USB设备无法分配到不同总线及雷电端口PCI直通失败的问题求助

我目前用的是i9-13900K处理器搭配华硕Z790主板，遇到了两个头疼的USB相关问题，想请教各位大佬帮忙解决：

1. USB设备统一归到Bus 1的问题
   不管我把设备插在主板哪个USB接口上，用lsusb查看时所有设备全被分配到了Bus 1——哪怕是连接到三个独立PCI总线的雷电3（USB-C）接口上的集线器，其下的所有设备也都归到Bus 1。感觉是Linux的总线分配机制导致的，我想把不同接口的设备分到不同总线，这样才能单独把某条总线的PCI设备直通给虚拟机。

2. 雷电端口PCI直通失败的问题
   我尝试把雷电端口对应的PCI地址直通给虚拟机，但虚拟机完全识别不到这个设备，不知道哪里出了问题。
