Captivate Cant Connect with USB

I've looked everywhere and cant seem to find an answer, so i figured i'd start a new thread.
My captivate used to connect to my computer just fine, but there was another computer it would just NOT connect too! Well, after a few months, it stopped connecting to my home computer as well.
I have USB debugging on, the phone is rooted and everything. When I plug it in and mount the USB drives, i get drives J and K on my computer, one for the internal storage, and one for the SD card i have in the phone.
When double clicking any of those drives, it just sits there and reads forever without ever doing anything. I can use the SDK to run "adb devices" and it see's the phone, Odin One Click finds the phone but freezes on reading file line, or just fails all together.
Any ideas?

Try reinstalling the samsung usb drivers and restart your computer, that'd be my first step.

You have to be on the touch wiz home screen if you're trying to connect to Kies, otherwise turn on USB debugging and you should be good to go

SeenNotScene: I've uninstalled, rebooted, re-installed several times. I've been having this problem for a couple months now and i've tried everything i can think of. It doesnt work
bkhams: I dont even know what Kies is? I always have USB debugging turned on, and once connected i bring down the drop down menu and mount the USB so i can access my phones files as if they were another drive.

I had the same problem, and Samsung peeps told me I had to use the USB cable that came with the phone, low and behold they were right. Connected right away with the USB that came with the phone, could that be your problem?

I had the same problem in the past and it was actually a hardware problem with the Captivate and not anything with the computer. I ended up taking the phone in and they exchanged it for me.
I do not know if yours could be having the same problem, but that was my experience. Frustrating, to say the least.

Hmm... Could be the hardware i guess.. I know its not the cable though because i've only ever used the cable that came with it.

Have you tried connecting to the USB port directly off the motherboard? My connections were "sketchy" at best when using the ports of the top of the computer case. Once I connected directly off the MOBO, zero problems since.

Sloved!

Thank you for suggestions! My front USB connector is probably connected to some internal HUB, not going straight to the motherboard and wont work. Connecting directly to MB USB solve the problem. I am a little bit surprised... but whatever - M$ bull*hits. I spend couple of hours yesterday to find out whats going on. Thank you again!

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...

Can't connect to pc-USB not recognized, unknown device

I have been searching for about a week now and still can't figure this problem out. I bought this phone used about a month ago and I haven't tried to connect it to my pc until just recently. I am wanting to root and unlock my phone but I can't connect to pc using usb cord although it will charge it.
I am on GB 2.3.6 vuvkj6, stock.
I have tried 4 different usb cords, 4 different pc/laptops and all usb ports. I have also installed and uninstalled several usb drivers with no luck.
My phone can only get into download mode using a jig. Even in download mode, I can't connect to pc. I have tried using Heimdall, Odin, and kies but it just does not connect.
If I can use a jig to get it into dl mode, does that mean the phones usb port is fine?
I just want to be able to connect with pc. Is it possible to flash using my sdcard? I am thinking maybe the phone is missing something to pick up the usb signal or something.
I am lost, any help would be appreciated.

Maybe, I think it's a phone issue.
Do you still have a warranty?

I bought this phone used, so no warranty. If the jig works, does that mean the usb port is ok?

Does the phone charge when plugged in? Have you tried to go ahead and flash even though it says not recognized?

ligitalipeople
Yes the phone does charge when plugged in. I can't flash using Heimdall or Odin. Any other way of flashing?
I have also put the phone into debug mode with no luck.

Have you done a factory reset?

Yes, I have done a factory reset.

FINALLY! I got it to work.

Can you post back here and tell us what you did to get it working in case someone else has the issue?
Thanks and glad you got it going!

I am not sure what made it work for me. But what I did was "clear memory" on ram. I don't remember how I got onto that screen but I clicked on ram and clear memory.
I then pushed the usb into the pc a few times really fast until pc showed somethnig other than "usb device not recognized". Pc then started to show device connected.

if you are using windows i have found that sometimes the usb ports u used for the phone get stuck to the driver that was there in the first place. So what I do to fix this is go into device manager from the control panel and then uninstall the drivers for the specific port that I am trying to use. While keeping my phone unplugged from the computer I then reinstall the samsung drivers, restart my computer and then try to plug my phone in. 90% of the time that has been what works for me.

Ok, I figured out the problem. It has nothing to do with the drivers or clearing ram memory. My problem is the actual micro usb connection. If is a little loose from side to side and when I push it to one side, it connects no problem.

That is the exact same thing that happened to my wife's phone... luckily it was still under warranty...

My phone is out of warranty. At least now I know the problem. It was extremely frustrating trying to figure it out.

[Q] Infuse USB problem

It seems as though the USB portion of my phone connection no longer works. I can charge the phone and nothing else. No communication at all between PC and phone. So, I have the following questions, and appreciate all suggestions.
1. Is it easy to replace the USB port on the phone?
2. Is download mode attainable w/o use of the port?
I've had the phone for 18 months, and is not worth the $200 insurance deductible. May upgrade in a couple months, but wanted to know if this is an easy fix. Using Dropbox currently for file/ data transfer, so it's not a huge deal.
Thanks for all suggestions!

Infuse 4g USB problem
I too have an Infuse with a USB connection problem. The only thing it does is charge. The device is otherwise not recognized on a Windows XP or a Ubuntu 12.04 machine.
Thanks for any assistance.

Try app-Software data cable, and never need to worry about a cable again.

Data transfer is not a problem, when I have Dropbox. I was curious, and I'm sure there isn't, was if there was a way to get into Download mode w/o having a PC connection or being able to use a jig.

Malfunctioning USB port. Trying to root but can not connect to cpu to flash

To start off my USB port seems to be malfunctioning. I can charge but will always get the " charging slow" error. It will even charge via usb port on a pc but it will not recognize it as an external Storage unit. Ive changed the usb settings via developer settings. However i do not get a usb notification on my phone giving me the option to switch the function.
Is there a way to connect to a PC to use flashing tools/ADB in order to unlock my loader as well as flash and send commands to my phone. I can use LG AirDrive but i do not believe commands can be sent through that. Would greatly appreciate help since im lead to believe rooting has just hit for the Stylo 4.
If it is any importance. I am on the stylo 4 bought through best buy not attached to any carrier Q710ULM is my model number

Did you try another USB cable? Ive had several that broken inside and the same happened. Changing USB cable solved it

Ive tried several. It is definetly my USB port. I think dollar store chargers did it in. And now since its always slowly charging i think it won't do any data transfer maybe in fear of loss of data due to bad connection?

Yours is a micro USB port right? Most likely it's a faulty USB port. See if you can get a store to replace it

Yes. Well a Type C but android charger none the less. I guess id have to send to LG to honor the warranty. I didnt purchase ot from a carrier and also did not get aj insurance plan when i connected it to t mobile.
In other words you are saying im SOL for getting on ADB? Atleast until a one click root has a method for this device.

Just to test. Did you test in another computer to see if it is detects it?
My computer corrupted the adb connection due to faulty drivers. Reinstalling windows fixed it because in another computer that i have it was detected normally. It's just to test the whole scenario here. If it doesn't work RMA it to LG

Yes I tested it on a computer as well as multiple outlets. I finally just took the back off and took out the port. It had a lot of corrosion around it. Almost all teal colored. I blame those dollar store chargers. I have no other explanation behind why it happened. Either way there is luckily someone wihtin range selling a bunch of parts on offerup so I was able to pick uo a new port for 7 dollars off of him. When I removed the back I was pretty surprised to see how the "non-removable" batteries are packages in there. Just a bunch of layers wrapped up in thin plastic with some tape around it. haha
