This i happening correctly and blazingly fast. The /dev folder is
populated with a bunch of device nodes.
And no node for the cold plugged device (as we would expect)

# ndev -S
At this point, there is still no node for the cold plugged device (usbstick).

At this point, if i disconnected and connect the device again. There
is still no device node created for the usbstick.
and yes, in the usbdrive hotplugging script i am doing
MDEV_HEAD=`expr substr ${MDEV} 1 3`
which means that the hotplug script was being called earlier, but the
${MDEV} variable was empty, hence the expr syntax error.
