Yes, another DRIVERS DONT WORK thread..

Hey guys, just got my Tab a few days ago, its unlocked and its working great. I want to root, but my PC wont recognize it (running win7) and it says the USB device has malfunctioned... wth? I searched through some threads about the drivers, and ive tried 4 different ones, restarted my PC, AND my Tab, with no luck. No, USB Debugging is not enabled. (not a noob, just, simply not working)
Any ideas? I would appreciate it

I just got my tab 3hours ago. I got it to work.
Here are what i've done
1.go to control panel and see if samsung usb driver is there. If it is, uninstall it.
2.disable usb debugging on the tab
3.connect the tab to the computer.
Thats wht worked for me. Hope it helps. And yes, samsung has really got to work on the usb thing.

Unzip and run the attached file. Delete any old unused USB device and delete any Android, Samsung or other related device then reinstall Samsung drivers.

This helped me: my computer tower has front and back USB ports. Back USB ports are directly embedded in the motherboard, front USB ports are a wire run from the case plugged into the motherboard, but the front USB ports are on a different chip.
When I first tried using the ADB debugger with Android, ADB would not even find my device if I plugged the device into the front USB ports. If I move the cord to the back USB ports, everything works properly. Maybe this is your issue?

Thanks guys, I believe I got it working.

[need help] usb device not recognized!!!

hey guys,
I don't know if this still a problem with people. but I'm on win7 64bit and I can't seem to connect my nexus s, to my computer. I always have to upload from computer to dropbox then download the file from DB on my phone... usb plug doesn't work. I tried the same cable with my wifes Samsung vibrant and it recognizes it, but when i plug in my nexus s the debug icon shows up on my phones status bar for like 1 second and disappears. then window on my compter says "USB Device Not Recognized"
need help please.

What does it say in device manager (in windows)? Maybe the driver is wrong...

do u have a right drivers installed
have a look here and check Google USB Driver

I'm having the same problem. I have tried both my computers and multiple cables but I continue to get the error. When I try to update the drivers or reinstall them Windows says the drivers are up to date. I've tried every USB port on both computers as well.
I even took the phone into a repair place to see if perhaps the USB port on the phone was malfunctioning and they couldn't find anything wrong with it.

Try installing pdanet, I had a similar issue when I rooted my ns and installing the pdanet drivers solved the problem.

I've been having the problem also and none of the fixes worked. Not even PDA net. You'd think that the more people have this problem so one would have found a real fix by now.

I can't get the PDAnet drivers to install - during the installation process, my phone has to plugged in, which of course the installation program can't see.
Weird thing is if I remove the battery and then plug the usb in and start the phone, the drivers show up in the device manager but they always disappear before I can unlock the phone - appears the USB connection on my Nexus S is broken...can;t think of anything else.

[Q] Windows will not recognize Note 3 anymore, help please!

Hey guys,
Just recently, my PC and any other PC Ive tried for that matter will not recognize my Note 3. I had Windows 7 and it worked fine for months, then just the other day it came up on the bottom as USB Device Not Recognized, and no matter what I do it will not do so. Yesterday, I upgraded to Windows 8.1 and still the same result. I have installed Kies 3, uninstalled and resintalled Samsung drivers and still nothing. I am running a custom rom in the stock slot using Safestrap...is it possible that that might have messed up something? Even when the cord is plugged into the PC, the phone doesnt come up with anything notification that it's plugged in, but it does say it is charging. If any of you have any tips or something please help because I am at my wits end.
Thanks

Have you tried with another cord?
Computer doesn't see device... Device doesn't detect plug in... Sounds like a bad USB cord

Yes, actually I have and still nothing...forgot to mention that in the original post.
It's a strange problem which leads me to believe that something has gone wrong in the phone, or that I caused something to go wrong by flashing a rom or three, since it did work previously. Unfortunately, I'm at status: Custom, although my Knox is 0x0.

Yes, this shows as disabled. What should this be?

Can't help you solve your problem, but last night I had a hiccup where I plugged my (17 day old) N3 into my computer in a USB2 port and ... nothing at all. (As if it were electrically disconnected - no "unknown devices" showing)
Tried it in a different USB2 port, and ... nothing.
Tried in in a USB 3.0 port - same computer, same OEM cord - and everything was fine. As far as I knew, nothing had changed on either end of things, although the previous evening I had used a different OTG cable for a USB key with the phone, and I had also had a automatic update of the Samsung Push Service on the phone. Nothing had been plugged into the PC's usb ports since it's prior cold boot. (Win 7 x64 Pro).
This morning (both PC and phone have been rebooted), everything is back to normal - both on the phone and the PC. Both the USB2 and USB3 ports all seem fine.
Ugh. Makes me nervous - brand new hardware.

Boot into Odin mode THEN plug the device in, let windows find the drivers for it then once that's done, reboot the phone regularly and see if it works then. It appears to be an issue with most to ALL Samsung devices, but this worked for my wife's galaxy S3 when the computer wouldn't recognize it and the phone didn't detect a PC connection.

