usb – how to access the micro SD card reader on raspberry PI

I try to access a micro SD card reader plugged with a 64GB card, but unable to access it via raspberry.

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

There is another USB drive connected to the Raspberry Pi that I can access via / dev / sda1

Connect and unplug I know this device is connected to ports 3 and 6.

pi @ raspberrypi: / $ lsblk -t

Not sure if the driver should be installed for this device before accessing it or if something is missing here?
