I really hope you found a solution. Ive been looking an answer for this annoying problem for 6 months!
Ive read almost 50 threads in differents forums about this problem but no solution at all.
- Tried changing charging port. Cost me a few dollars but no solution.
- Tried USB debugging on and off from developers menu.
- Did MTP+ADB option in *#*#0808#* menu.
- Turned Low Battery Dump "on" in *#*#0808#* menu.
- Tried 10 or more different original Samsung cables.
- Upgraded PC USB drivers.
None of them worked for me.
Hope you have made a progress.

For those who can't connect with Kies

After half an hour trying I have just found a working solution how to connect your SGS in Kies. Here is the deal:
Start Kies, put phone's USB settings in Kies mode. Connect your phone to the PC. Wait until MTP App show "Connected". Go to your PC's Device manager, find Portable Devices and select Disable on GT-I9000. Do not wait for the disabling process to be completed, just disconnect the USB cable. Now connect the USB cable again, wait the MTP App on the phone to show you the message "Connected" and choose Enable on GT-I9000 in Device Manager. After a few seconds your phone should be ready in Kies
I tried this both on x86 and x64 Windows 7 and it works for me.
I hope this will help! And I hope there isn't another thread with this solution. If there is - I'm sorry
i cant wait to get home and try this... another 10h to go
but if this helps ur a geniues

Will put this in the FAQ if we have some confirmations for its effectiveness
when i first bought my phone it worked with kies, but after flashing it to a different firmware there was nothing i could do to get it to connect. i had deleted drivers, re-installed, etc etc but nothing worked. what ended up working was putting the phone in download mode, plugging in the usb to both phone and pc, then putting the phone into recovery mode, and as soon as the recovery menu popped up my device was recognized and the correct drivers were reinstalled and all was fine again

If you still have this problem, please try my method and tell me if it works
I had issues and I also tried this method. But it didn't help
Last thing I tried was to format the internal SD. That did the trick for me....
The biggest problem with getting the phone to connect to Kies is two fold:
1) MTP application will ONLY launch from the home screen (touchwiz screen). NOT from any app. drawer / launcher screen
2) If USB mode on the phone is set to Ask on Connection, MTP won't launch due to the USB app. being open (see 1) above)
If you set USB to Kies mode and then ensure you are on the home screen of the phone with nothing else running, Kies WILL connect
Also remember the 16+ size extension bug.
So a full wipe on ur I internal sd card is a good solution just make sure u back it up tour hdd
I also did a "Driver recovery" from Kies and it worked after that. Although MTP driver failed to install for me in this case.
Make sure to update to the latest version of Kies ( Now 1.5.1.0074.45 ) as this version seems far more reliable when connecting the phone
I recently discovered that the culprit of Kies continuously trying to connect to phone was caused by wrong MTP driver selected.
Under WinXP
After phone connected in Kies Mode..Go to Device Manager/Portable device..
If you see a device labeled as "MTP xxx or Portable device.." ,wrong MTP driver or older driver has been used..For my case, a Microsoft 2004 MTP driver was selected.
To fix it.
1) Do a manual driver update..for my case ,i let the driver wizard to search automatically..this round, another newer Microsoft driver was found..in fact 2 of them.. after installing the drivers(Microsoft 2006 MTP driver,2 are listed..). .Now Device Manager/Portable device listed "GT-i9000" ,Kies immediately found my phone.
Driver name that worked are "wpdusb.sys" and "wudfrd.sys" found under \windows\System32\drivers\..

You must not understand English. The entire reason I posted a comment was to share how I overcame this issue, so that would mean I no longer have this issue
Probable Fix for Kies
Friends,
I have also faced the same problem (while connecting my SGS via Kies MTP was crashing). It used to work earlier so I started to remove Applications and data in the reverse order of Installation. After I removed "Dolphin Browser HD" and all saved bookmarks it started working.
This may be a probable solution if you also have Installed Dolphin Browser.

2 different issues.
MTP crashing on phone is independent from Kies on PC cant detect phone.
i couldnt use kies either but i wasnt worried as i hardly have free time now..
this was a simple fix and now it workes perfectly for me.
sorry about the late replay.
thanks
I'm glad that it works for you
try this
try #9 on

You might be interested in my little APK (SGS Toolbox). I first created it to have it read the product code from the nv_data file to allow you to check whether it has been modified after a firmware update. But now I added some extra options, of which one is the option to check whether there are new firmware updates available in KIES by issuing the same request KIES does when checking for new firmware. This way you don't have to connect your phone to your computer all the time to check for new updates in KIES. Note: It sends JM1 as the current firmware version to find the latest. I might send the actual phone's firmware version once I figured out how to find it. See: http://forum.xda-developers.com/showthread.php?t=778244
Thanks, I'll give it a try

A800i USBsettings has stopped

Guys could anyone help me?
My phone is Samsung A8 variant A800i non-rooted and already 6.0.1.
Eversince I upgraded to MM thru ODIN I am encountering an error in my OTG as in it won't read any disk... the only resort to make the otg work again is to reflash my phone. However during the most recent otg failure, a "USBsettings has stopped" was shown. I factory reset my phone but still this notification appears everytime I start my phone. So when I decided to reflash my phone, I was shocked that my laptop only charges my phone. It can't even detect my files thru mtp connection.
I tried the following and my laptop still can't detect my phone:
1. At the Developers Option I tried to switch the USB Configuration from MTP to Charging to MTP and various other switching, while connected and unconnected to laptop.
2. Dialled *#0808# to reset USBsettings but I am only getting "USBsettings" has stopped.
3. I reinstalled the USBsettings.apk from the system folder (via total commander).
4. I have installed USBsettings.apk taken from another phone.
By the way before I tried the above methods I have already eliminated the cable and pc problems since using the same cable and laptop, I can connect my other samsung phone thru mtp and is detected by odin. I have also tried various other desktop on Windows 7 and 10 but still the same problem: these only charges my phone.
Moreover, there is no abnormality in my charging time eversince this happened.
Hope someone could help me make this work again.
Thank You.

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

Honor 8 Lite PRA-LX1 can't connect to PC

Hello there dear XDA users. I have this problem.. 2 weeks ago I connected my phone to the PC to transfer some music. No problem! No HiSuit or any other program needed. Just put the cable on both sides and it works like a charm. So far so good. 2 days ago I wanted to get some more music to my phone. I connected it like I usually do for 100th time and this message popped on my PC screen. "the last device you connected to this computer malfunctioned" I said to myself "ok not big of a deal I will fix it." YES ...but NO. I tried EVERYTHING. Going into Manage:
Uninstalling all USB - Not working
Updating Drivers to all USB - Not working
Disabling all USB - Not working
Uninstalling all hidden USB - Not working.
______
Regedit:
I also tried that ,yes.
Regedit editing - Not working
Power options - Not working
I freaking tried everything but it still not working. Whenever I connect it to PC the message pops.
I downloaded HiSuit... here gets interesting. When I installed HiSuit it connected to the PC !!! BUT. After I disconnected it I wasn't able to connect it again even with HiSuit. I tried to do the steps as I did them when I connected it with HiSuit , not working yet again.
Also tried ALL USB ports on my PC . Tried 3 diffrent cables. Tried phone on different PC , still same error. Tried phones on my PC , no error. They connect like a charm.
Phone Factory Reset - Not working.
The phone is NOT rooted or updated out of stock Huawei 7.0 android.
Also the phone connects to PC and starts charging. I tried debugging and etc. Not working also.
I hate to be this person but.. bump?
