This Thread is recopiled info from web and xda, thanks to xda forum and to Nisiomorais who helped me in fix this weird issue.
You must do this only if your IMEI its shown 000000000000000 or similar.
Disclaimer:
I´m not responsible for a phone damage or bricked by doing wrong this method. You must do this exactly as I wrote and will be no risk of any issue.
1-Download EFS Professional from here:
http://forum.xda-developers.com/showthread.php?t=1308546
Thanks to lyriquidperfection for this wonderfull tool.
2-Download QPST installer
http://forum.xda-developers.com/showthread.php?t=1946915
Thanks him again.
3-Download Samsung USB Drivers
http://forum.xda-developers.com/showthread.php?t=2038555
4-Flash Original Stock Firmware for prevent issues. See on the forum on how to do that if you don't know.
5-Use the Original Samsung USB Cable.
Procedure.
*Read carefully before doing some of the tutorial down below*
1-Write down your Original IMEI from the back of your Phone, it has to be on the back of the phone, below the battery.
2-Install Samsung USB Drivers
3-Connect the Phone by the USB cable to the PC using only one port.
4-Let the PC do some recognition.
5-Put Phone into USB Debug mode (Settings>Applications>Development) and let it do again some recognition and configuration of the USB port.
6-Unplug and replug the USB using same port.
7-Dial *#7284# and choose "USB" Option to enable Diag mode
8-Open EFS Professional, Choose Qualcomm NV Tools
9-In Available COM Ports it has to say "SAMSUNG Android USB Diagnostic Serial port (WDM)"
10-Remove Send SPC and Read Phone Marks.
11-Clic on "Connect"
12-In The Phone Mode category The "Online" Tab has to appear to be Enabled now.
13-In the Category "IMEI Repair" Put the IMEI that you have to the IMEI Box.
14-Go to "Write To:", choose in the tab "Device", and then clic on "Write". It will appear "IMEI Succesfully Written".
Reboot.
FACING PROBLEMS WITH THE USB CONNECTION.
This procedure can be done if diag connection fails, but i'm not sure if this method do the trick with the USB recognition issue. I've done the two methods and it worked for me. You can choose to do one or the two together. Nothing to fear by doing the process. Its safe.
Put the phone on USB Diag mode by dialing *#7284# and choosing "USB" Option.
Install QPST installer, and open "QPST Configuration", go to "Ports", and "Add New Port...", choose the port and close the program.
Now open EFS Professional and do the steps that appeared above.
Hope it helps, so sorry for my english. I´m from Chile.
Awesome sir :fingers-crossed:

Yes
Try with Nexus Root Toolkit. There's the function "Full Driver installation guide" that helps with drivers problems

Have you followed perfectly the first step?
Code:
Step 1: Uninstalling Previous Drivers (If first time skip to 'Step 3').
To ensure driver configuration goes smoothly, it is advised to first remove any previous drivers you may have already attempted to configure:
1.) Plug your device in with USB debugging enabled
- Settings > Developer Options > check USB Debugging
2.) Launch Device Manager using the button bellow.
- Identify whatever device resembles your Nexus and right click it
- Select 'Uninstall'
- Check the box for 'Delete the driver software for this device'
- Select 'OK'
3.) Unplug your device and Launch USBDeview using the button bellow
- Use USBDeview to uninstall any;
- Android ADB Interface device's,
- Samsung USB devices,
- Google USB drivers
- ... or ANYTHING else you see that resembles your Nexus.
- In particular look for devices with Vendor ID
- "18d1" or... "04e8"
- Simply right click these devices, and select the option to:
- "Uninstall Selected Devices"
4.) Reboot your computer (recommended) then proceed to step

Yep,I did everything as stated in the instructions
True, could be for the specific device that the identification leads to non-usable drivers. Best to clear out all of them from your PC and start again. Personally, never had this issue with a phone (well a yunos phone that was a ------), but never an android phone. It is still the best bet. You said other devices work, so it must be working, but something is messing with your device. Have you tried on another computer, plug, port...?

Yep,Tried it Windows 7 second after connecting writes that the "device has been disabled"
I have a suspicion that the phone automatically blocks the connection
Are you using Android stock or a ROM?
Maybe you can try a factory reset of phone

I've tried Android stock and ROM
I did factory reset and it did not help
From the past 2 days, I am trying to connect my samsung galaxy grand 2 (g7102) with my pc, but unfortunately, its not detecting my phone. And I don't even have a clue whether it happened because of me or not..
I've already tried several steps to solve my prob but none of them worked.
Like-
1. Rebooting the phone, clearing cache n dalvik cache.
2. Uninstalled all its drivers from computer and reinstalling latest one's.
3. Installed Kies3 to check its discoverable or not.
4. Changing modes from mtp to ptp to adb.
5. Cleaning off the pins and using its original data cable.
After these steps what I found out is that after fresh installed drivers it attempts to install its own driver which takes too long but after installing it does not get detected in my computer but rather it shows up in device manager with name "SAMSUNG_Android".
I know it cant be rom (Note 4 Alpha S6 Revolution) issue or anything like that, but also i believe its not pin broken issue as it is charging plus when i uninstalled all its drivers it tries to reinstall.
So please help me out and suggest something .
Thanks in advance .
Phase 1:
1. Open Settings
2. Goto "System"
3. Goto "About Device"
4. Goto where it says "Build number"
5. Tap that 10 or so times.
Phase 2:
1. Go back to the "System" tab in settings
2. Click ''Developer Options"
3. Enable USB Debugging.
4. Profit.
Hope this helps! :thumbup:

1. Deactivate "Reactivation Lock" from settings.
2. Re-Flash your firmware with CHC not CHC_Home.
3. Now setup your Device with Full Information. (if network and Data Connection didn't work than you can setup without info. Reactivation lock disable works here to setup your device without samsung ID if your network fails)
4. Now set all things and Turn on Developer Option.
5. Now disable Apps Verification and turn on USB Debugging.
6. Now Login your Samsung Account and Restart your Device.
7. Now verify OTG. it will work fine
Here are some cache memory remains in Connector after flashing, Data transfer and Dual working cable.
and any Device should be reset after 2 to 3 Months. That's why OTG Stopped working
