So this issue started a few days ago. Any time I plugged my phone in it would constantly connect and disconnect from the pc. I've tried multiple usb cables, ports, and the 3 PCs I have with the same result on each. Now when I plug it in, it is no longer being recognized by the PC, Odin, ADB, etc... It will charge but that is it.
I have a warranty replacement coming to me however I need to be able to get this one back to stock... Any suggestions?
Before anyone asks, NO it has never been wet, dropped, damaged in any way, set on fire, caught in a land slide, earthquake, what have you.. The phone itself functions perfectly fine. All drivers are up to date, none of my PCs configurations have changed. I have one I use specifically for app development and not even that one will see the phone.
I had the same problem. I used a different cable and it all worked better....now with that said it happened again so I flashed my phone back to stock and all was well.
Then went to flashing ROMS.

Really check out the micro usb cable. A bad cable will just about always allow a device to charge, but data transfer is another story. If you really have tried a few micro USB cables, then it the problem relies elsewhere. Try restarting both phone and PC, and if neither works, sounds like you have a busted port on the Skyrocket.
Thank you both for your responses. I am a PC technician so I followed my usual troubleshooting steps to figure this out. I narrowed it down to either all of my cables are bad (not a chance) or the phone is just f**ked (likely). Ah well ill have to try to use another way to force the stock firmware and recovery on here. Lol
HTC = Hate The Consumer
I use my old Nokia OEM USB cable. Connects with the right number of pins on the USB connection end. I'd check your USB cables for # of pins . Skyrocket uses 5 I believe. Also that there is sufficient power to your USB ports. Aka avoid front USB ports which could only be 4 pin....

When you plug the usb cable in, do you see the usb icon at the top left of your screen? I have to pull that window down to tell it to connect to pc, then confirm it again before mine connects. Mine doesn't auto connect on its own.
I see you've been a member for a few years so if its not connecting, that really sucks man. Hope you get it figured out.

Not running the AOKP ROM are you? The R3 build had an issue with this, and all AOKP will disable USB to PC if you enable 'fast charge' under ROM Control...
Good luck :S
According to what I've been reading you can try using the *#7284# code and setting the USB portion from PDA to MODEM and then back to PDA and it would kickstart the connection. No dice for me though. Ive been through 7 different USB cables already.. I am not about to go and buy one just to keep playing with it my other phones connect just fine using the same cables. No, I am running the latest Sky ICS

After I installed Froyo on my Captivate, USB is not working. When I connect it to my Win7/64 and Vista/32, I get the "USB device not recognized" on the computers, regardless if I am in USB debugging or not. I reinstalled the Kies s/w in the hopes that the drivers would then recognize the Captivate, but that doesn't work. So obviously USB tethering and Mass Storage are not working. Has anyone else had this problem and how can it be fixed? Thx in advance!
Have you tried mounting the phone in debugging mode? This has always worked for making the drives accessible.
Sent from my SAMSUNG-SGH-I897 using XDA App
Yep, I stated above that I tried with debugging on and off, and it didn't matter. Usually the phone would mount differently with it on or off, but now it's just not recognized. Very strange...
have you tried using a different usb port? i was having the same problem and got it to work when using a different usb slot
I'm having the same problem. It also often decides not to recognize when I've plugged it in to charge. Used 2 different usb cables, 3 different usb ports on my tower, usb ports on 2 different laptops, and plugged in using the stock usb cable/charger combo. I'd like to flash a new rom, but obviously that's not an option for me right now. It double sucks, cuz I just did a factory reset. I also tried the above suggestions to no avail
EDIT: When I unplug the phone while charging (once I finally get it to recognize that it's hooked up and should be charging), it still shows the battery icon as being charged
same problem. sort of getting mad. i have tried lots of stuff. un install re install drivers a couple times now. both pre select and post select usb modes on the phone well any way lots of stuff. all the usb plugs, tryed putting the plug in the pooter first then the phone on all ports. phone with sim in/out all ports and memory card in/out all ports i reall want to try darky's rom. as sweet as xxxbunker.com is with flash on the phone, i would trade it back for 2.1 so i can use my headphone jack for speaker phone again. please some one help
#edit: my wifes phone still works fine on mounting with the vista pooter. she still has 2.1#
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!
So my girlfriends little brother gave me his skyrocket. He asked me to backup his pics, which I did with no problem. I then did a factory reset. After that, my computer does not recognize the phone! I've tried different cables, different computers. My girlfriend has the exact same phone, connects right away.
I even flashed it with a different rom and put ICS on it. No luck! I then proceeded to take it to a phone repair place, thinking it might be the actual usb port. They said they checked out the port, and it look fine. All solder joints were good, no bent pins.
The weird thing is, is that it connects on an average of 1/20 times! It charges perfectly too. The phone doesn't go in and out of charge mode if i wiggle the cable either. I'm kind of confused! Is there a file on the phone that tells the computer what it is when connected? If so, can I manually replace that file? WHAT DO I DO!
When you goto recovery mode can you goto mounts and say mount usb? and does the pc recognize it then?

Kind of. We had trouble with it when flashing it. I personally didn't flash it. I watched my friend do it

You could try installing the drivers again..
You mean on the computer? I did that. No luck. It does connect more often though WITH the drivers.
I had some problems with USB connectivity too. Using the cable that the Skyrocket came with solved my issues.
Have you tried any combination of restarting and reinstalling the drivers?
Swyped from my Nook Tablet, running CM7.
Yes. I've tried multiple cables including the stock cable. Installing drivers, restarting both devices. I have definitely ruled out the cable, the PC ( PC's actually), and the physical USB port.

