Hi,
Having a problem since a few weeks with my s3.
Normally i could connect wiht my phone to any pc,, without any problems. Either it be unix, win, whatever...
Suddnely it stopped working, only thing that happens is charging when i connect it to my pc. Different cables tested, original one, etc..
Connecting it to different pc's resulted in a no go.. so it must be phone related.
No windows pop up, or anything!!
So I figured: Let's install a new rom.
Tried ultima 15 rom, got a different CM rom now (sentinel)... all to no avail.
Is it possible that this has something to do with my radio?
rom info:
android: 4.3
baseband: CEEMG2
Anyone have an idea what to do? Even ADB push ain't working..
See your identical post
I experienced the same problem when m using the Galaxy Nexus S But it was solved by using the app from play store named SD booster... In this app m just set the value of sd card to 1024 give root access and Boom my phone is connected as normal
If this not help then i seriously recommend you to replace the charging port of the mobile through samsung outlet
Go into developer settings, some ROMs may have different ways to get into develop er setting and after you get in make sure USB debugging is enable ^.^

Usb debugging is not required for phone to pc connection see basic faqs and guides .
But as OP has ruled out drivers and cable that only leaves the phone so its worth trying .
Usual replies are
Drivers
Cable
Dirty USB Ports
Not connected to main-board usb port .
I had same issue with my Galaxy SII and when i took it to service center they said mother board needs to be replaced.
So after that SII was good as new.
Got same problem here.
phone is charging over usb , but no data connection (tried different usb cables, different usb ports, different pc etc) but nothing..
also.. tried in download mode and so (after reading forums..) but without success.
then i decided to dissasemble that phone and look, what's inside that beast
cleaned usb port (inside, with contact cleaner), resoldered all pins and etc..
reassembled it back to one piece again and still, no data connection, but only charging
so, here i am, what to do next ? change the usb port on motherboard ?
(visually, everything looks right, good solder points and etc.)
Thanks, Martin

if anybody interested:
i've got it working again :victory:
basically, the problem was the hard way (crap usb data connections on motherboard)
soldered new ways for data+ and data-, and now it's back alive again...
(pictures of ways in attachment)
Martin
see you fixed it already but a note to others :
try using usb port right on the motherboard instead of the case front panel usb ports.....connecting to the front usb ports didn't work for me on some roms, but the rear one always connected so I just have a long cable running out of the back to connect my phone and it works on all roms I've used so far
Nice work hani93, i unfortunately do not dare to desolder and solder this stuff
I've noticed another thing though which is weird!!
When i tried to charge my phone via the power charger (the ac one?), when i check my battery view it still says that i'm charging via USB.
I don't think this is correct, i thought it should say AC or something and when charging via USB port on pc it should display USB?
I think this might be one of the issues that it's also not popping up on the computer.
Anyone know what is causing this or someone can confirm that when charging via power supply it should say something else then USB?
Just confirming your question when charging by PC it says (USB) and when its charging from the Mains it says (AC).
hmmm... guess it must be a hardware issue then?
Either usb port or mainboard... christ...
open it up and cleaned the contacts a bit of the usb port...
Still not functioning..

try to go into Download mode (volDown+Home+Power) and then connect usb, same situation?(eg, no data connection to pc ?)
if nothing again.. try to clean usb port inside (where you plug usb cable), sometimes there is dust and etc. then it stops working.
also, how did you clean contacts on motherboard ? i suggest to take soldering iron with clean bit, and drag iron along the pins.

when phone is plugged into PC it will not show a usb connection on the phone it just charges the device the computer also does not see the phone. I have also plugged it into my macbook and nothing happens. Anyone else have this problem or any solutions?
What's your ROM?
when you put the usb in the charging port on the TB, does it feel wiggly or loose to you? It's supposed to be a solid connection. My last TB was loose in the charging port and would do the same thing
usb
try another cable, try taking out the card and putting it in the pc, the data pins might not be establishing a connection
Hey guys after trying everything possible and seeing that my buddys TB connects fine i took it to Verizon and their sending a new one in the mail hopefully that solves everything
I have the same problem, computer will charge but not recognize usb connection nor will phone recognize connection? Have had this problem across multiple roms thinking it was software problem but to no avail. Have tried multiple cables and computers? My connector appears to be in good condition visually , which probably doesn't mean much. Just wondered if anyone could think of another possibility before I lean towards hardware problem?
Had this issue before get a new cable if that doesnt work idk thats all i had to do.
I've tried 4 cables and 3 computers and 3 roms.... Guess It's a hardware problem.
had the same issue and it was hardware and my phone was replaced by Verizon.
Sometimes if you don't plug into the usb 2.0 port, things can get fishy. Usually the 2.0 port is alone opposite of the other usb ports on laptops.
Yesterday I plugged my phone into my PC and went to set it to mount as mass storage but the USB connected notification wasn't there. The phone charged fine off the USB, just didn't see the PC.
I thought this may be a PC issue until going to use it on my HD Multimedia dock, phone wouldn't recognize the dock was attached. Then went and tried it in the car dock, same thing, phone charged but didn't go into cardock mode.
Also not sure if this is related but since then battery has been discharging quite quickly.
Please help.
Regards
Bruce.
Hi, did you use the original cable ?
I noticed that the cable from my galaxy S II didn't work with the razr droid !

