why my device is showing as unauthorized device???? - Galaxy Grand 2 Q&A, Help & Troubleshooting

I am using galaxy grand 2. Gennext rom
when i try to connect my device to PC for reverse tethering my device is shown as unauthorised device.
i think problem arises due to some problem in USB debugging because whenever i connect my device previously it always asked for Allow USB debugging.
now in this rom it does not appear for a single time.
as i love this rom very much i want you to please solve this problem for this Gennext rom.
Thanks.

[Q] GS4 i9505 usb-pc issue after upgrade to JB 4.3

Hello everyone,
I registered and post this thread because i give up with problem i get after upgrade my galaxy s4 i9505 to jelly bean 4.3. Pc dont recognizing phone, usb cable is good because when i connecting the charging icon appears. I checked in other pc (in both there is windows 7), I download the last version of usb drivers from official site, i download the last version of Kies3 and it still no connecting. Before upgrade i havent this issue, i also checked other usb cable (both cables are original). I searching for hour any solution, activate developer options and check "usb debugging", also i wrote *#0808# and check mtp (i also tried other options, no result) or I tried launch vol down + power + home, also dont help. So i give up and now i`m hope some hi-tech wizard will tell where i making mistake...
After hours spending on wasting time with this usb connect i started to think about change soft, but here appears another issue... I havent root, and superuser. That is not a finish of trouble! I noticed that i have recovery 3e with some kind of error "e: signature verification failure" when i trying to flash any other soft or custom recovery! I searching for some tips on web, but in all options i allways impended whatever i try: when i try use Rom Manager there is error i havent su, when i try activate SuperSu there is error i havent root, when i try install CWM by MobileOdin there is error i am not su... when i try other aps like Framaroot there is error #5, also in Rom Manager i have info that my Rom doesnt support OTA, when i try change recovery file in System/bin folder by RootExplorer there is again error "u havent root"! I'll go crazy by this trap!
Anyone have any ideas? Please help me :crying:
PS. English is not my strong side. Sorry.
So... can sombody help me or this issue is too much advanced for this forum?
Again please help me.

I see the problems are in Windows 7. The USB Conector seems ok. Untick "usb debugging" in ur phone and take a look this page. If dont appears nothing in the device manager, tell me it and i will give ya other solution
EDIT: Other option is:
- Uninstall completely Kies and Kies 3
- Reboot ur pc
- Download the latest version of Kies 3 (drivers are included, only tc what u select in the installation -> dont untick them)
- Conect ur phone to the pc with the USB conector and wait coz the drivers have to be installed. Till Windows dont finish of install them u dont need touch nothing. Good luck
I'm suprised that three peoples trying to help me, thats charming, thank you.
But...
Repulsa I've done what u wrote, I tried plugging s4 to another usb port, one port usb 2.0 and another usb 3.0, always was the same situation, the charging start coming but nothing more, there is no notification on phone screeon or on the pc. Also I tried do this in second pc, in 3 usb ports, but always was the same. After that I tried that what Repulsa and jaswinsky says, i re-install kies. First I uninstall in both pc kies, and i install the kies 3, I reboot my pc and I reboot my s4. Nothing new happens, only charging. Here i want to turn your attention that, I checked in both pc's my younger brothers Galaxy s2, and it havent any problems with connecting! If I plugging Galaxy s2 in this usb ports in both pc, windows 7 havent any problem to recognize phone! Kies and "My Computer" shows the device memory and its working. When I after that disconect s2 and plug in my s4 the same situation happens. Only charging icon, and nothing appears about connection.
After that i tried that what Joku1981 wrote, I untisck "usb debugging" in developer options and i checked the device manager, but there doesnt appears anything. There is not "other device" warning or anything like that. Charging icon appears but pc dont recognizing s4. I would also like to point out that, yesterday I've done with younger brother the format on one of this pc's with hope that will helps but, we format pc, reinstall windows7, reinstall all drivers, and the situation is still the same.
Please help me!
PS. I'm starting think about that the official OTA update do 4.4 will solve the issue..

Then it's either a dirty usb port or a broken usb port.
