I'm joining this group specifically to post my solution. I had working USB mass storage on 4.4.2 and one day it simply stopped. Tried restarting, did NOT have the extra menu in storage options so that was a no go. Here's what worked:
I'm assuming you've already enabled dev mode, and that USB debugging is on, as it was with me. I took the USB cable out. I turned USB debugging off. Then I restarted. Then I turned USB debugging on. Then I pressed the power button to lock. Then I plugged in the USB cable. And the options returned - Gave me my "turn on usb storage" option again. Here's hoping it helps one of you.
