Welcome to Android Central! Which phone do you have? So you're saying that yesterday you could connect the phone to your PC via USB successfully, but today you can't? Have you tried rebooting your phone and your PC? Have you tried a different cable?
Welcome to Android Central! Which phone do you have? When you connect via USB, swipe the notification panel down--do you see a USB icon? If so, tap it and make sure it's set to MTP.