Did you fix this problem?

Thank you! Worked perfectly!

I have the same problem, do you have any solutions ? Thanks.

I too have been struggling with this problem. The is no USB symbol in the notifications area on my phone whether I plug into to my computer at work (Win7) or at home (Win7), using a usb3 cable or a usb2 cable. Its as if there was a setting on my phone that allows recognition when plugged into a computer that has been turned off.Is there such a setting? I would love some help on this as well. Thanks in advance! I am rooted with towel root and have had no problems until last week. When I look in the device manager on my computer it shows :
SAMSUNG Android Phone
SAMSUNG Android ADB interface
I tried uninstalling the above and then plugging my phone back in and it re-installs the same driver shown above.
For what it is worth here are the drivers for SAMSUNG Android ADB Interface:
c:\windows\system32\DRIVERS\winusbsys
c:\windows\system32\WdfCoinstaller01007.dll
c:\windows\system32\WinUSBCoinstaller.dll
Should I be using different drivers ? Thanks|!

please help!
any solution yet? i have same problem, no usb detection and camera wont work i want to flash stock rom whit odin but i cant get the computer to recognize my phone...

I was able to fix the usb recognition problem. i had to do a factory restore. I lost root but gained usb recognition AND the Over the Air update to 4.4.4 and patiently awaiting the update to 5.0 hopefully this month!

PC won't detect S7, all conventional fixes exhausted!!

I've got 5 S7s on my desk, all Canadian variant, all from the same manufacturer all the same model. - SM-G930W8
All are recognised by my PC but one and I can't work out why not!
Plugging the phone into the PC makes no noise from the PC but the phone seems to detect a regular charger not a PC.
I have plugged it in using different cables including the one in its box and the ones used on other devices that were recognised and only this phone doesn't work with any of them.
I have plugged in, unplugged and rebooted many times.
I have set the USB configuration to MTP (Media Transfer Protocol)/Transferring files.
USB Debugging is ON and OEM unlocking is ON.
I have tried booting into stock recovery and wiping cache AND factory resetting.
When phone is turned on "adb devices" returns nothing.
I have installed Samsung Kies and Samsung Smart Switch to reinstall the drivers.
NOTHING IS WORKING!
All threads I find tell me to do the things I have listed above and have people saying these have worked but all of them I had already tried and double tried and nothing is working.
The cables are correct and working with other S7s of the same model.
All the correct drivers are installed and have been uninstalled and reinstalled.
All the correct setting are selected and OEM unlock and USB debugging enabled.
Phone was fresh out the box as were the other four and all cables.
Samsungs apps installed on PC to ensure best drivers installed.
Would really appreciate some guidance or consolation that its not something stupid I'm doing! I work with these phones everyday and this has never happened! Just banging my head against a brick wall trying to resolve it

maybe faulty usb port, my nephew had S6 with the same issue, service replaced usb port and it started
to work with PC.
try download mode and see if odin see your phone.
try to move the cable a lil bit and see if sth appears for a second.

Thanks but unfortunately Odin doesn't recognise in download mode.
Could it be a USB port problem if I used the same port for the other 4 devices and have no issue?
I'm considering sending the phone back to manufacturer to be honest I think it may just be a faulty device or something!

I bet its microusb port fault

Had a similar issue on Windows 10 , if that's what your running let the phone be connected, uninstall the driver from device manager, and then install driver select have disk and select the basic mtp , if this doesn't help connect to Microsoft support and they'll guide you through it , worked for me , my phone used to detect on other laptops but mine , also I could connect other phones on mine but not my phone, hope this helps

same issue here

Usb drivers issue

Nexus 6p 128gb, latest PN7.1 rom, carrier is project Fi. Working fine as is but I'd like to try out 8.1. Plus, I can never get file transfer mode to work, irregardless of what does or does not install below.
I can't get the drivers working properly on my windows 7 pc. On two different machines.
What I've tried...
A. First uninstalling any /all android drivers via device manager as many guides suggest.
B. Plugging in with debugging off. Drivers installed but not adb.
C. Plugging in with debugging on, all drivers fail to install.
D. Installing via the sdk. Still tries to install the drivers and fails when I plug the phone in.
E. Installing the drivers via the Google provided USB drivers file. YES the authentic ones. Windows won't even recognize those. When I point the drivers installer to the folder where I unzipped them, it just says it can't find any drivers.
Is there any chance I could have jacked something up in the phone whilst screwing around with twrp, xposed, Magisk, etc in the past? Maybe a bad vendor image or something? Please help. This is making me insane.

Try a different Usb cabel sounds like the one your using is faulty.

Problem somewhat solved. It wasn't the cable. Something was screwed up in the works. I did a factory reset and got it to work on one of the two PC's I was working with. After that I was able to identify the phone with fastboot and do what I needed.
I forgot to include the fact that I was working with multiple cables because I had the same thought. I was using
1. Inatek 3.1 Gen2 cable
2. HI-CABLE
3. That stock little 8 inch cable that came with the phone.
