usb connection with pc suddenly dead

Hello suddenly my nexus s stopped connecting with data with the pc it only charges, tried with 3 diffrent computers with diffrent os , no menu popping on nexus and nothing connected on the computer(like i didnt connect anything), i removed the battery left it for some time installed stock rom still nothing.It was acting normally for a second and the other it stopped any help appreciated!

Are you sure you're using the cable that came with the phone? I have an LG Wink featurephone here that uses the same connector at the phone end -- its cable will charge my Nexus S (using the computer, obviously, but also when used with either the LG or Samsung charger) but no USB connection happens when I use it. Only the cable that came with my Nexus S provides a USB connection when I connect to the computer. I guess there are pinout differences between the two cables.
If you're sure you're using the right cable, I would guess that it's gone bad if it doesn't work on any computer. You can buy an (overpriced) replacement from Samsung or maybe a cheaper one on eBay or at a retail store. If the latter, be sure the seller lists it as compatible with the Nexus S.

it happened with the original cable ppfff i dont know...

same problem

Hi
I have the same problem
I have no idea what the problem could be.
We are not alone with this problem: code.google.com/p/android/issues/detail?id=13553
Now installed stock rom as well but still the same problem.
If i starting the NS in the bootloader mode the phone is not recognized by the computer.
It would be great, if someone knows a solution!

I've been trying to get help with this for weeks. No one is even responding to my posts. I thought it was something OBSURDLY simple, such that people didn't even want to waste their time responding to me.

Seeing same problem, No connetion via USB
Posted problem in General,, http://forum.xda-developers.com/showthread.php?t=1104245
Tried different cords, different computers and operating systems,, did cold start several times on phone (removed battery) still no luck, I am running totally stock
Curious do any of you have the Google Music Beta?? (maybe a over zealous rights thing?)
just tried it with a Win 7 machine that had never seen it before and it said it could not recognize the device,, me thinks that the MS device driver DB is messed up buy some recent Win update??

My phone charges just fine. And my USB connectivity was fine until I manually installed 2.3.4.

~I had usb connection problems after upgrade to 2.3.4 a bit different but I managed to get the USB back by formatting the SD card.

I was on 2.3.3 when this happened, i tried to flash 2.3.4 then and again it didnt work but the strange thing is that when i was moving the mini usb the first times up and down it was shown for a moment as a broken usb device.Then this stopped and was not shown at all on the computer and finally the phone charged super slow when connected to electricity

Beginning to believe that it is a physical prob with USB connector on phone. It seems to start/stop charging when wiggling usb on phone but no mounting. Doe anyone know best way to resolve , T-mobile but bought from Best Buy? so to Best Buy? FOR SUPPORT /EXCHANGE? suggestions?

I've seen loose connections before. My suggestion ain't the cheapest but the plug, on the cable end, shouldn't wiggle. I went to a corporate sprint store, the ones that actually have working display phones, and got their usb to micro usb data cable. The thing with that cable is when you plug it in the phone side, it goes into the jack firmly. You can almost feel the little locking tabs click into place. There should be no play or wiggle with that cable as long as there's no damage or abuse with the jack on the phone. IMO, that's a good data cable. It's never given me problems before.
Also, sometimes the cable is only wired for charging. A true data cable will be wired correctly and be able to both charge and transfer data. Usually the cables that come with the phone are crap quality. I don't know if my suggestion will help but it won't hurt to have a good cable for data transfer and flashing. The last thing you want is a flaky connection from a cheap cable when you're flashing roms. Russian roulette with bricking a phone in a worse case situation.
Did you try reboot the computer and the phone? How about a different usb port? How about unplug any other usb device in case it's conflicting for some unknown reason? It sounds like so many people with windows 7 are having problems. Usually always happens with a new os that's released. Xp, for flashing devices and programming different hardware devices, has never given of a problem. I have a small partition with xp on it just for that purpose only.

off to Samsung for repair for me...
After time on phone with them and a factory reset belief is that the usb connector is defective. BTW Best Buy just hands off to Samsung 1-800 #
So Back to a barely functional G-1 for a while, glad I could find it!

So is Samsung or the carriers replacing or fixing units?
My USB data died shortly after 2.3.4 ota update.
Wifi FTP is fine for data transfer but I want USB debug to work...
Shame on google and Samsung, this bug has been around for months.

no shame on anyone...
I went through a factory reset with Samsung on phone that isolated the problem to what is apparently a loose usb connector, nothing to do with software... only hassle is sending it in for repair, as` mentioned problem needs to be dealt with Samsung customer service (not carrier or Best Buy), they were fine on phone...

Me too.
I disconnected my tablet, shutdown and powered up. Reconnected dock, and it started working again.
I had to do it a couple times. I thought my dock was bad, until it started working again.
Good luck.

