hello! i was searching through the internet and I can't seem to find a definite answer for this type of problem.
my galaxy s4 can't seem to have a stable connection with my PC. it works
so far what I've done
-plugged it directly to the motherboard usb port
-used samsung original cable
-install all USB drivers (installer, kies)
-uninstall, reinstalled drivers but no avail
-used different cables. ( the original cable doesnt seem to work. whenever i plug my device, it only charges. but there is no notificcation that tells me the phone and PC are connected to something) and then i used a motorola cable and the phone and PC seem to detect each other. but only in one of the motherboard ports.
and also, if ever the PC detects my phone, the "connect/disconnect" loop appears... the "connect/disconnect" loop DISAPPEARS when i plugged the phone to a specific port. BUT, it cant seem to have a stable connection. whenever i transfer a large file, lets say a movie. it copies the file half way then the phone suddenly disconnects then reconnects by itself automatically like nothing happened. I couldn't also flash firmwares cuz whenever odin tries to push the files into my phone, suddenly odin will stop and says "disconnected"..... by the way, my PC's usb ports are OK. it can detect and transfer large files from my brother's optimus G and my sister's motorola droid with no problem. I have used this PC for flashing my previous phones with no problem (SGS2, SGS3, SGS1, Gnex, NOTE2, SGmini, china tablets). Yes i do change phone frequently.
can someone please enlighten me on this..and oh! by the way, I tried flashing and transferring files from my gf's laptop and there seem to be no problem at all... I even used the original samsung cable which doesn't work on my PC at home. I would really like to flash my s4 with the latest 4.3 jellybean, and my gf is back in her home town for the sem break so I can't use her laptop for now cuz she has brought it with her..
I would really any comments and insights will be highly appreciated. thank you!

Your phone has a defective usb port, replace it if it has warranty

not really. because it works with my gf's laptop no problem. but thanks for your reply.,
please help
The hint's in your 2nd last post. There's obviously something PC-side going on; your PC - probably with the USB ports, if it works on your GF's PC. Think about it, that's logic. If it was phone-side, it wouldn't work with any PC.
Fix
First connect ur phone to the pc whit the original white cable
them in ur S4 prees the notification of the usb is connected
Enjoy
If u just connect the phone it will only charge. U have to touch the notification.
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!
Hi, background is this..
I have a D802-10C G2 that i rooted the stock 4.2.2 rom a while back using the post chinese method. Easy enough, all worked fine. no complaints. A couple of weeks ago i got offered the OTA 4.4 update, this failed due to the root. I then removed the root using the feature in super su. that seems to have worked as no apps or file managers etc could get root access. However, the OTA still wont work.
Now my problem is my phone will no longer be recognized by any operating system, on multiple computers. I have tried many ADB drivers, Windows 7 wont even detect the device, i've used every PC connect mode, USB debugging. However always the same result, it's as if i'm plugging in a blank usb cable into the computer. Nothing at all.
The only thing that does happen when i connect the phone to a computer is the phone starts to trickle charge. There is nothing detected in Device Manager in Windows 7 I've tried connecting in download mode, nothing. I've tried the LG support tool, PC sync. Nothing.
WiFi does connect to the PC suite fine BTW and other than that the phone is working perfectly. I've also tried connecting multiple usb cables on multiple ports.
I haven't been able to find a single case of the same problem in the week or so i've been looking. Hoping someone can help, i'm thinking i may have soft bricked my phone. I really do not think this is a driver issue.
Any help would be great. cheers

YOu can try checking the device manager or use other USB port on your phone.

