How do I determine if a connected USB device is a USB flash drive?
提问by Boy
how do you determine what kind of media has been attached to the system?
您如何确定系统连接了哪种介质？
I have Ubuntu, and when I inserted an SD-card, it notices that it is in fact an SD card. Same counts for USB sticks.
我有 Ubuntu，当我插入 SD 卡时，它注意到它实际上是一个 SD 卡。USB 记忆棒的计数相同。
But how can I determine on low level when a new device is inserted, what kind of type it is?
但是，当插入新设备时，如何在低级别确定它是哪种类型？
There seems to be no information to be found on this at all.
似乎根本找不到这方面的信息。
edit: just to be more complete: I said it is a Linux environment, but actually it is Android in an Embedded environment. I tagged it Linux because I am indeed trying to check from command line.
编辑：为了更完整：我说它是Linux环境，但实际上它是嵌入式环境中的Android。我将它标记为 Linux，因为我确实在尝试从命令行进行检查。
The udevadm command is not available, and lsusb -vv shows:
udevadm 命令不可用，并且 lsusb -vv 显示：
Bus 001 Device 001: ID 1d6b:0002
Bus 001 Device 002: ID 0424:2640
Bus 001 Device 003: ID 0424:4040
Bus 002 Device 001: ID 1d6b:0001
which is very little info.
这是很少的信息。

The lsusbcommand lists the USB devices registered in the system.
Try lsusb -vvfor more detailed info. You can use the -sflag to target specific device.
该lsusb命令列出系统中注册的 USB 设备。尝试lsusb -vv获取更详细的信息。您可以使用该-s标志来定位特定设备。

It may be useful to run such a command:
运行这样的命令可能很有用：
$ udevadm info -a -p $(udevadm info -q path -n /dev/sdX)
The output may looks like follows:
输出可能如下所示：

how to determine if USB device is a USB stick
如何判断USB设备是否是U盘
SCNR. USB devices usually do not advertise their shape. Think of:
SCNR。USB 设备通常不会宣传其形状。考虑到：
- stick-based CDROM devices out there?— usually in form of a mobile connections device to ship its own windows drivers
- sticks for wireless keyboard/mice/HIDs/etc, or for audio Hymans
- that fat MP3 player that blocks all the other USB ports nearby
- 基于棒的 CDROM 设备在那里？ - 通常以移动连接设备的形式提供自己的 Windows 驱动程序
- 用于无线键盘/鼠标/HID/等，或用于音频插孔
- 那个阻止附近所有其他 USB 端口的胖 MP3 播放器
