Try using a different USB cable or different USB port.

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.

Same problem here, really can't figure this one out.. Tried all of the above too

Curious, in device manager under bluetooth it lists my Samsung s6 edge with a generic driver from Microsoft and I can't change it... Misidentified device? Do you have the same?

I assume your phone is unlocked/opened from lock screen when you are connecting it to your pc? ^^

Fully unlocked, & just no notifications :/

My phone isn't seen anywhere... not even in Device Manager

+#0808# is code for usb, you can try dial it (after last # it will run or not, depending on rom), or you can download Shorcut master from Playstore and try run it from secret codes inside app.
It has option to run it from dialer, or with SU if you are rooted, if you manage to run it, set AP and MTP+ADB to see phone as disk in windows, this helped me, hope it will help you.

It is the USB cable I had the same problem and changed the cable twice

Is it fast charging? Mine won't connect on any PC and also won't fast charge. I guess it's a damaged usb port..............

I have this same problem. My phone is not recognized by computer or any program. I was trying update TWRP and now i have samsung logo loop. Before i was updating i have sometimes problem with fast charging and computer dont saw mass storage when i connected phone
I changed completely module with usb in S6 but this dont resolve my problem. I used 3 different cable and changed USB port. I tried with windows XP and win 10.
any suggestions what i can do to bring to alive my S6?

Same problem here, started after updating to Marshmallow.

Exactly same problem with my s6 after 6.0.1 update! Sometimes phone will charge but it wont connect to pc/otg wont work but when i play around with MTP+ADB in *#0808#, s6 wont charge but instead it will be recognised by pc that usb connected not recognised and otg will work!!!!! always vice versa. right now my battery is empty and still wont charge!
---------- Post added at 08:13 AM ---------- Previous post was at 08:11 AM ----------
And looks like there is always a volt output through usb port and that time phone wont receive any charge

Really problematic.. I tried everything cables, drivers, different PC's and nothing.. tried my girlfriends S6 and worked instantly on my PC.
Only happened after official Marshmallow update,grounds for a return?

1. Power off your device (if it isnt already).
2. Connect to pc in recovery / download mode (just to trigger a response from pc /phone hopefully.
Do you know how to do this? If so, go ahead and proceed and see if the pc recognises your device in those modes
Let me know how that goes

Its not a usb port problem

Here are the usb drivers for those having issues. http://developer.samsung.com/technical-doc/view.do?v=T000000117
-Uninstall any previous driver relating to the phone (Also delete package if given the option). Disable windows Update aswell (Win10 Users). Also try install PDA+ from app store and http://pdanet.co/ to see if drivers will be correctly used.
-Make sure its a data cable, not a charge cable as only + and Negative wires are used and there is no way you can use a charge cable as a data cable.
-Connect phone and look for any pop up on screen, if anything pop up click it and see if it has anything to do with MTP or PTP.
-Still having trouble, reset firmware back to stock see how that goes, If not try boot into recovery and follow next step.
-- Once in recovery see if you can ADB push a rom over or a file, if that works then firmware is dodgy and something is missing. (Would recommend Android Tool kit to use this).
-- You could also try to install ADB insecure app ( Find it on XDA forums) and enable USB debugging and see if that will help
If you still can access file via usb when the phone is booted i would say to flash back to stock rom with ODIN and send it in for repairs. (Thats if you can get download USB mode to work)

Visited Samsung store, they said the USB port has failed but KNOX has been tripped some how, genuinely never rooted this phone or even attempted it but they showed me the warranty void status so basically even though they accept it's a hardware fault they won't fix it.
Sent from my (broken) SM-G925F using XDA Free mobile app

