获取有关我的 USB 设备的信息

曾经有很多关于 USB 设备的信息，来自 /proc/bus/usb/devices。

然后它不再自动挂载，所以你必须自己挂载它（它被称为 usbdevfs，或类似的东西）

现在，在 11.04 中，甚至连这个都行不通了。我现在如何才能获取有关我的设备的一些信息？

答案1

lsusb显示如下：

Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 004: ID 0bda:0138 Realtek Semiconductor Corp. 
Bus 001 Device 003: ID 064e:c218 Suyin Corp.  
Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

你还需要知道什么？

如果你需要更多，请usbview访问源码：USBView 是一个 GTK 程序，可显示插入 Linux 机器上的 USB 总线的设备的拓扑结构。它还显示每个设备的信息。这对于确定设备是否正常工作很有用。

在此处输入图片描述

顺便说一下，我还没试过 11.04 版的 usbview

答案2

/proc正在被弃用，/sys/bus/usb/devices这就是你要找的。查询 USB 设备的程序是lsusb。

答案3

以下是一些用于收集已连接设备 USB 信息的好工具，

usb-devices：

这是默认包 usbutils于 18.04 LTS。样本输出：

T:  Bus=01 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#=  1 Spd=480 MxCh= 6
D:  Ver= 2.00 Cls=09(hub  ) Sub=00 Prot=01 MxPS=64 #Cfgs=  1

I:  If#= 0 Alt= 0 #EPs= 2 Cls=08(stor.) Sub=06 Prot=50 Driver=usb-storage

。

udevadm monitor

udevadm是默认包 udev在 18.04 LTS 上。

执行此命令前您连接您的 USB 设备。

请注意，下面的样本输出告诉我们 USB 闪存驱动器加载为哪个块设备：

udevadm monitor
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent
