Since upgrading the Galaxy S to 2.2.1 which I absolutely love - must faster than anything previous, sleek, really well done, I've just noticed for the first time that my USB doesn't seem to work.
The computer sometimes sees it but just says the device is malfunctioning, the phone sometimes sees the PC and gives a menu for "ask on connection", but Windows just does not know what this device is at all.
Suspect I may have to reinstall the drivers fully in Windows, remove it completely and try again, if it actually showed up as an unknown device in Device Manager.
I do need to try another PC and cable just in case, but this is what Im having at the moment in Windows:
USB Device Not Recognized
One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it.

And the Phone is currently not detecting any connection.
Any thoughts?

I would go with a windows problem and remove the usb drivers/Kies .
Followed by fresh install .

You can find a link to the usb drivers in my signature.
I think its a little more problematic.
I've tried another computer, another OS and another cable no joy.
I've installed aLogCat and Im getting:
Intent Action android.intent.action.ACTION_POWER_CONNECTED
Battery charging.plugType = 1
AC Charge
In MtpReceiverandroid.intent.action.ACTION_POWER_CONNECTED
Battery charging.plugType = 1
Not of USB charging. Dont lauch MTP APP

I've done a quick search on this. Hopefully this is as simple as doing a factory reset and format the internal sd.
If not, then Im off to a samsung service centre I think.
Any further thoughts?
:-(
Factory reset the phone, but the USB port still is not working. Charges fine, but don't connect over USB to the PC.
Can it be in debugging mode. Try to switch between mass storage and kies.
Probably you have checked that already..

the same problem from me i tried all but the usb is not working at all. I flashed kernel , i flashed rom but nothing .
Now i am looking to install untouched rom in order to give it to service but when i am trying to flash from recovery i get an error . Any suggestions?
This may sound dumb, but it could be the USB port acting up (loose connection). Try wriggling the cable around or use a different port.

Right, I've tried all available USB ports, two different computers, two different OS's. The phone just does not register a USB data connection. It only recognises AC charging according to the logs.
I think I have a broken USB port on the phone as if I jam the connector in at an angle on the phone, it sometimes registers the data connection but its far too unreliable.
Development mode don't work, Kies, Mass Storage etc... anything. Nothing works.
Factory reset doesn't make it work.
I can't even flash a new ROM as the phone is not detected in download mode.
I've got the phone booked in at a Samsung Service Centre now. I've seen a few webpages referencing corrosion. I tell you what though, this phone has been protected way way more than my old N97. I've had so many phones and not one has suffered from "corrosion". So let them just try and say it's my fault. Im ready for em.

Try cleaning your phone usb port. A guy named omersak had the same problem, and he had solved it. Search for the thread started by him, and how he has solved it.
I hope you can solve it without going to the service centre. And good luck.

Definitely trying that first - thank you to all the people that have been doing the investigation.
It sounds to me like Samsung have got a bad batch of USB connectors that should be replaced under a factory recall.
I don't use mine in a shower, or sauna, or anything like that, I don't even use it in the rain.
The closest it gets to any humidity is being in my shirt pocket from time to time.
Im going to get some meths or something like that and some thin paper and see what I can do with that. Im just off to Homebase!
there are similar problems on the galaxy 3 series where usb suddenly stops working. the following solutions seem to work there:
1. dial *#7284# to open "PhoneUtil"
2. in USB section, switch to modem, and then switch back to PDA
if that doesn't work: reboot into recovery and select "wipe cache partition"
*hth*
I've tried both of those before I start splashing the methylated spirit around. Still no joy.
Wipe Cache don't work, as well as wipe data/format sd/restore factory defaults etc.
I think I've got a 100% hardware fault.
@OP,
I am terribly sorry about your case. Looks like you need to make that trip to the service centre.
At least you have tried out every possible means known.

Also tried the meths. No good. :-(
The USB just started working yesterday. Still a bit intermittent, but when it gets a connection, it maintains a connection.
I've just ordered some isopropyl and a gold plated USB connector to be on the safe side
Hi everyone,
To sdjean: maybe you could read the post I sent a few minutes ago:

It might explain why your usb data connection does not always work ...
Regards.
I have a Samsung GT-I9000B and I cant use it using USB.
I have 2 usb cables, I am able to find my friends phones.
Now I cant change rom cause odin cant find it too.
Alog cat shows:
E/MTPRx ( 4020 ) Battery charging. plugType = 1
E/MTPRx ( 4020 ) Not of USB charging. DOnt launch MTP APP
Any suggestion?
I'm not an Expert but 2 hints from me:
1. If you have'nt tried yet: Install usb-drivers on pc new and then connect your phone and wait until drivers are installed to your phone.
One times this way worked on my i9000.
2. Look for a zipped rom on xda which you can directly download and install from sd-card.
Sorry, I know my English is bad.

