MTP issue after UE40 update

I could not explore the idol3 using MTP after the update.
I keep getting this error:
Unable to access Android "Unable to open MTP device '[usb:003,042]'"

Interestingly, I'm able to work with adb.

ubuntu-linux:/$ adb devices
List of devices attached
XXXXXX device

I'm using ubuntu 14.04, havent tried in windows or Mac.
Any solution?
