After you plug in your USB device to your USB port, Linux system adds a new block device into /dev/ directory. At this stage, you are not able to use this device as the USB filesystem needs to be mouted before you can retrieve or store any data. To find out what name your block device file have you can run fdisk -l command.

root@iplog:/media# fdisk -l

Disk /dev/mmcblk0: 7458 MB, 7820279808 bytes, 15273984 sectors
238656 cylinders, 4 heads, 16 sectors/track
Units: cylinders of 64 * 512 = 32768 bytes

Partition 1 has different physical/logical end:
     phys=(491,254,63) logical=(492,20,40)

After you plug in your USB device to your IPLOG unit, It will add new block device into /dev/ directory. To verify it, use the following command.
root@iplog:~# fdisk -l

USB will start with name SDA
