My phone just won't connect to my PC - T-Mobile, Samsung Galaxy SIII

I'm running 4.1.1 and every time I plug my device in (With stock USB) I get "USB device not recognized"
I've tried another USB. I've downloaded Kies (Will only connect wifi), I've tried reinstalling drivers, I've tried using another computer as well. I've also enabled/disabled USB debugging,
The USB connection notification only appears sometimes, and even when it does my computer still won't recognize my S3. After I reinstall the drivers my phone does say "Connected as a Media device", but then the notification goes away..
FYI, I'm trying to root, that's why I need a direct connection with my computer so badly.

Does your computer has samsung kies?
You say drivers. Idk what u mean but all we need is samsung kies.

I tried your method a few days ago, and it didn't work. I tried your method again.. it doesn't work.

I had this issue. All I did was get some good ol canned air and blew the dust out of my micro usb port. After that it connects just fine. Was about to do a warranty exchange before I did this.

Tried that as well. Neither computer works. Blew into the phone as well ...

Its your rom on the phone that's causing this. If you want to rule it out, why don't you just do a nandroid backup and install stock rom or perhaps the same rom clean from start. I had this issue before and it was fixed with reflashing clean rom.

I should probably mention the phone charges will of the USB cables but none of them work with the PC. I can't tell if it's a software issue or internal..

I think it's a computer issue, what was the other computer software you tried on?

Tried it with W7 & Mac, neither recognize the device. Android file transfer just tells me "no device found", and the Kies on mac doesn't work either.

I still won't update my computer from XP cause all I read are device errors with upgraded versions of windows... see if you can get your hands on XP and try. Just as insurance, you have gone through device manager and removed all drivers for the phone and then pushed the proper ones from Samsung, correct?

watch the screen closely when you connect the phone to the pc. does it even recognize thst some usb device was plugged in?
After a few moments, (with the phone still connected) click start,right click on my computer, select manage and select device manager.
are there any yellow question marks on the right side under the computer?
Open the modems (click the + sign) is there any SAMSUNG USB Modem? (should have no yellow question mark)
Open Universal Serial Bus controllers, do you see the samsung Mobile USB Composite Device?
There should be NO yellow question marks or exclamation marks anywhere on the right panel.
If there are, there is a problem with your computer settings/drivers or services.
If you followed my "cannot fail" steps EXACTLY in the order I had it, and did not skip anything, you should be without any problems with the modem connectivity. That includes the uninstallation of any samsung drivers previously installed.
If you do not even see the samsung modem, the cables or the phone may be your problem.
Post your results and I'll help you to get it working. Also mention what your compurter's OS is.

My bad, speed reading is not always good... thanks for pointing that out.
Anyway, did the OP ever get this resolved? Bobolinko's steps are thorough and if that didn't fix it, why don't you just try to go into download mode and ODIN a stock ROM with root injected into it already? It's another option...

Did you try buying a fresh new cable to connect the phone to the computer? I only have those issues with corrupted USB cable and a messy laptop...
Also when that notification appears for me I go to my phone USB section and tells it to mount as storage...and if its on storage I switch media than back to storage...always work for me.

As soon as I plug my S3 in, my computer recognizes a USB is active. In Device Manager, I do not have Samsung USB, all I have is "Unknown Device". I'm not sure what you mean by yellow exclamation point in the bottom right, but there's nothing in my notifications. However, I do get 2 yellow exclamations in device manager. One in Universal Series Bus, and one in other devices

Hi there.
Check this
On calls hit *#7284#
Check if pda is enabled then click on qualcomm settings and see if mtb+adb are enabled.
If not then just enable those.
Hope this is your problem.
Good luck.

