@Amar, in the kernel log, will find the information regarding where the plugged in USB mass storage device is attached to in the filesystem for ex: it can be either sda or sdb or sdc . Check and use mount command to mount USB mass storage sudo mount /dev/sd* <Path where you want to mount USB device> and after you can access USB mass storage. Below is the kernel log information on where the USB mass storage is attached to

In this case mount either /dev/sdc1 or /dev/sdc2 or /dev/sdc3 or /dev/sdc4 partition depending on which partition you are interested in.
