Thanks Zogzog
I have compiled the kernel with gadget drivers.and i want to see the
micro2440 as hdd on the host pc when connected by usb..Micro2440 is
detected as a unknow device in hostside.I am new to the linux device
driver..Guide me with the steps.

nop, I'll not, 
because I've already send you a link with the documentation.

to be precise, what you need is here:
http://www.linux-usb.org/gadget/file_storage.html
Where you can find a good explanation and a step-by-step example......
far better than anything I may write here.

PS: if your kernel support iso9660 you can directly use an cd_file.iso as a
read only backing storage file. (but sadly not bootable by any bios, ...
that's my problem).