Quick answer for how I fixed this (sort of):
Go to "Settings" > "Developer Options" > "USB configuration". My phone indicated "charging". I selected MTP and my phone connected.
Why "sort of" - it reverts to "charging" every time that I connect the phone. I have to do the above all over again.
full history:
Same problem here. S6 on verizon network new in September 2015. Always connected without a problem to whatever computer that I have tried (linux & windows). The problem started after the recent complete software update on 2016-04-02. The phone is defaulting to "charging" and not trying to connect.
Go to "Settings" > "Developer Options" > "USB configuration". If "charging" is active, you know what your problem is. Select MTP (or whatever you need). The phone now connects and I can browse my files from my computer. The remaining problem, is that it reverts to "charging" every time that I connect the phone. Before the code update, there used to be a dialog asking me what I wanted to do (charge, data transfer, etc - sorry, don't remember exact options or how it was worded).
So, nothing to do with drivers missing on my PC. Nothing to do with need to install some other package. Nothing to do with a bad cable. Code was broken on a software update. (Or if you don't consider this to be broken, it was a poor software design decision).
!!! A CODE FIX IS NEEDED !!!

Weirdest Problem i had on a Phone ever.

Hello,
I'm having a problem with my Unlocked Galaxy S6 (SM-G920F) When i plug the USB to transfer data from my PC, it only detects it as charging, and yes, i know i should change to MTP in the notification center, but i don't get that option, I've enabled it manually in the developers option, also enabled USB Debugging Nothing. Then I've rebooted to TWRP , still nothing. Tried connecting via ADB Doesn't detect it.(I'm sure that cable works , tried it with my Galaxy S5 mini , it works), So i went to Download Mode, Fastboot commands doesn't work , but weirdly it detects in Odin. Good, not great. I've decided to revert back to stock, flsahed the latest firmware. booted still nothing just says Cable Charging as if it is connected to a wall plug.
I don't know what do now .
Any help?

Odd. Did you also try it on a different PC or another USB port on the PC?

My S6 does a continues connected/disconnected loop on my laptop but on a desktop PC it runs great. Other phones also run great on the laptop so it's possible that you too have an isolated case.
A dumb suggestion, did you try clearing the cache? Try downloading Samsung Smart Switch on your PC and run the built in device driver reinstall function.

I personally think that it's a computer problem rather than a phone problem. If you flashed stock ROM only and didn't touch anything special it MUST work because we would have seen people complaining by now. I'm still holding onto the idea to check the phone with another PC. IDK, maybe you somehow blocked the phone on the laptop? (Download mode and "OS mode" are different things so that would clarify why the laptop detects the phone in ODIN mode)

HELP! Can't connect to PC

Hi guys, i'm getting this problem and cant connect to pc and i think i've tried it all.
when i connect my phone to the PC, it stars charging but my pc doesn't recognize the device, and my phone doesn't show the notification to make it file transfer.
Could it be a computer issue?
it seems not, i've uninstalled and installed drivers (ADB and Fastboot, oneplus drivers, google drivers) and the problem persist, and even try it on another computer and its the same, the phone does not appear even on Device Manager.
Could it be the Cable?
I don't think so, i'm using the original oneplus cable, it use to work really well before, and i have even connect other phone with the same cable and the other phone is recognize by the computer, so it''s not a cable issue... but I still when to a Tech-store and try other USB-C cables with their computer but my issue still persist (phone isn't recognize, just charge).
Could it be a phone software issue?
Maybe? but i discover this issue 3 weeks ago and a i was on EVOX rom and i thought it would be solved flashing another rom, and i CLEAN FLASH Resurrection Remix Rom, but then the problem was still there!
cant connect even on FASTBOOT MODE...
BTW, before installing RR, i Installed OOS 10.3.4, and still my computer doesnt recognize the phone, YES i have enabled developer options and USB debugging is enabled, and USB PREFERENCES to File transfer, but its not helping me, the "usb for" option its all grayed out and cant change that.
Right now i'm stuck on a RR build without Gapps, and i lost ROOT and RECOVERY, and as you may think, i cant install any of them because i cant connect to my pc, so i'm in a pretty difficult situation here hehe, could you please help me out?

This helped me. Hope it works for you too

Thanks for your reply, but this didn't work because my device isn't shown on device & printers, or anywhere as far as i checked...

PROBLEM SOLVED.
I think this is the silliest solution I've ever seen, it was just DUST, i clean my USB-C PORT (with a mask xD) and then pluggin, AND VOILA, it worked!!! so keep your ports clean everyone
