[Q] USB Device Not Recognized [Unrooted]

Hello everyone,
My pc won't recognize my samsung galaxy note 10.1 GT-N8000 *4.1.2 Android version* and also on Kies
Already tried: -Reinstalling samsung device on PC
-Restarting the device (samsung galaxy note) as well as the PC
-Kies installed
PLEASE HELP!, I WOULD REALLY APPRECIATE YOUR REPLIES
BTW, here's the screenies ↓

Try a different usb cable... Sometimes it can be that...
Otherwise re-download the usb drivers and try that.. They can be found in dev section, a quick search will find them...

The problem is that u are using a hub port on your pc or a deffective one try another one and if you have another data cable to ensure that the problem from the pc and not the tablet

If changing the cable/port did not work try the following:
1. Bring up dial pad
2. Dial *#7284#
3. Select Qualcomm USB settings
4. Make sure MTP is selected, if it isnt, select it and click ok button
5. Reboot Phone

AP : G920FXXU2BOG8
CSC : G920FOJV2BOG8

The pc doesn't recongnise it on device manager (i have a win 7 pc), the phone however react as pluged in a charger.
their is no mtp or mass storage switch on notification.
i have reinstall the driver of samsung several times with smart switch & also made it manual by suppressing directrly the samsung usb driver from programs on control panel then reinstall it but no hope.
I can't figure out eitheir its hard or soft.
i had change my cable & also test my pc with another Galaxy s6 it works fine, but mine no.
i have made wipe cache / factory reset also made an initialisation from parameters the phone is formated but not recognised by the pc also test it on another pc but the same behaviour windows pcs doesn't recognise my phone.
However, i figure out that when its on the restore mode (volume down + lock + home) the pc recognise it by Odin and smart switch.
i install the same rom on it also made an emergency restore with S/N and model and the process completes fine with smart switch and i saw the donwload progress bar completing on my phone.
but still i m stuck its not recognised please help !!!
i tries to use *#0808# and its on AP / MTP + ADB but no hope

i used different cables and pcs but still not recognised
yesterday i used odin with those options :
BL/AP/CP/CSC and checked
Auto-reboot
F.reset Time
phone EFS Clear
Phone bootloader update
it has taking some while to execute but after that my phone was working and detectable again by my pc the problem was resolved for a couple of hours, in the evening the problem occured again.
and i have tried the process again the same why but no connection at all.
i don't know if its a hardware problem or software related problem
because the usb work when i m in restore mode (Odin mode) otherwise no.
Its an advance problem i already check all about usb / cable and pcs related problem.

Problem resolved
I sent my S6 to Samsung SAV it take them 4 days.
they doesn't give me proper answers on what they have done but i saw that my mini-usb plug is new so i expect that they got this part changed accrodingly the samsung has no sign of damage its a clean operation.
Its now detectable. It was indeed a Hardware problem

i have the same issue but in a g928f
today i changer my lcd with the micro usb flex
so all is new except the main board and still is not recognised at any pc with any cable.
i am really starting to feel very sorry for this phone.
odin does not see it at all even at download mode.
i don't know what else to do.

Software or Hardware Issue
I have a s6 920t that I am suppose to pay for at the end of the day. I got it from a friend who bought it while overseas. The only time my computer detects it is in download mode/odin mode, I hear the sound and I see it as "Added". When I try to connect any other way I don't hear the sound my laptop makes when it has detected a new device also otg cables don't work. I just simply want to know if this a software or a hardware issue? Software I can fix but if it is hardware I don't want to waste my money. Please anyone reply as soon as you can so I can decide what to do.
Thank you

I have two S6 Edge and one of them started doing this (phone only appears on USB when in Download mode). When swapping the motherboard between the phones, it works. So the problem isn't with the motherboard, but the USB connection module attached with the ribbon cable... There must be a chip on the module which gets locked somehow and replacing the board is at least one way to fix it. Hopefully someone finds another method without replacing the charger board?

Galaxy S6 won't connect to PC or MAC

Hi,
I have a problem with my Samsung Galaxy S6 - SM-G920F, it isn't recognized anymore by my PC. This happened after I made a ".nomedia" file to hide some gallery files. I deleted the file but the phone isn't recognized by any PC. When i connect the phone, it is only charging.
I installed TWRP for using the mount feature - not worked.
I installed the latest USB drivers from Samsung - not worked.
I installed Samsung Kies3 - not worked.
I installed Smart Switch - not worked.
I dialed *#0808#, turned MTP - ADB - not worked.
I installed through Odin a stock 6.0.1 Rom from SamMobile - not worked.
I turned on/off the USB debugging - not worked.
I used more than 3 USB cables - not worked.
Device Manager isn't recognizing my phone.
McBook Air isn't recognizing my phone.
The phone is not rooted and it has 4 moths since i bought this phone.
Is there something that I missed on my attempt to solve this problem?
Thank you for your time.

If you learned to read the forum rules, and abide by it, you'd have an answer. But until then forever wonder why your phone won't connect to your pc.

Z5 not recognized by PC via USB

Hello,
I've been trying to charge my phone through the USB cable that came with the device. It works with the charger, but once i plug it into my pc it doesnt work. When I open Sony PC Companion it doesnt recognize a device either. Now when I enable USB debugging, it works for 2 seconds and then it goes back to non functioning. What i mean by it works for 2 seconds is, the device gets recognized by sony pc companion but then gets unrecognized immediately, i get the charging icon for 2 seconds en the device says its connected to the pc via MTP. But then I can't do anything with it. In device manager it has 2 unrecognized devices: ADB interface and MTP.
What is wrong here?

bump

Try another cable if you have one.
Also install the drivers for your phone from this site.

without recognizing charging function must work!
but test this >
uninstall PC companion > then go to drive C/Program Files and Files x86 and delete Sony and Sony Mobile folders (if exist)
then restart and Install it again.
If doesn't help
Read this carefully

Last week I found a solution, the universal adb driver from Google fixed my problem. The driver from Sony doesn't work, but this one does!
