How can I identify USB Storage "volume name" under Linux?

I'm trying to write a script that make a list of connected USBs list like this:

  • MyFlash - ADATA
  • BootUSB - ADATA
  • MyBackup - SAN DISK

But I don't know how to identify the connected USB device is a storage one, and the volume name of it.

C/C++, Python, or Node.js help are welcome, and only under Linux OS.

I'm looking to mount and remount using code, but I think It will be easy to use Linux commands for this.

I'm pretty sure that external devices like that show up under the "sda, sdb, etc" list. - durbnpoisn
I know @durbnpoisn, but I'm looking how Linux mount it with the its name, there is a place where Linux gets USb storage information. Till now, using usb-devices command line, I can know that the connected device is a usb-storage. But the volume name, I'm still searching about it. - Ahmed Shendy
Do you mean the symbolic links at /dev/disk/by-label/*? - rodrigo
@rodrigo, mmm, I just found it now that any (previously) labeled USB storage that is connected to your system will get its label as a symbolic link under /dev/disk/by-label/. If It is not labeled previously, system won't create for it - Ahmed Shendy
But I don't know why if I do umount for the USB storage, its symbolic label gets deleted. I'm also can't see any details about my tablet. - Ahmed Shendy

Give this a shot:

udevadm info -a -n /dev/usbdevice

Further info:

udevinfo -q all -n /dev/sda

Still further info:

lsusb -v
lshw

Use the command blkid(8) to identify UUID, filesystem type, volume label, etc of your visible/formatted partitions in your system. It's used by the system scripts to collect information and mount filesystems, so you will have no problems in parsing its output.

If is already mounted and is any of the following types of partitions you could see:

mount -l|grep -E 'fuseblk|vfat|ext4'
