Thanks for
your help so far
It appears - things are working
and the real issue is that it takes like 5 minutes for my PC to actually
post the Drive Letter for the davinci board.
Any
idea why?
Basically, this is what happens
1) Connect the board -> Windows makes the 'ding'
sound and i see USB MASS STORAGE in the usb section of the device
manager
2) About 1 minute Later, A disk drive (file-stor) appears
in the Disk Drive column of device manager
3) About 5 minutes
later, a drive letter is assigned in Windows Explorer and I can use the
drive
Whats with that long delay? Some setting of
mine must be off somewhere
Thanks

You can find
loop.ko in driver/block
directory in the kernel src tree.

Hi
That's pretty much what I have done
Upto the loop driver part.
How do you install the loop driver?

It did

However, i
am back in the loop now where I can't see it under Windows
Its not
even in the Admin tools anymore like Jason first told me
Seems like
something isn't syncing/etc - any clues?

You likely need to
format the drive, in addition to creating the
partition, before a letter is assigned. Take a look under
Administrative
Tools -> Computer Management -> Storage -> Disk Management and see
if
it is there. You can format the drive using that tool as well.

1) #
create an 8MB USB file
dd bs=1M count=8 if=/dev/zero of=/opt/usbfile
2) # run
fdisk to set S=8,H=16,C=128 and then create and write an 8MB partation to
the
/opt/usbfile created by DD
3) #start USB Gadget
modprobe g_file_storage file=/opt/usbfile
4) Plug board in to WindowsXP host. I can see
the USB Mass
storage device appear in the USB section of device manager. I can see
the
linux file-stor gadget usb device appear under DiskDrives in device
manager.
Cant seem
to find it anywhere else. No drive letter assignment
Thanks for
any advice

Which command arguments are you using to install the module of file
storage?