I've tried this as well. I get this error:
"Connection problem or invalid MMI code"

The problem is with your computer, and not the phone. You CANNOT get it connected with a problem in the USB settings.
click on the yellow exclamation items and DELETE or UNINSTALL them. then reboot the machine and it should reinstall automatically. If your DRIVERS that are already in the machine are bad, you have to get them updated or replaced. uninstall KIES from the computer, reboot, and reinstall it. go to samsung's site and download and install the driver for your comuter.
The one for the xp is: SAMSUNG_USB_Driver_for_Mobile_Phones_1.4.8.0.exe
install it to your computer and be SURE there is no error while it installs.
then check again your device manager list for any yellow problem areas
connect the phone and wait a while, then, disconnect and wait about a minute
then again, connect the phone, and wait at least one minute. open the device manager page and see if there are any yellow area problems again.
are you positive you have the latest window updates?
you can sometimes right click on an item and do the driver update and fix a problem.
You clear all the COMPUTER END PROBLEMS you have and the phone will connect. That, my friend, you can take to the bank.
Good Luck!
Aloha,
post your results later

Device not recognized

"USB Device Not Recognized"
I have searched for so long trying to figure out what's wrong. I'm out of idea's on how to fix it, nothing will recognize my Evo.
Tried on 4 different computers, two of them running 7, one running xp, and last running vista, all say the same thing, computers not the problem.
Downloaded htc sync, disabled/enabled usb debugging, restarted the phone many times, restarted computers, and even changed the default usb connection to HDD and HTC sync.
I rooted using the idiot proof guide and used the Sprint Rom he linked in the guide. Would love some help. Thanks!
Try downloading the auto sync app in market
And let me know what happens.

Just tried that and still not recognizing it.
Which HTC Sync did you try? I think the latest is 2.0.40
http://www.htc.com/us/support/evo-sprint/downloads/
set the EVO connection type to HTC SYNC and USB DEBUGGING ENABLED.
Assuming you've used ADB, what response you you get from
ADB DEVICES at the command prompt?
you should get something like
C:\>adb devices
adb server is out of date
* daemon started successfully *
List of devices attached
HT05EHL10353 device
and we will know you have a good physical connection to the computers. If it doesnt show up, try a different USB cable....

Thanks for the help! I checked for my device in ADB and it does not list it, so i guess my cable is probably bad. I'll go out and buy another and hopefully that fixes the problem.

When i connect my phone in recovery mode, it still just says device not recognized, so i can't really do that.
Sorry but bump, i relly need help with this.
It still says unknown device when i try to connect my phone in recovery mode.
Go into your computers device manager and uninstall the device and htc sync, then reinstall sync and make sure usb debugging is on then plug it in
Edit: sorry, go into the device manager with it plugged in. if its not there (should be a yellow or red triangle next to it or neat the to as a HID) them it could be your cable or phones port.

I think you need to pay closer attention to the guide, because this statement makes no sense in reference to the guide.
The guide is helping you install ADB drivers, you don't need to do anything in ADB while your phone is in recovery in that guide.
Could be wrong, but I'm still fairly certain that the guide will fix your issue, because I had the same problem.
It's as simple as you do not have the correct, or any ADB drivers, therefore your phone is not showing up as a device under ADB. Once you have the proper drivers installed, your device will show up.

I followed the simple guide step by step.
When i boot into recovery mode i end up with this in the picture.
His recovery mode shows an Evo with a little exclamation mark next to it, i'm guessing what i got is still recovery mode. But still if i plug my phone in my computer still says unknown device, so i can't install ADB drivers.

You just have a different recovery. Once you are in recovery, you don't need to do anything else on your phone specifically.
Instead, connect your phone to your PC via USB if it isn't already and open up device manager on your PC and follow the rest of the guide.
Edit: Where does it say unknown device? In Device Manager?

It shows up in usb controllers instead of other devices as he shows in the guide. If i try to update the driver it just tells me it's already up to date.
>Sorry yea it does say unknown device in device manager.
Gotta bump, would really love to just fix this instead of driving 30 mins to a sprint store.
So i followed the guide for installing apb drivers, but even in recovery mode my phone still shows up as unknown device in device manager.
Ok, well I just ran into this myself on my secondary computer. Have you tried a different USB port on your PC?
My front ones were giving me unknown device, but as soon as I plugged it into one of the ports on the back of the mobo ADB showed right up in device manager.
Factory reset it and get it exchanged.I belief is the SD card failure issue.

