Is all of the code in the same script.. e.g. did you export DEVNAME if it's not?

If you set DEVNAME manually, after (or in place of) the fdisk command, there's no reason that the output would be
Code:
mount /media/usb/test

instead of
Code:
mount /dev/sdb1 /media/usb/test

If the variable DEVNAME is not created as read-only, or you're not running the script in a shell jail, that is.
Yes Sir you right the output
Code:
mount /dev/sdb1 /media/usb/test

but mounting is not working

Generally speaking, to mount a filesystem, you need root privileges. If you're running your script as a non-root user, you can get root privileges for the purpose of mounting the FS, using sudo. If you administer the system you can easily do this by adding something to the "sudoers" file (with the visudo command, not vi), for example, from the sudoers file in CentOS 6:
Code:
## Allows members of the users group to mount and unmount the
## cdrom as root
# %users  ALL=/sbin/mount /mnt/cdrom, /sbin/umount /mnt/cdrom

is replace my user as
Code:
root

sir? In my visudo put this
Code:
root ALL=/sbin/mount /mnt/cdrom, /sbin/umount /mnt/cdrom, /bin/fdisk /bin/grep

is this right sir?

OK, it's late and I need to go. Let's speed this up.

Are you root? If you are, what error do you get when you try to mount the filesystem manually? A media error, an unsupported type error, an unknown / unsupported FS type error, or what?

Please try to be more forthcoming and communicative with information so we don't end up with a War and Peace-sized thread for what is probably a simple problem.

If you're not root, then the sudo rule you need to add should be for the user you want to allow to be superuser for the purposes of running the command - which won't be root, as root doesn't need sudo to run anything - the su in sudo means super user.. root is already a superuser.

Code:
/dev/sdb1 /media/usb/test
