[Q] Cannot connect to PC with USB!

Hello everybody,
last friday I plugged in my Galaxy S4 (i9500, rooted) with my usb cable to my PC, everything was fine. I shut off my computer, went on a holiday for weekend, used the cable with my laptop and my friends' laptops everything was fine. Now I came back home, opened my PC, plugged in my phone, it only charges! I cannot access to my files and stuff via neither My Computer or Kies. It only charges.
My computer uses Windows 7 x64, everything up to date, tried to uninstall Kies, Samsung USB driver, none worked. I tried using diffrent cables, usb ports too. Diffrent computers, no problem. My Pc, only charges
The thing is when I look into my pc's device manager it says "PCI Input Device". When I first plugged in today and it didn't worked it said "Android Composite ADB Interface"
Both had yellow exclamation mark on their symbols. I tried removing them, restarting pc and swiching users, none helped.
Any Ideas?
Thanks..

Problem solved
I removed all the drivers, put my device to download mode and plugged in, worked very well.....

[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.

When you dial ##366633# is it disabled?

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!

[Q] Nexus 4 gone stealth

... and is no longer recognized when connected to a computer via USB, meaning I can't return to stock to get ready for the Lollipop OTA.
Got a rooted Nexus 4 running the latest PA beta.
What happens when connecting to PC:
- On two different Windows machines: systray popup saying "USB device not recognized. The last USB device you connected to this computer malfunctioned etc.". In device manager it says "Unknown USB device (device descriptor request failed)"
- On elementary OS, based on Ubuntu 12.04: nothing, besides charging.
No USB debugging connection notification on the Nexus 4 either when plugging in.
What I've tried (USB debugging enabled, all relevant drivers installed):
- Settings > Storage > USB computer connection > check Camera PTP (used to be required in order to get an RSA key prompt when connecting to a computer, now it does nothing)
- Flashing latest stable CM to see if PA was to blame. Made no difference.
- Uninstalling device through device manager in Windows and reconnecting. No effect. Driver update doesn't work either, finds nothing.
- Using Wugfresh's Nexus toolkit to see if that worked, but that obviously doesn't work either when the device isn't recognized, same with the Universal Nexus Linux Toolkit on Linux.
- Scouring the net for solutions and coming up with nothing
I have flashed factory images before on this phone without problems. Should I consider it a hardware failure by now, or is this a known issue with a fix?

Try a new wire, different usb port on computer, finally look into cleaning your charging port on the phone/replacing it.

Tried three different cables, every port on two laptops, no joy - my girlfriend's phone connects normally.
Wouldn't replace the charging port, then I'd just get a new phone since it's a 2 years old Nexus 4. If only there was a way to flash the factory image using only TWRP.

Flash this in twrp http://forum.xda-developers.com/showthread.php?p=47476426

Thanks jd1639, that seemed to be exactly what I was looking for -
- but then I had an extremely blonde moment and formatted everything in TWRP, wiping the ROM I was gonna flash in the process, on a device where USB file transfer doesn't work anymore
My phone is now a paper weight.

Have you tried the file manager in twrp yet? I've found it connects when nothing else will...

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
