I agree with mfillpot, and you could verify if that is the issue by specifying the absolute path to the binary as root. If it works, then thats what the issue is.

I'll bet a beer that's the problem :)
echo $PATH
Logged in as root and after "su". You'll see the difference.
Check /etc/profile and /etc/login.defs as well as /etc/bashrc or whatever files you might source on your login process.

You hit the nail on the head. your modification in bash_profile would be the cause of the problems, the proper way to append an entry to the PATH variable would be:
export PATH=$PATH:/new/path
please confirm that you typed it correctly, if you did not then your new path is the only one what is available to the user, you can confirm the PATH variable by explicitly calling the echo command with:
/usr/bin/echo $PATH

I would even go further
export PATH="$PATH":/new/path

I checked in /etc/login.defs and in bash_profile before and after "su' command. NO difference in both files.
Before I give "su", if i give the absolute path, "/sbin/lsusb" , it is listing the usb details. simple lsusb gives "command not found"
Before and after "su" command the login.defs and bash_profile is same. And, the PATH variable I added some two months back[the moment i installed slackware]. It worked well so far. for the past few days only am facing.
But, thanks to Mathew and deop for the PATH variable adding method hint. I did not know till see your posts.

I suggested to compare the $PATH variables under root and after "su", not the files (they will obviously be the same ;) ).
Anyway, glad you could solve the issue :)

what happened. For a long time offline mode.

still my doubt is,
I am logging in as root and the shell supposed to load root's profile only, right ?
"su" is also doing the same, [ logging in as root and loading the user's profile variables ], right ? or any other added things are carried out?
thanks, Good day