I cannot get my epic to mount for ANYTHING! I factory wiped the phone, nope, I used a palm pre usb cable nope, I downloaded the official samsung drivers nope, I plugged the cable into the motherboard on the computer nope, I tried a different computer running windows 7, nope tried a laptop using windows vista, nope. Does anyone know ANY WAY POSSIBLE to get this thing to mount? I selected mass storage and dissabled and enabled usb debugging. Im just not having any luck. It seems that the computer recognizes the phone is connected just cant get to the files on the SD card.
I also spent many hours trying to figure out what the hell was wrong with my Epic, that is, why it would come up as a "malfunction" in Windows when I plugged the USB cable in.
I tried drivers, different restore points, wiping, etc. etc. etc.
To the point... Try a new USB cable. The one packaged with the Epic is junk. As a matter of fact, it worked several times before it crapped out. I have no idea why, but I picked up a new micro USB cable, plugged it in, and the phone was then immediately recognized by my computer to allow mass storage mount.
People who tried the Palm Pre USB cable also had issues for some reason.
IMO, there should be a sticky posted in this board regarding the packaged USB cable, as I encounter this issue quite a bit.
Ok I'll try to find a new one really quick thanks
ugh tried an HTC Mytouch 4g usb cable and that didnt work either. Gonna try a class 4 usb stick and im gonna try puttting all of the files on the computer from the SD card
Edit: Oh wow i cant put the files on the computer duh
Edit: Ok now I'm mad a Class 4 SD card wont connect to the computer thru the epic ughhhh
I'm guessing during this time, you've rebooted the computer a few times? Sometimes, that's all it takes...
Try uninstalling ALL of the USB drivers associated with the Epic, rebooting the computer, then connecting (with debug mode OFF). Windows found and installed the USB drivers for me in just a few seconds when I did this [with the new cable, the first time].
- G
Have u enabled development mode under settings > applications (in your) epic? If not, try that, then plug in cable.
Then pull down the notification bar and it'll give you back the option.. again, if you haven't tried this.
On occasion I have troubles with the Epic mounting/ejecting on a Mac, but the only time I've ever had an issue with it mounting on a PC a different cable solved the problem immediately.
Try a different USB port on your PC. If that doesn't work, try rebooting the PC and the phone.
I had luck with trying different usb ports though
I had this problem as well and:
1. Tried 4 different cables
2. Tried all 4 on all 4 different USB ports
3. Rebooted numerous times
4. Uninstalled/reinstalled drivers
5. Tried 3 different PCs (1 other running 7 and another running Vista)
6. Did 1-4 on all three computers.
OH! and the reason I was so adamant about finding a solution was that I was stuck in Clockwork... due to having messed up an EXT4/RFS/CW2.5/CW3.0 installation... It was MY fault... I screwed up.
The problem was I had been living with the nonmounting problem by simply putting my MicroSD into an adapter and plugging it into my Laptop for file transfers... never expecting to HAVE to ODIN at some time...
Anyway... I ended up coughing up the $100 to Insurance and replacing the phone.
HERE IS MY THEORY: I think what my problem was was that the USB port on the Phone was messed up. I think these USB ports are possibly a hardware fail point and the changing of cables has been a patch on the issue with the port... NOT the cables themselves!
I'm not suggesting that you are there yet since it sounds like you can at least still get the phone to boot up (and aren't stuck in CW) and could still use a work around of putting files on the MicroSD with an adapter...
But I would suggest you don't be as stupid as me and get yourself in a position where ODIN is your only hope.
Yeah, it sounded like a bad USB port to me. Also, FYIY, if you ever have to replace the phone through insurance, tell them that the phone was lost. Either way, it will cost you $100.00 to get a replacement and when it's reported as lost, they will also send you a new battery...

Did you end up doing an ODIN restore
I have a Samsung Epic 4g rooted with the one click 2.5 and I upgraded to Froyo.
I had to use my wifes phone to copy the update.zip to my sd card because my computer would not let me see my epic. Same computer, cable and model phone works fine for my wifes.
I need to reinstall the one click root and can not get my computer to see my phone.
Is there a way I can root on the phone without using the computer.
So close to done, but I can not use the wifi tether without re-root
Different phones can be more finicky. No valid explanation why though.
Make sure you plug the cable into the phone first, then the computer. Try using different USB ports. If all else fails, try another cable.
I have seen a bad port on the phone before, but it had charging issues as well.

I have tried all the ports on my laptop. The phone acts like it is connecting. Even brings up the new usb connection icon but can not see the phone or sd card on my phone. USb debugging tried on and off.
No problem charging. I have tried various usb cables also and different computers
That is pretty wierd.
Do you have a different computer to check?
I'm having the same issue, but it isn't constant. I spent hours last night reinstalling drivers, different cables, debugging on-off. I go back to stock and try and it works fine, I install clockwork3 and ext4 with TrulyEpic and it does the same thing. Though sometimes it works. I found that my port is a little loose, cause when I move it to one side it looses connection. I think we may need to contact Sprint and get a replacement phone. I really want a brand new one, cause I didn't pay for a refurb, and really dont want one.

Sounds like something is up with the phone, man. The only commonality is the phone.
Especially if you couldn't access it before the flash to 2.2 either.