I have the same problem and posted this question on 3 forums including the HTC support forum and nobody has been able to find the correct solution.
I know the cable and the port is good because I can connect my Samsung Moment to it and it works perfectly. On the Evo, I've downloaded the latest HTC Sync from the official HTC site, tried the one on the microsd card, checked and un-checked USB debugging, and still it doesn't connect.
The Evo won't connect to my Win 7 computer at home, Win XP at work, but it will connect to my daughters computer which is running Win XP also (all 32 bit).
I bought this Evo from Best Buy exactly 28 days ago today. Do they give you 30 days to return it, or is that only the Sprint store?
They do give u 30 day trial.go get it exchanged or...........

Help!! USB connection not recognized...

I connected my SG2 via USB cable to my PC and started seeing this error
"One of the USB devices attached to this computer has malfunctioned and Windows does not recognize it. For assistance in solving this problem, click this message."
I have tried everything from changing cables/PCs/enabling/disabling USB debugging to *#7284#, and none of them work ...
Is the device bricked, is there any hope of revival..please help i got this phone myself paying $400
Does your phone turn on and work and a connection to PC the only problem? If so your not bricked...you prolly need to install the drivers in order for your PC to recognize it so install kies on your PC

As I said previously you probably need to add the drivers on your PC install kies on your PC

Make sure you use one of your rear usb ports also. I had an issue with drivers installing in a front usb port.
Phew it turns out to be the samsung driver..I believe kies update must have corrupted and stopped the pc from recognizing the phone....

The definition of "bricked" is having a really expensive
... brick. It means your phone doesn't turn on no matter what you do to it (short of a JIG and that's not guaranteed) the "USB device not recognized thing" is a problem w many windows devices my vista computer does it all the time and I just switch ports.

Having same/similar issue
Hey, was there every a solution found for this?
I'm having basically the same problem...using the cable that came with my phone, and have installed Kies (fresh). I have tried toggling multiple settings. I tried uninstalling kies and reinstalling. I tried using pdanet for the driver. I have tried a few different roms, as well: Darkside 2.4, 2.5.1, and gingersnap 1.21. All have had the same result.
When I plug the phone in, it beeps (charging) but no notification for usb settings (disk drive, sync, etc). On my computer, it pops up "USB Device Not Recognized" and says the device has malfunctioned, etc, same as OP.
In Device Manager, it shows under USB as "Unknown Device".
I have tried this with two Windows 7 laptops, and a Windows Server 2008 R2 desktop. Also tried with a different cable. This cable was able to transfer data from an external hard drive today, so I doubt anything is wrong with it.
Any help is greatly appreciated!

Did you try the drivers separate first or Mtp mode
Sent from my revolutionized Samsung infuse
I tried without the drivers, and went to wireless and network > USB utilities. The only option in there, however, is "Connect storage to PC". If I try that, then plug it in, the phone acts like I hit the back/undo button. It doesn't show that anything is connected, nor does it give any other options. At this point on the computer, I get the "USB device not recognized" error.
This happened before installing Kies/Drivers, and still happens after installing drivers and kies.
try another usb cable
i had the exact same error, and it ended up being a good USB cable that went south
I will try a different cable when I get home - Have a month old cable for a mytouch 4g that I know works.
Okay, I tried it with the other cable, on a desktop in the rear port. same thing...Phone start to charge, and I get the error that the device malfunctioned, yada yada.
Any other ideas? Should I try to connect in Download mode?
Alrighty, so in the end, I ended up completely unroting, using terminal emulator to remove superuser.apk, busybox, and su and putting right back to read only. Then in CWM, flashed a stock 2.3.5 ROM (Zedomax). However, I now have the 2.3.5 ROM and the 2.3.6 KL1 Kernel...
I'm planning to return to Tmobile/Samsung - will the kernel and rom versions not matching be a huge red flag??
Any help is appreciated. I have tried to flash the 2.3.5 kernel, but I always get an error that it's not signed/verified.
Ideas?
I was hoping to grab the 2.3.6 OTA update, but it says there is no firmware update. Is there an update file I can put on the SD card and update using the stock recovery?
UPDATE:
I called T-Mobile Customer Service today, and went through the "troubleshooting" with them again. They ended up sending me a new one, overnight. They didn't ask anything about doing anything custom with it like rooting or other modifications.
I'm not sure if it made a difference, but I'm within 90 days, and also have the "best" insurance/warranty coverage through T-Mobile, and whoever their insurance provider is that I signed up for when I bought the phone.
Final charge is for $5, which I was told is some kind of fee from Samsung, but will appear on my bill.
Anyway, not too bad. Can't wait to get rid of touchwiz again when I get the new phone!

