first try lsusb in a terminal. See if it is being seen by the usb bus system. Or you can do a reboot and enter the boot order option to the bios and see if the bios is seeing it as an option for booting.

If after all that and the drive is seen; then your issue is in the os most likely.

Another thing you could try is booting a live version of your distro and see if that picks up the drive. If it does then it's your os not the board.

to mount the drive you would have to do something like this

cd /mnt or cd /tmp
mkdir dir_name
mount /dev/sd? /mnt/dir_name
or
mount /dev/sd? /tmp/dir_name

you may have to add additional stuff to the mount command like file system type for it to work.

The at91_ohci driver and hard disk negotiating configuration is failure. You need dip into why configuration negotiation is failure.

Hi,

in the configuration what I need to enable ............
I enabled USB Mass storage section in the kernel level configuration

Thanks

Do you enable SCSI disk and USB EHCI?

I have enabled

SCSI device support
Legacy /proc/scsi support
SCSI disk support

Support for Host side USB
USB Mass Storage support
USB Device File system
OHCI HCD Support


Where need to enable USB EHCI ?? I did n't see this configuration in menuconfig


Thanks and Regards
