My usb port is not working after system complete reboots on latest rom . If I revert system to 51.1.4.0, it work flawless. Once I install any of the latest roms either 51.1.5.0_515030720 or 51.1.5.0_515020820 it stop working. The strange thing is that while the system is on recovery it woks well. I have done a complete factory reset and follow all the steps to load newest rom like boot loader, unlock boot, CW latest version and nothing seems to work. I have search multiples sites and I can't find anybody with the same situation. Any help is greatly appreciated. TX