FYI, I just went through the same thing. Decided to finally root my phone after owning it for 2 weeks.
Phone nor the phone would recognize USB data, but would charge. Tried another cable and no luck.
Rebooted the phone. Works like a charm now.

flashed ICS rom now phone cant be recognized by computer

ok basically phone wont go into mass storage mode when connected to computer and it isnt recognized by odin or the the computer at all and let me get all these out of the way before im asked
ok first yes driver are installed properly i even installed kies twice and just the drivers from the samsung website to make sure i wasnt messing up somewhere
and then...
i also tried doing a nandroid of blazer rom and getting back to the gingerbread just so my phone would be recognized that also did not work
and then..
i just now bought the mobile odin app and tried flashing the stock eko2 kernel this did not work either
and then...
ive used the original USB cord and the one i bought to day as well as several different computers just to see if the pop up as recognized with show but nothing happens my phone seems like its no longer capable of going into mass storage mode
and then...
moved this here hoping someone has has this issue hopefully you guys can help ill be up all night so feel free to resond whenever thanks guys
make sure your phone is disconnected from the computer and then try going into the settings and in the top section that is wireless and networks press more, then USB utilities, and press connect storage to PC and then plug your phone into the computer. had about the same problem and came across that.
You can also try going into your device settings on your pc (samsung/modem) and resetting the driver it seems to get "stuck" sometimes.

+1 to this... its the new way to connect
I put this on my sd card (by taking the card out of the phone) and putting it in a card reader. I flashed the file from the stock recovery and this gave me custom recovery. Then I restored my previous backup. I was having the same issue and FB21 has too many bugs. I went back to gingerbread but kept fb21 modem.

[Q] USB not recognised

Hi all,
I've read a lot of forums on what seems to be a pretty common issue, however, with each attempt at a fix the answer is still elusive.
the problem i'm experiencing is that when I connect my (unrooted) Galaxy S2 to my pc (running windows 7) the USB device is not recognised. The phone says that it is connected (USB Connect MTP-Connected), however, when I try to access my phone via Kies or explorer it is not there. I also get an error message saying that the 'device is not recognised'.
I've taken the following actions:
- Reinstalled a fresh version of Kies
- Reinstalled samsung drivers (once prompted by Kies)
- Tried at least 3 USB cables including the original Samsung cable
- As per one of the blogs i read, i switched to USB debugging on and then off as there was no effect
- I've tried turning on bluetooth, then connecting the USB device (also a 'fix' i've seen on another forum)
- I've restarted my phone a number of times
- Connected via different USB ports
- Restarted my PC
Could anyone please help me.
Thanks,
Rob

Uninstall all drivers, and Kies.
Restart the computer.
No go to device Manager under Human Interface Device/Universal Serial Bus controllers and see if there is that little yellow triangle there. If so click and uninstall any device with the aforementioned icon.
Now reset again.
Go to the Samsung website and download the drivers for the phone. Restart the computer yet again. Almost done.
Now attach your phone and it should be identified.
Go ahead and install Samsung Kies and you should be ok. I hope all this works.
I had a very similar issue with my last SII. One day it just simply would not be recognized by many computers using various USB cords including the OEM one. Windows always said something along the lines of " USB device not recognized, a device connected to this computer has malfunctioned." The computer would pick it up bit was listed as an unknown device in the device manager. Turns out it was a hardware failure so I had so get a warranty replacement

Not very helpful answers... you may have sorted this out already but...
One solution found on other threads that worked for me was this:
uninstall Kies
key in the dialer *#7284#
it has 4 option there..
UART (MODEM/PDA)
USB (MODEM/PDA)
Only change the USB setting.
Select PDA, if it already selected, select MODEM, don't hit "back", try reconnect, wait for windows to respond.
Unplug, then select PDA, try reconnect.

