I did some more tests. It looks USB controller is gone. Neither host nor slave USB ports work. I checked in recovery, fastboot and linux. I'm able to flash l-loader using serial headers and boot the board. It works well with the exception of USB :(
Can you paste the board boot log to see if it is able to find the usb hub?