The problem is not like the usual ones you will see about "computer not being able to see device" I don't think it's a driver or software issue, or if it is it's unlike any i have found in the weeks i've been searching the net for a solution. Here's why....
When i connect the phone to Windows 7 and 8 ( on 3 different computers) No hardware is detected, nothing in the Device Manager, no yellow question marks indicating 'Unknown Hardware'. Nothing, all it does is start trickle charging.
Now even with no ADB, or any driver at all installed, the computer should still detect the phone. Mine does not.
The same thing happens using OSX and Linux Mint 16 (again multiple computers) No devices or mounted or volumes shown at all. Linux terminal command "$ lsusb" does not list my hardware.
This is why i'm pretty much convinced that there is something wrong with the USB port on the phone. Because, if Linux can't see it then surely it's a hardware problem right?
The only other thing i can think of is, i have messed up the phones firmware while trying to unroot it? but only because the timing of all this is just too uncanny.
I think i'll have to suck it up and admit defeat here. Funny thing is the phone works perfectly and charges fine.
Stuck on 4.2 , with no ADB functionality. Perhaps i'll sell it cheap to someone who doesn't care.
Cheers for the reply mate.
Same problem here!
Only my G2 is not rooted, it is still on factory OS and recently updated to 4.4.2.
I have tried on several computers, different ports and no help.
On the first connection to a PC not connected before windows reports "USB device not recognized" problem.
After that every time I connect the phone to the same computer the phone itself only recognizes that it is using USB charging mode, it does not recognize the computer connection (known by the USB ison on android system tray) even with "Ask upon connection option checked".
Even when I manualy change the Android mode in Settings --> PC Connection from MTP to PTP or even LG software, nothing happens.
Definetly there seems to be a problem with the phone, but I don't beleive it's a software but a firmware problem.
Please help if anyone knows what to do.
same thing happened after installing T-mobile rom thrugh twrp. but my device boots into fastboot and i tryed falshing :
laf.img, boot.img, aboot.img, recovery.img, laf.img
but after reboot my LS980 dissapear from device manager and stucked on LG logo.
Dont know what to do now.
I'm no expert, but given there are a lot of them here and none have weighed in on this with any ideas for a fix, i'm going to assume it's a hardware problem.
Anyone else agree? Hardware problem not software?
Cheers
I guess that you already wiped everything right? Apart from that, i'll suggest you to go to some tech supp and ask them if they can verify that each pin of the micro usb is properly working.
Sorry for my english, hope it helps!

I will try to check the connector although i dont think that it is a hardware issue.
BTW I can enter the download mode after flashing the mentioned partitions and i can also enter the stock LG recovery but when i do the factory reset it keeps showing Factory reset processing ... for ever
It has happened to me the same thing :crying:, and is a problem with the boot.img, if by chance your G2 version 4.4.2 and the the 4.2.2 boot.img, goodbye.
The only solution is to take it to repair a service official, there will change you the card, with the consequent change of IMEI.quent change of IMEI.

Sirs, I flashed the baseband (https://www.androidfilehost.com/?w=files&flid=12880) then it got working back.
solved for me
I have some kinds of that problem, let try:
Settings -> General -> PC Connection -> Select USB connection method -> Media device (MTP) (or whatever)
Got this same issue after flashing cloudy g3 rom. Then later flashing dirty unicorns, which requires jelly bean baseband. But even restoring g3 and 24a baseband, still doesn't work. No pc tethering and no on the go usb. My usb port is basically charge only.
---------- Post added at 03:58 PM ---------- Previous post was at 03:56 PM ----------
Everything else works fine...I actually never even noticed this bc I never tether to pc. But now I have to bc I want flask kdz
Help me please

Anyone has an idea how to fix this problem?
same problem
I have a LG G2 . recently updated from vs98027a to vs98039a 5.0 lollipop. Since the update my computer won't recognize my device in download mode and I don't have superuser ppermissions. Help plz
I also have the same problem.
It happened when I tried to backup info through LG PC Suite: the phone disconnected during the process, and now it's not recognized by any PC (http://forum.xda-developers.com/lg-g2/help/lg-g2-recognized-windows-backup-t3155323).
Also found a description of the same problem here: https://www.reddit.com/r/lgg2/comments/2urpnw/lg_g2_usb_only_charging_not_recognized_by_pc/ - no solutions, too.
Did anyone manage to fix this?
Hello everyone,
I own the samsung galaxy note 10.1 edition 2014 and for some years now I have not been able to use it properly. When I put the tablet to charge, I have a red cross on the battery. Following much research, no proposals have allowed to fix the problem. I notably changed the battery, the charging port as well as the cable and the charger (while all the original components seem to work).
On one of the forums, I read that changing the rom and updating it on lineage on android 7 could have solved the problem. It also suited me because many applications that I use every day no longer work on the tablet.
So I try to root the tablet but once again a problem arises, odin cannot find the tablet in download mode. So I look at the device manager and I see that indeed on the usb port there is registered device descriptor request failed. So I go back to the forums, I try again a multitude of soultions that do not work as installed, uninstalled, reinstalled the drivers. Make manipulations in windows. Change USB port, cable. Activate debug mode or not. I even put the old charging port back. Nothing to do I always have the same message.
I also thought to myself that it was because I can't choose MTP mode on the tablet, I tried to do some research, I couldn't find anything conclusive.
So I'm in dire straits, I'm waiting for my savior :crying:
Thank's in advance for answers
Sincerelly
Ps: My tablet is in kitkat version and I cannot switch it to the lolipop version because I have a message telling me that the tablet has been modified.
Hi,
I tried flashing the new v11 firmware via Odin. Unfortunately, i didnt work (i come from v10). Now i get that error message , that i´d have to use Smart Switch soft on PC to do an emergency recovery. Unfortunately it seems to find it (some usb plug in sounds appears in windows) but the device can´t be found. Whats the take here ?
The USB drivers seem to be installed fine. Thanks in advantage!
