### Read SD memory card information 
```
$ sudo udevadm info -a -n /dev/sdb
```
SD card vendors should be in ```/sys/class/mmc_host``` within ```/sys/class```

Try searching /sys for some MMC (SD) specific keywords for ARM-based embedded system

```
$ find /sys -name "oemid"
/sys/class/mmc_host/mmc0/mmc0:aaaa/oemid
$ find /sys -name "cid"
/sys/class/mmc_host/mmc0/mmc0:aaaa/cid
$ find /sys -name "csd"
/sys/class/mmc_host/mmc0/mmc0:aaaa/csd
```

Another way:
```
# lsblk -o name,serial,uuid,partuuid,label,partlabel /dev/sdb
```
```
# lsblk -o name,serial,uuid,partuuid,label,partlabel $(blkid --label MY_MICROSD)
```
