Dear Mukund JB:

  What did you do that did not work?
I have difficulty also, from time to time, mounting my
Compact Flash device using a CF->USB media reader.

  You may simply be missing the needed drivers.  :-|

I have 'usb-storage' listed when I:
# lsmod

  I first insert the memory device onto the reader.
  Then connect the USB cable to my computer.
# tail -f /var/log/messages

Jul 29 14:42:24 g2000 kernel: hub.c: new USB device 00:10.3-1, assigned address 2
Jul 29 14:42:27 g2000 kernel: Initializing USB Mass Storage driver...
Jul 29 14:42:27 g2000 kernel: usb.c: registered new driver usb-storage
Jul 29 14:42:27 g2000 kernel: scsi1 : SCSI emulation for USB Mass Storage devices
Jul 29 14:42:27 g2000 kernel:  sda: sda1
Jul 29 14:42:27 g2000 kernel: USB Mass Storage support registered.

Then I:

# mount /dev/sda1 /mnt/hd

# df -T

To show mounted filesystems and types.
Mine shows type 'vfat' for my Compact Flash -> USB device.

# tail -f /var/log/messages

To show errors

HTH, Chuck
