“lsusb”和“lsusb -t”显示不同的结果

我的 ESXi 7.0 主机上的 USB 设备出现问题,我打开控制台并开始使用 lsusb:

[root@localhost:~] lsusb

Bus 003 Device 001: ID 0e0f:8002 VMware, Inc. Root Hub
Bus 003 Device 002: ID 8087:8002 Intel Corp. 8 channel internal hub

此处,只有一个“16c0:05df”设备,没有“0bda:5411”USB 集线器。然后我尝试:

[root@localhost:~] lsusb -t
Bus#  1
`-Dev#   1 Vendor 0x0e0f Product 0x8003
  |-Dev#   2 Vendor 0x16c0 Product 0x05df

Bus#  3
`-Dev#   1 Vendor 0x0e0f Product 0x8002
  `-Dev#   2 Vendor 0x8087 Product 0x8002

这次,我看到“0bda:5411”集线器和集线器下的第二个“16c0:05df”(这是实际的硬件配置)。在执行命令时,第二个“16c0:05df”根本不工作(好像没有检测到),但“0403:6001”(也连接到集线器的串行到 USB)工作正常。

知道为什么有两种不同的输出,以及它来自哪里吗? (在 ESXi 中,我无权访问 sysfs)
