What is the command to find SD card UUID on Linux ?
BTW: My SD card is not a USB device.
You don't say which distribution you have.
usb-devices returns serial number information (if available) for all usb devices (on Debian, root not required).
You could also try (as root, or via
udevadm info -a -n /dev/sdb
changing the device to the SD card reader device. This requires your Linux distribution to support
The pretty common
lshw (again, run as root is best) might also return the information (untested here).
I found this command :
lsblk -o name,serial,uuid,partuuid,label,partlabel /dev/sdb