I find my USB very finnicky on my phone connecting to my windows 7 computer,I've gotten used to just using File Expert to wirelessly manage my SD card.
Hey all. Just got my Galaxy S4 today and I was loving everything about it until... right now. For some reason, the darn USB won't stay connected to the computer. It doesn't matter if it's simply plugged into the computer as an "installer" or as a media device. It'll constantly disconnect and reconnect itself, even when I'm not transferring any files.
It's not the my computer/USB ports, either, since I can transfer files between my HTC Thunderbolt and Nexus 7 fine. I've also tested 2 other USB cables and they all behave the same way.
Anyone know what's going on? Did I get a lemon?
No im in the same boat. Was trying ti connect in today. I reinstalled and un installed the drivers about 4 times. Tried un selecting usb debugging in developers menu. Installed kies and used the drivers from it still no good. Used 3 different usb leads. Phone will still charge from pc and even when im installing the drivers again and connect the phone it will say that your new device is ready to use but still cant access phone, it simply does not show up.
Wouldn mind was working 2 days ago fine. Same usb port and all. And the port is fine cause my old s3 still reads from the same port.

every thing ok with s3 but the problem only with s4
please we need help to solve this problem!
Same problem
I have also been dealing with this for a while now. I have Windows 7 64bit and I have reinstalled the drivers many times through Kies and manually. It seems like the problem is getting worse since initially I could do some file transfer through usb if i fiddled with the device (changing usb ports, unplugging it, etc). Now I am hard pressed to get it to show up on the computer through MTP at all.
This is quite annoying since I am developing an android app and I need a usb connection in order to test it. A fix would be awesome.
I just tested on my sister's laptop and it doesn't have this problem. I clicked around the phone, transferred a 10gb movie, and left it plugged in to see if there were any signs of disconnects. None whatsoever. Odd. Maybe Galaxy S4 just doesn't like something with our computers. This is quite annoying.
I have a fresh Windows 7 64-bit partition I installed the other day so I'll test it out on that and report the results later today.

Oops, missed your post. Unfortunately, it disconnects regardless of the phone's state.
My friend's S4 was doing the same thing on his desktop. Every time he would try to transfer pics the phone would disconnect after a few files.
I tried different things from reinstalling drivers to trying to only copy over a couple of files at a time, nothing worked.
Finally I plugged his phone into one of the back usb ports and transferred over 2gb with no problem and no disconnects since.
My guess is the S4 is a power hog and some usb ports just don't supply enough juice. Try plugging it in to a usb port that comes off a motherboard. Don't use the front ports or usb hubs. Hope this helps someone.

I've been trying all kinds of different combinations of USB leads, phone settings and ports all morning and was just about getting ready to start a new Olympic sport of S4 hurling when I came across this post and plugged my USB straight into the back of my machine and it finally works!! Thank you dirrtpoor for your input - a simple fix, but nevertheless it worked.:good:
I suppose it makes sense that a quad core 1.9Ghz phone would be a power hog.
It wouldn't work on my home PC whatever I tried. Front or back USB ports.
On my dads PC sometimes it would display OK and other times "usb device has malfunctioned" (didn't try the rear USB port)
On my work PC it works fine on the rear ports.
I was having the same problem a few days ago, but then I reformatted the SD card, now everything seems OK.
Even the stock gallery app works now...?!
Guys I was having the same problem. For the life of me I couldn't figure out why suddenly my S4 wasn't being recognized by my computer. I finally went into developer options and noticed a "USB Debugging - Debugging mode launches when USB is connected" was turned on. I de-selected that, connected my phone and now my computer recognizes it again. I hope that helps guys, it helped me.

This may be laughably obvious but I'm a former Apple user, which has it's own dedicated USB connector, so I forget sometimes with the Samsung S4, which has a standard (looking) micro USB connector that I need a USB cable that is enabled for syncing as well as charging...not all USB cords with micro connectors on the phone end will carry the data because I imagine Samsung has made their phone's connector require a different wiring in the cable.
I was pulling my hair out yesterday trying to figure out why the computer wouldn't see the phone..then looked at the USB cable and realized I'd plugged a non-syncing cable in. I tried the cable that came with the phone and bingo, worked like it was supposed to.
Hope this helps, sometimes it's the little things we overlook that drive us nuts.

Hello XDA
So my dad bought a Note 3 SM-N900 and we haven't been able to connect it to the PC at all. The phone is completely stock with all possible updates applied.
Things we've tried.
4 different PCs ,at least 15 different USB ports, 5 different USB cables
When the USB cable is plugged in the phone charges and that's it. No notification in statusbar saying USB connected. Have installed KIES, reinstalled it, installed USB drivers from Samsung's site and from a zip.
NOTHING we've done could show us the USB mount menu thing. I have 3 other phones and have tested many different combinations of phones, USB ports and USB cables. Every single one of them worked except for the note 3. I've also tried enabling USB debugging and nothing still
Have bought a USB 3 cable (genuine Samsung) and tried that, still NOTHING
Very annoyed at this. I have quite a bit of experience with other phones, especially Samsung ones and this is the first time I've ever seen something like this happen.

So the phone detects the PC when in ODIN mode so I guess it's safe to say that the hardware is NOT at fault (Y)
