lsusb -v 提供 USB 设备的详细响应。

例子：

现在我只想查看设备部分bInterfaceProtocol，或者我想列出所有 USB 设备的内容。有人能告诉我这个的具体格式吗？Interface DescriptorBus 003 Device 003bInterfaceProtocol

您无法仅使用以下方法完成此操作lsusb。您可以：

  1. 使用-s或-d选项来制作lsusb仅显示特定设备的输出：

    -s [[bus]:][devnum]
      Show only devices in specified bus and/or devnum.  Both ID's are
      given in decimal and may be omitted.

-d [vendor]:[product]
      Show  only  devices  with  the  specified vendor and product ID.
      Both ID's are given in hexadecimal.

  2. 并用来grep过滤掉字段。

例如：

$ lsusb

Bus 003 Device 003: ID 0e0f:0002 VMware, Inc. Virtual USB Hub

$ lsusb -s 003:003
Bus 003 Device 003: ID 0e0f:0002 VMware, Inc. Virtual USB Hub
$ lsusb -s 003:003 -v | grep bInterfaceProtocol
  bInterfaceProtocol      0 Full speed (or root) hub
# lsusb -v | grep -e bInterfaceProtocol -e Bus
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
      bInterfaceProtocol      0 Full speed (or root) hub