Mine does the same thing since the update. I have a lot of my movies on a external portable HDD and the TF won't recognize the insertion. I have to reboot the TF for it to recognize a thumb drive or a HDD or a SSD drive plugged into it. Extremely annoying.

My TF101 happen the same, need to reboot to get the usb and card reader to work. And after it sleep, it would not, reboot again and work. Anyone have any idea to keep it alive even it go to sleep?

we have to take this problem to asus
someone send the problem to asus?

[Q] Can't use OTG on Tab 7.7

Hi all, I have had a Tab 7.7 for 12 months and have been using an OTG adaptor to copy jpegs from my camera's SD card to the external SD card in my Tab. All of a sudden the whole process has stopped working. My Tab 7.7 has ICS 4.0.4. and is NOT rooted. Previously when I plug in the OTG adaptor the File Manager appears showing the folders on the SD card in the adaptor. When I plug it in now I get the message "USB mas storage removed safely" and that's it. I was thinking I might re-flash the rom but since I can't even get Odin to load on my windows 8 PC (it flashes on the pc monitor then goes off) I really can't be bothered. I went to the trouble of running Odin on a windows 7 PC at least it loaded on 7 but wouldn't acknowledge the Tab being connected. I thought I might have a driver problem, but has anyone on this site tried downloading a driver for samsung tab 7.7, it's a bloody nightmare. You get all sorts of crap from checking what drivers are missing or outdated on your PC then having to by a copy for $29.95. I'm really over it. When I rooted my Mororola xoom 12 months ago and flashed ICS I had no problems at all, there wasn't a link like we have now that sends you to a site that takes 5 hours to download a tar file or you could buy a subscription and do it in 9 mins. Can anyone please offer any assistance with my problem before I toss it in the bin. Many thanks

Yeah maybe try a few different things connected to see what exactley is the problem.do you have any other usb things you could connect?

Thanks, I tried a laser mouse and the led under the mouse dosent light so I suspect the 5volt rail has gone somewhere. I'll pull the back off and check connector. I will post outcome.

Have you tried a different sd card?

Yes sure have, 3 to be exact. I've changed my mind about looking for 5 volts on the usb connector. I'm just not going to bother trying to connect a SD card through the USB port. Life is too short to stuff around

Moto G sometimes shuts down when connecting OTG

Hi,
I have a weird issue with OTG.
Sometimes when I connect a SD card to my Moto G through OTG, the phone's screen just turns off and I can realize that it powered off.
So I have to reboot the phone. This situation doesn't happen always, just sometimes.
First, I suspected it's a CyanogenMod bug, but it's not. I wanted to flash a zip through OTG in recovery and when I was in recovery and I connected my SD card, the same happened.
I can't believe why this happens to me. Is it a hardware issue?
I think the micro-usb connector is ok, because I tried to play with it via charger's connector, OTG cable (without SD card reader) and the issue has never come up this way.
Did someone experience this? Does someone know why this happens?
Thanks in advance!

Mmm I don't use the CM but it's never happened to me... probably a software bug. Which app do you use for OTG management? I use stickmount, very good app, probably the best.

I don't use any third party app for that, and it happens only sometimes.
I tried an app called OTG Helper and my Moto G powered off more times while using this app.
Stickmount does the same, more shutdown.

Could be a bug of your ROM or bad compatibility... You can try to reflash all but probably this won't help...

Agreed sounds like your particular OTG device [sd card] is having issue with phone.

Thanks for the idea. I guess I found the problem.
I have tried 3 devices with my OTG cable and my phone powered off with all the 3 devices.
I found another OTG cable and I have tried the 3 devices again. My Moto G has never shutted down with this cable.
So, my first OTG cable is messed up. It's from eBay.
I'm so happy, the problem isn't in my lovely Moto G! :angel:

Can't use OTG-USB in TWRP on Grouper

Hello, I've flashed a couple of ROMs on a Nexus 7 (2012 - Grouper), using TWRP and a USB memory.
Now, when I tried to flash a new ROM, the USB OTG is no longer recognized.
I've tried two different OTG cables and a couple of double ended USB sticks, but they are not recognized.
I've also tried ADB sideload, but that didn't work either.
I've had a similar problem on other devices, so I just put the ROM on an SD card. But the Grouper doesn't have a slot for an SD card.
The same thing happened last week, but the OTG came back after navigating around in TWRP. Now it seems to have permanently gone.
Any ideas anyone?
Thanks

I'm wondering whether this could be a hardware fault, possibly due to using a faulty USB adapter some time in the pas.
Is it possible that a faulty adapter could produce a hardware fault in the tablet?
In that case, is there any way of getting a new ROM onto the tablet memory and so give the tablet (my wife's) a new lease of life? TWRP is working, but that's all. Maybe jumper leads onto the USB connector. That could work if it's just the connetor, not a softare prob. I don't suppose anyone's tried that.
