missing udev events

I am new to udev.

I am using i.MX35 eval board with LTIB and kernel 2.6.31.

I have cross compiled udev-142 for i.MX35.

Then i copied "udevadm" to the board and executed as below

    ./udevadm monitor

After this i plugged and unplugged the USB pendrive to USB hostport of the board. I was expecting the udev events and kernel events to happen and display messages accordingly.

But i was able to see only the kernel events happening no udev events happened.

I think i am missing something for udev events to trigger may be udev rules or something.

Please let me know what am i missing.


Below are the messages what I get. I get only kernel events not udevevents


root@freescale ~$ ./udevadm_142 monitor


monitor will print the received events for:


UDEV - the event which udev sends out after rule processing


KERNEL - the kernel uevent
