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 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.

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

Raspberry Pi has a dedicated SD controller which has nothing to do with USB. Probably that's why you can't get to it over the USB stack.
