Issue after upgrade to the latest version of OpenWrt Image for Yún - Ver 1.5.1

I upgraded to the latest version of the OpenWrt Image for the Yún Version 1.5.1 and used the easy procedure as instructed by arduino.
After the upgrade the USB LED stays on even after rebooting the entire board many times. Before the upgrade I only had the ON led lit when power was applied to the board. Now I have both the ON(green LED)and USB(white LED) lit with power is applied and a sketch is running.

Is this normal? Was this changed in the new image?

Thanks BJ

It's normal: see openwrt-yun/ChangeLog at master · arduino/openwrt-yun · GitHub