This will probably solve ur problem:
Uninstall all motorola from PC
Reinstall motocast 1.29
Connect ur razr in every mode, and wait it reinstall the drivers.
Cheers
Thanks, but it's the phone that's not recognizing the usb cable is plugged in. I've tried it on three PCs and the darn thing will only charge, not give usb connection options.
Get a small paintbrush and a can of Dust-Off or other compressed-gas sprayer.
Hold the phone between your knees with the USB port up. Swirl the brush around inside the USB jack while blowing air into it at the same time.
Try it now.
Micro USB jacks have a very nasty habit of collecting pocket lint. It can prevent the cables/plugs on any device from making a solid electrical contact.
This will likely become a routine operation that you perform once a week or so.
You can buy micro-USB rubber plugs that protect a female jack from damage and dirt. You should try the usual places to find one; Amazon, DigiKey, Fry's, JameCo, etc.
If this doesn't get it, you may be looking at either replacing the jack (if you can un/solder very small things), or replacing the phone itself.
PS: If you have geeky friends who like pranks, get a high-powered magnifying glass and check for Scotch Tape on the USB jack contacts. I've done this to an obnoxious iPhone FanBoyz phone before. I confessed before his battery was completely dead...

Did anyone ever find a solution to this? I'm having the exact same issue, have tried clearing out the USB port, different cables and every port on my PC. It charges on connection but doesn't recognise that it is connected to a computer rather than a power port.
Any advice?

Are you on stock or custom rom ?

Stock. I'm thinking of doing a factory reset as it has been freezing a lot recently and I suspect its a software issue, but I was hoping to do a proper backup first, however I lost root a while ago when I updated to ICS . I don't know if the freezing and not recognising computer could be two sides of the same issue?
My problem is that I cannot connect my Galaxy S II to computer. When I try to connect it only says "unknown device". I have tried with newest Kies and without Kies. With multiple computers with Vista and Windows 7 32bit. Also downloaded Samsung Galaxy S drivers manually from web but with no avail. And I have tried with Usb-debugging on and without it. I also tested USB-mass storage setting but it does nothing. Computer also says "unknown device" when I try to connect phone while in download mode.
The charging works btw.
When I connect the cable my phone just makes the normal sound but the mass storage android man newer appears to top tray. I have also made factory reset and cache delete from recovery but with no luck.
I would like to flash different rom with Odin but I cannot do that when the connection is not working. My current rom is official XXLPQ ics. The usb cable isn't the problem because I have tried with different cables which work normally with other phones.
Is the warranty repair only solution? Really wouldn't want to be without my Galaxy during the repair time.
Sounds like it's going to need a check over, if it wasn't for the fact you have tried multiple computers AND leads, as I had a similar problem but found it was down to my PC needing a fresh install.
Unless others with similar experiences have advice it doesn't sound good, as though pins 2, 3, or 4 have problems maybe, or that the board within the phone has bent up or down through rough handling/tug on the cable.
When did it start happening? I had a fright by tripping over the phone while plugged in, and ripped the plug out while launching the phone across the room. It broke the charger and thought I'd killed the port on the phone, but found if I propped the plug up and put weight on the phone it would connect, like this...

Might work if the board has got a whack like mine did.

As I mentioned earlier I have tried all that.
Hello, i am new to xda-developers, so please have patience with me
I was using my original usb cable to charge my phone from my laptop. But one day some strange things started to happen, when my phone's battery was completely depleted i connected the usb and phone started turning on and off very often and I wasn't able to charge it even a bit. When connected to wall socket charger everything seems to be fine, it's charging.
But now the usb is not working, neither computer sees it (before i used it), i used other cables, no good. Now it's original ginderbread ROM, maybe i should reinstall it, but i can't do anything since usb is not working in any way.
Maybe someone of you had similar problems and know how to solve it?
Thanks in advance!

Thanks for the quick reply!
I tried cleaning it with Tooth Brush and even used special liquid for cleaning electronics contacts and corrosion removal, everything seems to be clean. But still nothing happens when connecting to laptop.
P.S. Same cable is working when charging from wall socket charger, so it seems the contacts must be clean and intact (at least power supply contacts), so maybe it should charge from laptop?
P.S.S. I forgot to mention, when the phone's battery is depleted, when i connect to laptop, it doesn't charge but in time phone becomes hot. So maybe this would prove it's a hardware problem?
Try different laptop USB port. If this doesnt help than probably your data cable is faulty. Just replace it with another one.
I think Your phone is fully operational if AC charging without any problems.

I have already tried different laptop ports, even different laptops, already tried with different cables (which all functioning properly with other devices and all are marked U2). I am pretty sure that's not connection / cable problem.
So I got a new Galaxy Note with a busted screen, and I combined the two (my no audio one) to make a working phone. Now the new Frankenstein phone has audio, the screen is perfect, and all is good. Except I can't connect it with USB to my computer. It charges over USB, but when I connect to my computer I get an error that the USB device has malfunctioned. I swapped the USB board with the spare I had, but it doesn't work still. I've tried a few different cables, different PC's, and enabled USB debugging, and it doesn't work in either download (odin mode) or regular mode.
Any ideas?
Maybe it's the USB cable.

I'm gonna post here for later reference also.
Same exact issue.
Was your USB port confirmed working on your no sound device recently before the swap?
I bought a new replacement to swap in. I'll keep you updated if it works for me.
5 different cables, 4 different PC's. Only one authentic Samsung cable out of 5. Maybe that's my issue, but I dunno.
I bought this thing used. I just need rooooooot..... :crying:
So I fixed it. Turns out the connector on the motherboard that the USB daughter board ribbon cable connects to was dirty. I took some rubbing alcohol on a q-tip and cleaned it off. Right after that it worked perfectly.

Replacing my micro usb port fixed my issue. The downside is... I broke my sound in the process.
I wish I could just leave well enough alone sometimes. At least I'm rooted on JB now. :cyclops:
EDIT: Apparently my phone only likes my old USB module and not the new one as far as sound is concerned. "yay"
Every time I need Odin, I have to swap usb also.
maybe this shud work for u , it worked for me
