Android Accessory works only with MTP/PTP/USB Debugging on

Question

When using a rooted Nexus 7, The phone only identifies as an accessory when USB Debugging mode is on. I don't have this issue with a cyanogen mod phone (both running 4.3). How can I make the phone respond as an accessory when Debugging is turned off?

EDIT:

The issue is the Android tablet only connects when MTP or PTP USB Computer connection is on, or if USB Debuging is on. It doesn't show up as an accessory at all otherwise.

SO - New question - Can you add an accessory type to the USB Computer connection, as I don't want the tablet to connect as neither MPT nor PTP? I especially don't want the device to have to be in debug mode for it to be identified.

I had a similar problem with my "galaxy s4 mini". I did the following and it works for me:

Note: It works for linux (Ubuntu's distribution).

Open your console and run the following command:

$ sudo add-apt-repository ppa: langdalepl / gvfs-mtp
$ sudo apt-get update
$ sudo apt-get upgrade

Reboot and ready. I hope this helps
