How to access the micro SD card reader on raspberry PI

I am trying to access micro SD card reader plugged in with a 64GB card but unable to access via Raspian.

pi@raspberrypi:/ $ lsusb -t
/:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=dwc_otg/1p, 480M
    |__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/5p, 480M
        |__ Port 1: Dev 3, If 0, Class=Vendor Specific Class, Driver=smsc95xx, 480M
        |__ Port 3: Dev 6, If 0, Class=Mass Storage, Driver=usb-storage, 480M
        |__ Port 4: Dev 4, If 0, Class=Mass Storage, Driver=usb-storage, 480M

There is another USB drive attached to the Raspberry Pi which I am able to access on /dev/sda1,

Plugging in and out I know that this device is attached at Port 3 and dev 6.

pi@raspberrypi:/ $ lsblk -t
NAME        ALIGNMENT MIN-IO OPT-IO PHY-SEC LOG-SEC ROTA SCHED    RQ-SIZE  RA WSAME
sda                 0    512      0     512     512    1 deadline     128 128    0B
`-sda1              0    512      0     512     512    1 deadline     128 128    0B
mmcblk0             0    512      0     512     512    0 deadline     128 128    0B
|-mmcblk0p1         0    512      0     512     512    0 deadline     128 128    0B
`-mmcblk0p2         0    512      0     512     512    0 deadline     128 128    0B

Not sure if the driver needs to be installed for this device before accessing it or I am missing something here?
