[root@tech29 bus]# which lsusb
/usr/bin/which: no lsusb in (/usr/lib/ccache:/usr/lib/ccache:/usr/lib/qt-3.3/bin:/usr/kerberos/sbin:/usr/kerberos/bin:/usr/lib/ccache:/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin:/usr/src/jre1.6.0_24/bin:/home/users/ajeesh/bin:/usr/src/jre1.6.0_24/bin:/usr/src/jre1.6.0_24/bin)