I had similar issues, messed with phone for a bit and came up with this
System settings>more>USB utilites
Now I got a screen that says USB mass storage with a button that says Connect storage to PC. Tap Button.
A window will pop up asking to Turn off USB debugging (if on) Tap OK
Connect USB cable to storage (plug USB cord into PC).
You should now be at the USB Mass Storage screen, Tap button at bottom (Turn on USB storage)
I found this to be the way to turn on Mass Storage since I flashed ICS, I believe. Hope this helps you, it took me a little while to figure out.

Of course, that's how it's always been except in a slightly different location on ICS
I've tried that also. Didn't work

it basically sounds like the USB port on the phone is dead. Warranty that sucker
I took it to a repair shop. They said the port was perfectly fine!

Not to mention that it was working perfectly before I did the factory restore
Sent from my SAMSUNG-SGH-I727 using XDA
how exactly did the repair shop test it?
try plugging it into another usb port on the same computer or try using a different computer. It could be the usb port on the PC itself.

That's the first thing he tried, it's in the OP
yeah i've tried everything! The repair shop determined that the port was good by examining it under a scope and they also said they tried re-flowing the solder joints. They said they wanted to stay away from replacing the usb port because it was very difficult to replace, not to mention they didn't warranty the job!
Someone has to know the answer to this!

if its still under warranty replace it, thats all u can do. No one else in this forum besides u can physically touch the phone, so if you've tried all suggestions thats all thats left
i have the same problem but mine is little different, when i power off the phone it keeps on going to download mode, i keep on restarting it and it goes back to download mode, i flash stock rom and it does the same, i flash ics rom and it keeps on doing the same can anyone help?
So I flashed my infuse from Froyo to GB to ICS and then to JB...but ironically the same day that i flashed to JB, my download mode stopped working.
Ever since I flashed to JB (CM10 and slimbean so far) My computer says "USB device is not recognized or has malfunctioned" and I cannot put the phone into download mode via 2 buttons and usb cable. When I plug the phone in it just turns on and starts charging and the computer wants nothing to do with it.
I know the USB port works because it charges without a problem. I have also tried 2 other windows 7 PCs, and my macbook. Can't get it into DL mode or to mass storage.
Any ideas?

Just cause it charges doesn't mean it works...that just means the power part works...power and data transfer are two desperate things...I've had cords in the past that after a while stopped working as data cables and became strictly charge only cables...
So, have you tried a different data cord? Its likely the data transfer cables got damaged due to normal wear and tear (these cords arent made to last...)

Try a different cable, just do it. Denial is not good. I had same problem then got a different , different cable and it worked. As i tried three cables. I do believe one did work to get mass storage but it didn't work to flash my xperia x10, that's what bugged me.don't really remember as i have bricked these phones so may times experimentation ya know, it is hard for me to remember .
as i was flashing my infuse at the same time i used the data cable that does work with the infuse and my other cable wasn't working it wouldn't recognize and ahhh went through my head so after infuse got done i switched cables and vola it worked.
If not then reinstall drivers reboot pc and get a data cable that is really a data cable .

So for a while I haven't been able to connect my GSIII to my laptop cause it pisses me off. It will constantly disconnect at random times, no matter what USB port I use.
I have a Clevo W350STQ laptop, which has two (2) USB 3.0 ports and one (1) USB 2.0 port. My only shot at connecting it is using the 3.0 ports, as the 2.0 one will be worse.
With the 3.0 ports I can have the phone connected for anywhere between 10 seconds and 5 minutes, but it's never been connected for longer than 5 minutes. The 2.0 port connects and disconnects every second.
It's not the cable as I use it for charging and have used it for connecting other phones
It's not the USB ports cause I use them all the time for other things, and I even re-installed my USB drivers.
What could it be?
I did a factory reset and updated to 4.3, and it only happens with my laptop.
Edit------------------------
I needed to transfer files over and tried using Kies Air because I can't use Kies 3, and Kies Air just says that java isn't installed, and I won't upload every song one by one.... And when using Kies Air, I have it sent to the desktop and every time I try to open it, it just says it cannot be opened.
Here's a photo of what comes up when I uninstall the drivers completely, restart computer, install the drivers, then connect my SIII to my laptop.

You're probably not using a very good usb cable. Just because you're able to charge through it doesn't mean you're going to get good data transfer. They use completely different wires, and transferring data is much more reliant on a high quality cable.
I have a charging cable that works fine for charging, but won't connect to my computer at all no matter what. I bought a 3 ft OEM cable on amazon that works great for data transferring and I only use it for that purpose.

I'm using the OEM cable that came with my phone. The cable works perfectly fine on my desktop, it's only my laptop. I have tried different cables as well, and they all produce the same results. This is why I'm stumped... I'm currently using AirDroid to transfer files and stuff to my phone, but I would at least like to get the USB connection working.
I've tried re-installing the drivers and still nothing. I tried using the mobile drivers from the samsung website, no work. Tried using the drivers that install when you plug the phone in, no work. I can't seem to get anything to work :/

I don't think is ur fone since it connects to ur desktop. Have u tried different devices with same cable and/or different cables. . If ur jst putting files into ur external sd card y not use an adapter or put the sd card in another fone or mp3 player to transfer the files then back to ur fone.
Most likely it is a mechanical failure in the phone USB connector , mine will not connect at all . I have seen several complaints about this issue. Looks like the connections are breaking internally in the phone and it cannot be repaired. Software is never intermittent, hardware often is.
