 控制器

找出工作 PCI(e) 设备的 PCI(e) ID，在本例中为 USB 控制器

我将一张 mPCIe 卡（一个 USB 控制器）插入到我的计算机的一个 mPCIe 插槽中。连接的 USB 设备显示为lsusb并且一切正常。

现在我正在运行 KVM/qemu，我不仅希望将单个 USB 设备传递，还希望将 USB 控制器作为 PCIe 设备传递到虚拟机 - 正如我已经对板载 NIC（也是 PCIe）所做的那样。

所以我认为 USB 控制器在调用时会宣布自己是 PCI 连接设备lspci- 但事实并非如此：

该计算机是PC引擎APU2嵌入式计算机，基于AMD（https://www.pcengines.ch/apu2.htm) - 运行 Debian Linux。

lsusb显示已连接的 USB 设备正在连接到相关 USB 控制器。

问题：如何找出我的 USB 控制器连接到哪个 PCI(e) ID/设备，以便知道要传递哪个 PCI(e) ID/设备，以便它作为本机 PCI(e) 设备在我的虚拟机中弹出？

我可能通过 USB 总线 ID 推测lsusb出什么 - 但这是我所得到的。