Try changing your usb cable. If that still doesnt help, try it on another pc. If still not, then send it to samsung for repair.

[SOLVED] Phone Not Recognized by Computer

Hello everyone. My E4GT is unable to connect my computer after I install the drivers. I tried reinstalling them, used different usb ports, and different cables to find out that it still wouldn't work. The weird think is when I connect my phone to another computer after installing the drivers, it works. I'm hoping that someone knows of a fix to this.
OS: Windows XP SP3 32-bit
Edit: I solved this problem. What the problem was that I was missing usb.inf in WINDOWS/INF . To get this file, I got it from the other computer. At the time of me doing this, my only goal was to fix my webcam because I was getting an error about a missing .inf file.

Is your computer a "company" computer? Friend of mine had the same issue due to security settings on the laptop.

Try downloading the kies , sp?, program for your PC, it installs Samsung drivers and may solve the issue

SP3 means Service Pack 3.
Kies did not solve my issue. Thanks for your help so far.

Looks like you tried different USB cables (hopefully NEW ones), and different ports too. Along with Kies.
Try going into device manager (check show hidden devices too!) and uninstall ANY Samsung drivers or software you have installed. And reboot.
Download and install the latest drivers for the Epic 4GT [ http://org.downloadcenter.samsung.c...342248/Sprint_d710_USB_Driver_v1_3_2360_0.exe ]
Reboot your system. Then try to connect again.
If you have some type of Antivirus/Antispyware application you may also want to try and temporarily disable it too. I've seen this happen before.

I'm pretty sure it is not my antivirus because the other computer has the exact same antivirus. Also, in Device Manager, I enabled hidden devices and I do not see any drivers that seem like they have to do with Samsung.
Cool, but did you uninstall, reboot and then reinstall? And did you also disable the AV just in case?

Uninstalling Kies right now. I will post after I reboot my computer.
I rebooted my computer, installed the drivers, and it still did not work. It's like my computer does not know how to use the drivers for my phone.

Wow not sure what else to try. If you've tried removing all drivers and re-installing them, using brand new USB cable(s), using different USB ports and disabling AV software and if it does connect and show up on other PCs yet it still wont show on one PC, then something is amiss with that machine.
When you're connecting your device you do have it on too right? I'm sure you do but just checking.
Did you install any ROM on this device already? There are some international versions that if installed on this device disable the USB port.
And does it show up on other machines just not this one?
If it shows up on other machines than it there is something amok with that PC.
If it doesn't then..
One last thing you might want to attempt is to download sfhub's One-click FF18 http://forum.xda-developers.com/showthread.php?t=1721229 download the 'reset data' and extract the exe.
Make sure you phone is off and NOT attached to the PC.
Run the One-click application.
Simultaneously Press and Hold [Power] [VolDn] until confirmation screen appears
Press [VolUp] to enter Download mode
Then Attach your phone via USB to the PC and see if it shows up on a COM Port (anyone is OK).
IF it does you can then at least flash the stock rooted FF18 and get the device to probably work correctly next time you plug it in after of course the entire Odin/Update finishes and your phone restarts.
Just reaching here but hope that helps.

This shows up on other computers but not this one. I did install CM9 onto my phone, but when I was on stock, this problem was still happening. This is most likely something with this PC. Thanks for you help.
Well then that's it. PC is the issue it won't show. Something is pooped.
Good luck.
Just to be clear, when someone says, 'try different usb ports' make sure you only use the ports on the motherboard and not the ones on the front of the case or door.
It's the difference between powered and un powered.
That one the threw me for a loop on my win7 when I usually use my laptop with xp.
