[Q] OTG not showing up in File Manager topic

Hi, I am running cm12 for moto g. I am using the latest nightly of cm12. My problem is that whene I insert my OTG, it doesn't show up in any file manager. It only shows up in file manager only after rebooting my phone. After removing the OTG and then inserting it again it doesn't show up in any file manager until I reboot it again which is really annoying. Also there is no mount and unmount option under storage section in settings. Please help
