Check whether you've firs installed Samsung USB Drivers in computer. Install KIES and it'll automatically install the drivers.
Also check the USB Debugging mode is not checked in your phone. It'll be there in Developer Options

adb non detect.
Yeah. I am having similar problem. Pc wont detect my phone even when usb debugging is on or off. Installed all necessary drivers and still wont detect. In fact my note 8.0 having the same problem. It was ok a few days back. Is it the phone or pc that is causing the problem? Note 2 was derooted and 8.0 original fw. Can anyone help?

yes i have the same issue as well
i have no idea why

Try to do everything from the begining. Uninstall all previous drivers that you have installed. Restart your computer. You could download and install Samsung drivers pack only if you don't use Kies (search on Google for the latest pack) or download and install latest Samsung Kies suite and install drivers that come with it. After that connect your phone to the PC using your USB cable. When it starts to search for drivers open that notification and you will see something like >> Skip obtaining drivers from internet<< Then it will automaticaly install drivers from PC (the one that you have installated previously) or it will prompt you to point to the folder where drivers were instalated. I can't remember exactly how it goes but this is the solution that worked for me...And you must click on skip for every single item (on driver list) or it will not be instalated properly...

No, it's useless to reinstall driver, just buy a new usb sync/charge cable, that works for me.

What usb ports are you using?do you have a laptop,a desktop?
If you are on desktop,do not use front usb ports,usb hub,not.even an usb extension cable. Go for rear usb. Another data cable would do the trick too. If you are on a laptop,try to use another. Go to a friend or something. Sometimes,windows acts strange. Happened to me some time ago,couldn't make the damn thing install drivers for a xperia arc s,while on pc i did it in 30 seconds..after reinstalling windows,the laptop worked too.
So,bottom line,don't give up,just try other machines. It may a corrupted windows.

Step-By-Step: Get USB 3 Ports Working on Win 8 (For Issues With ADB/Fastboot and RR)

You need to install Win7's USB drivers on Win8 in order to get ADB/Fastboot working on Win 8. I drove myself mad until some kind soul here (can't remember who) provided the following link. Hope this helps some of you exasperated with getting RumRunner working.
Plugable

be warned, I have tried this 3 times already, and at some point throughout, on EVERY try, my computer would just STOP recognizing my USB devices, and I would have to use a recovery image on my computer because i couldnt log in to my desktop.
YMMV, but it didnt work at all for me

I made this guide. What I had to do was edit some Windows8 settings and install the drivers manually to get them to work.

This worked beautifully for me on Windows 8.1 RTM x64, thanks much.

I tried all this and still couldn't use Fastboot. My fix was in BIOS. I disabled xHCI mode in USB under advanced tab and everything is fine.

Worked great for me! Thanks!

Hi.I am creating a thread on this problem and I am using your idea on it and I will give credit to you too.
thanks alot.

Just wanted to let you guys know I got it working by installing pdanet. It installed it's drivers and everything worked after that.

My laptop has 2 USB 3 ports and 1 USB 2 port. fastboot/adb doesn't work on the 3s. I always use the 2 port and it works perfectly fine.

Guys the problems with windows 8 and windows 8.1 are normally the usb 3.0 drivers. Intel have not posted windows 8 drivers for series 7 and series 8. You need to modify the windows 7 drivers with other inf files. I have done the job for you so you can manually install the drivers.
The intel series 7 64 bit can be installed from here:

If you need signed drivers for your phone download htc sync from the htc website or use my link :

I wasn't aware HTC released 8.1 drivers. I will give these a try. Thanks!

I just made a usb stick carrying win7 to boot off of on my girl's win8.1 laptop. Works wonderfully, the only issue i had when using this guide was i had to manually set the boot sector after finishing running the application.

Cannot get Computer to recognize phone while in Download mode

Hello, I cannot get my computer to recognize my phone while in download mode, thus I cannot load a KDZ file to restore my soft bricked phone. I have the latest LG device drivers installed and have been able to transfer files before I bricked my phone (I accidentally wiped the OS in TWRP). Device manager states that there is a problem with the drivers. Is there anyway I can restore my phone? Thanks in advance

I have tried uninstalling the drivers many time and have also let Windows find the drivers itself but it says that the driver cannot be found.

Try a different USB cable and port. Have you got ADB installed? If so you should do a complete update of that too

Thanks for the help. but I finally got it to work by using a Windows 7 computer. I believe that there was something interfering with the drivers on my Windows 8 64 bit version.

[q] tablet not recognized by all computers!!!

Hi friends, I follow you every day and I love you!
I have a very big problem with my Note 10.1 2014 edition, that I can't solve. When I connect it to the computer (I tried 5 computers with different windows versions) it only charge the battery, but it's not recognised by kies or Odin. In Windows 8.1 it is shown as "unrecognised usb driver", in windows 7 too and it isn't seen at all in windows xp. I tried reinstalling kies, factory reset the tab, but without success. What can I do? I'm thinking about sending it in assistance.
Thank you and excuse me for my bad English!

When you plug in the tablet does it ask you (on the tablet screen) if you want to connect as a media device or charge only? Check your developer settings that you don't have debug mode set.

No, it doesnt ask anything...

Have you confirmed that you are NOT in USB debug mode?

Also make sure drivers are installed on computer. Sometimes it can take a few minutes to install drivers. When I first put mine on computer at work I had to manually install driver's.

Yes, i reinstalled drivers through kies application, but nothing

I have the same issue. I have been searching for a fix. I want to root but PC will not recognize it or pop up with anything, tablet only charges nothing else up on tablet. I have search and searched but nothing. I am also running windows 8.1.
*****
I have now tried a 2nd PC using all USB plugs. Installed Kies nothing, uninstalled and installed only driver still nothing. Clicked version 6 times on build number to get Developer options. I enabled USB debugging.
I am starting to get upset, I just want to Root for a few functions. It shouldn't be this difficult.
Anyone have any thoughts? It could be a simple thing we are over looking.

Change cable

Also try rebooting your PC .
My laptop stops finding USB devices after about 2 weeks.

Solved
I solved selling the tablet for 430$!

For those who are still having the problem, this solution worked for me on Windows 7.
I installed the first "Download" Link from here.
