Most usb cables work to charge my phone, but won't form a data connection with my xt910. I do have one that will. I thought it might be the cables, but they form a connection with other devices.
What is going on????
Also, I just got the usb port replaced thinking this was the issue...
edit: Thought I'd mention, it says a usb is connected regardless of which cable I use in ap fastboot.

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.
Last month I bought an LG Optimus Hub and I have several problems. The first is that the USB port doesn't seem to work. When I plug in the USB cable (any cable) it starts charging but when I remove it, the phone thinks the cable is still plugged and charging all the time. It's the same with the data cable and any charge cable (sans data pins). The phone also would not recognize the data cable plugged, nor does the PC. I know the port does not work but this might still a sw problem. Is there a way to root the phone via WiFi or Bluetooth? If I can do that, I won't mind if the USB port does not work. Else I'll take it to tech repair -and I'm scared of those guys as hell! They don't know anything and keep sending back the same phone with the same problem saying it's either "repaired" or "mobo changed".
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.
Having a strange problem with my phone atm.
The other day I tried connecting to my PC (Win 7) to try and root my phone, only to find that my computer wouldn't recognize the phone. I've had this problem once before with my old Droid X, and that was due to me accidentally reversing the power lines on a homemade USB Host cable, which ultimately fried the USB port.
I thought maybe something similar had happened, as i've been using another homemade Host cable for charging the phone lately. This cable had never given me problems in the past, but I thought maybe something came lose and shorted. However, using that same cable, I can connect a mouse or a keyboard to my phone no problem, so I know that the USB port is still working. Because of this, i'm under the impression that the phone is maybe stuck in host mode?
I thought it might be the cable I was using, but I just bought a fresh one and it's doing the same thing: I'll hear the Win 7 device connected tone go off twice, but it won't show up with the rest of my drives, and the USB connection icon won't show up in the status bar on the phone, although the phone charges fine.
Tried factory reset, didn't help.
Also tried it on two different computers, and no dice. All the computers have the Motorola Device Manager installed.
Any ideas?
EDIT: ****! Wrong section
EDIT: Dunno if this is "progress", but after cleaning the port out with rubbing alcohol, and reinstalling the motorolla device manager, I now get a "USB device not recognized" error every time I plug the thing in... Mouse still works fine though.
Fixed it, for anybody who actually is reading this.
First, since my phone worked fine as a USB host, I tried taking one of my cables and grounding pin 4 to turn it into a Host cable.
No dice. I noticed a resistor on pin 4 though, which I thought was kinda weird for something that's supposed to be floating.
Then I read up about the whole "motorola factory cable" thing. Took the same cable, undid the Host mod, and then pulled out the resistor. Voila! Problem solved.
I guess the "Universal" in "Universal Serial Bus" was just a joke, right?
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 ^.^
Sent from my SPH-L710 using XDA Premium 4 mobile app
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.
