[CM12] Nexus 5 is not detected via USB when plugged topic

I have a strange issue, when i connect my phone over USB the computer does not recognize my phone, there are no options in the notifications, when i enable usb debugging the phone just reboots. When I enter TWRP and enable MTP there everything works fine. I have CM12 installed since the first nightly and dont know currently when the problem occured but I always flash the latest nightly available. I would like to prevent a factory reset to fix things.

Nexus 4 won’t boot up/work without charger plugged in topic

My phone is shutting down automatically after showing “google” logo. I went back to stock lollipop 5.0.1 but the problem still persist. It’s working fine with the charger plugged in. If I remove the charger after switching on, if I kept it idle, it will stay on till the battery is empty. But if I try to do something it will shutdown. In recovery mode it works well without the charger.
Please help me is anyone facing the same issue.
