Unable to connect with PC using USB connection after upgrading to Lollipop 5.0.2 I am using Micromax Yu Yureka. I'm unable to connect with PC using USB connection after recently upgrading my device to Lollipop 5.0.2. But it was working in Kitkat perfectly.
go to settings>developers options>and check the USB debugging option.(it should be on).This might help or try hard factory reset.
