Have you tried downloading drivers for the S6? (Not entirely sure they even exist but I would assume they do)

right,sorry for the typo

You can find Samsung USB drivers here.
http://www.teamandroid.com/download-android-usb-drivers/
Alternatively, the drivers should automatically be installed when you install Smart Switch desktop app which you can get from Samsung's website.
Once the drivers are installed you should be and to plug in the phone and all should be OK.
I'd have thought that installing Kies would have fixed your issue so the above may not work but my fingers are crossed for you

Are you stock or modded?
Solution lies in the phone

b. it has 4 option there..
UART (MODEM/PDA)
USB (MODEM/PDA)
c. For USB. select the PDA.if it already selected to PDA. reselect it by select MODEM and then PDA again.. Only change the USB setting.. andthen press back. try reconnect

When you re-installed the drivers on your computer did you first remove the old ones? Or just run the install again? (Stupid question, I know, but I had to ask)
I've ran out of ideas the last think i can think of is restoring to a backup or odin back to stock...

installed over but Im pretty sure its not the comp because other devices work perfectly fine and regardless if drivers are installed or not the computer would detect unknown hardware
Uninstall the drivers then re-install them. I'm 99.9% positive that will work for you. For some reason they corrupt or something, and your computer wouldn't recognize it as new hardware if it thinks it already has the drivers installed.

Presume you are not connecting thru a USB hub? If not, try a reinstall of the Samsung USB drivers to your PC.

Initially connected through hub but tried direct of the comp, still the same problem.
Found this thread. http://forum.xda-developers.com/showthread.php?t=1727473&page=3
and tried the various fixes suggested, still no joy. Basically, MTP driver will not install, either windows or samsung's.
Guess I will have to return the item to stock once I've worked out how to do it.
Shame really as I would have liked to gone down the 'root' path, though being pretty much a noob to android hasn't helped.

Besides samsung kies, you should also uninstall and reinstall the correct drivers from the samsung website. Also sometimes something as simple as getting a new usb cable will fix this probem. Sounds kinda dumb but ive had samsung phones that work with one cable and are not recognized by another.

I've had that cable problem too, it was due to a cheapo "charge only" USB cable that came with a free charger... lesson learned!
[Solved] Odin doesn't detect your phone. Drivers error. Blah Blah...
Folks!
Your phone BRICKED???
ODIN Doesn't detect your phone???
Shows Driver Error Code 37???
Stuck in bootloop???
Well Well!
Everything is fine.
Don't just try all the solutions online.
The problem is installation of samsung drivers over and over again is replacing the existing drivers instead of wiping them out. So, the drivers have become incompatible with your device and as well as ODIN.
The solution is very simple.
Just reinstall your operating system of pc, install drivers and then You will definitely find what the magic with the drivers.
Hope you found it helpful...

Problem using odin

When i plug my p3100 into laptop in download mode the laptop starts to search for and install drivers. It installs one succesfully but then the next one fails and odin doesnt recognize the device. However when i plug it in normally ( not in download mode) it installs drivers fine and works normally. Can anyone help?
Thanks!

It is needed for Odin to communicate with your tablet. Yes it should.

The problem was connecting to odin. Done it in the end installed kies and it worked

How do I fix my Samsung A8 (2018) to get out of Download and Error screen?

I was flashing something onto my device and now I only get the "A error has occurred while updating the device software" screen and I've tried using Odin to flash the original firmware on os but Odin gives me this error: "Can't open the serial(COM) port" I tried every fix and none of them worked. Can anyone help me to fix this?
Did you install the usb drivers first? If not here:
http://www.mediafire.com/?6onrjbyd46j4lhj
try a different usb port on the computer, and if that doesn't work try a different cable.
Do you have samsung kies or smth installed?
