Okay, I'm boggled at this problem. I'll provide all the details and maybe someone much more saavy than I can clear this up or provide a solution:
- Purchased new samsung captivate unlocked from amazon
- Phone is running stock 2.2 Froyo (I factory reset it once, from privacy options)
- Phone has no SIM card in yet.
Problem:
Phone does not connect to any computer or USB port by the provided USB cable
Troubleshooting:
- I have tried to connect the new phone using the provided cable and it only recharges. There is no sound or indication on the PC of detecting the phone. Only a beep on the phone indicating it is charging.
- I have tried every USB port (front and back) of 4 different PCs. 2 laptops, 2 desktops. Including trying USB ports with no other USB peripherals attached. (PCs were windows 7 64 bit PCs)
- The only success I have had - was when I tried it on a powered USB hub connected to a laptop, the computer detected a Samsung android device. It worked for 2-3 reconnect/ejects. Then was never able to repeat this success on any combination of USB hub + PC (laptop or desktop)
- I have tried a samsung stratosphere on the provided captivate USB cable, the Stratosphere usb cable and my Nook USB cable. It worked on all 3.
- The Captivate failed on all 3 (only charged, no USB to PC connection).
- I have tried debug mode on, debug mode off, mass storage mode, kies mode (with kies installed/uninstalled). Drivers installed, then uninstalled. Still only charges, the PC does not detect any device connected.
Conclusions:
- The USB port on the phone is faulty (then I would return it to amazon), this phone is 1 week old.
What I find odd is how it worked for 2-3 connections on a powered USB hub on one laptop.
- The 3 USB data cables I tried were all not "good enough" for the captivate but work fine for the stratosphere and for my nook. (Then I'd find a good enough cable)
- The phone currently does not have a SIM card. (not sure if that is somehow related).
I will probably return the phone at this rate, but would like to know if this is a common problem with Captivate with no common solution.
Side Question:
My ultimate goal through all this, is to root the phone so I can tether to it wirelessly. I obviously can't tether through USB since I am unable to make a data connection through the USB port.
If there is someway I can tether wirelessly without rooting the phone then I may be able to live without using a USB data cable.
Thanks for reading and any replies!
For ur connections issues, have u checked out this thread --- Captivate Connection Issues and Download Mode Help ??
But u may have a port problem... U can get USB Port repair done by a good trust worthy guy here... Samsung Captivate USB Port Repair
And as far as the wireless tethering, u can do it without being rooted, but it will cost u of course. That is, u will have to pay for the tethering plan.
Thanks for the reply. I was thinking along a similar route that the data pins on the USB port were no good.
Seeing that the phone is only 1 week old I will probably return it and either get a new one or different model.
You wouldn't happen to know if this is a common issue with the Captivate? so I should avoid it in the future?
^ Speakin from my experience and what I've read over the past year and a half or so, it is not a common problem.
The Captivate was a great phone in it's day. But these days u have a wide choice of other more up to date phones.
The SGS II is my main daily phone now and my Captivate is my work cell.
Don't get me wrong though, the Captivate is still a great phone.

Just a quick question- I have a Captivate that will charge when plugged in via USB but there is no data connection. The phone doesnt recognize that its plugged in to a computer, and therefore despite being able to boot into download and recovery mode, I cannot use ODIN to do anything. Clockwork wont work either due being on 2.2.
Ive read some other threads where most concluded it is more or less a hardware failure. Im coming to that conclusion myself, but wanted to check with you guys first. The audio jack did the same thing for a couple days-- it wouldn't work when plugged in. It did come back on its own, though Im not sure why.
Im running Cognition 2.2beta3, and cannot flash back to a stock rom nor to any other rom due to the lack of being able to use ODIN.
Is there any other way to flash back without ODIN? Also, if this is indeed a hardware failure- how can I go about getting it fixed? I traded for it on craigslist for an iPhone 4 so I didnt get it direct from AT&T. It did work for the first couple months.
Thanks in advance for your help!
Do you have USB debugging enabled (Settings-Applications-Development)?
If so, you won't get the connection choice screen when you plug in your USB. You can either disconnect USB debugging to get the choice screen, or leave USB debugging enabled and click on the "Select to copy files" choice in notifications.
I have tried with USB debugging on and off, and in various USB modes. None work, as the Captivate doesnt even acknowledge theres a data connection that has been made.
It worked in the past in all modes... debugging with the option to mount the drive, mass storage, Kies, and the media mode. No dice at the moment. Tried a hard reset today... nothing.
Looks like it could be a hardware issue-- just weird as the audio jack had the same issue and seemed to (randomly) resolve itself. Thanks for the suggestion! Any other ideas?

I had the exact same issue as you few days ago. One forum member recommended to me to uninstall the Samsung USB driver and reinstalling it again. It worked as soon as I did this. You should give it a try.
I had a similar issue when performing a master clear and flashing JI6. I am on windows 7, and I noticed that a different driver is needed to use Odin in download mode. I had been sideloading apps as well as transferring files with the stock driver from samsung, but my computer still wouldnt recognize the phone when in download mode. The solution was quite simple, when entering download mode my computer gave me the "driver not found" messege. I just let Windows Update find the right one for me (not sure if its generic or not) and everything worked fine after that. Hope this was relevant to your issue.
And I guess you can't do the phone off, open Odin, plug in USB with vol up/down pressed, right?
Not sure if this will help, but I bought a second USB cable to carry in my laptop case. If I use it I can charge the phone but cannot connect it to a PC. If I use the one that came with the phone it works fine.
I have actually tried some other cables and they have issues too. They all have a larger cable housing towards the end that plugs into the phone, where the one that comes with the phone is slimmer.
A friend at work as a Fascinate and he has the same issue, we suspect that the increased size is keeping the usb from connecting all the way in the phone.
Ive tried different computers and different cables, as well as different drivers. Ive used 64bit systems and 32bit systems... XP and Vista.
The phone itself goes into download mode, though I have to go through the terminal and use 'reboot download'. I cant use command line on the computer as it doesnt find the device... the phone never is identified to it. It just charges.
Is there any way to perform the commands that ODIN does without actually using ODIN? If nothing else, Id like to flash back to JF6 and be able to use the OTA updates. At this point, Im stuck till clockwordmod works with 2.2.
I experienced the same thing. My Captivate would charge, but it couldn't connect to any of three computers (WinXP w/drivers, Mac OS X, and Linux) with either of two micro usb cables I had. I would always get a USB error in some form.
I was on cog 2.1, and was able to roll back to the JH7 OTA update without ODIN. Afterward I brought it to an ATT Tech Center and convinced them it was a hardware failure.
I got a warranty replacement, and it didn't work either.
It turned out to be bad micro usb cables. One was the original Samsung cable, but it was loose, there was plenty of play and wiggle in the sockets of both phones.
The best micro usb cable I've found is from a Kindle. It has a a larger plastic base than the stock from Samsung, but critically it has a longer connector. There's a solid click when connected and absolutely no play or wiggle possible. It works every time.
I don't know if you can restore from 2.2 to JH7 without ODIN. Now that we have 2e Recovery on Froyo (in Cog 2.2 BETA6), could you use Clockwork Mod (Rom Manager) to flash designgear's JH7 OTA ROM?
Try some alternate micro USB cables, you might be surprised!
Im having the same issue, was there any resolution to this from the OP??
I suspect hardware also, and Ive got another Micro USB on order from Amazon and will prob buy one from a store tomorrow also.
the stock cable is horrible, I bought a nice charger the other day and it has a nice click and stay, and since I plugged it in to the new charger it no longer shows up on any computer with the stock cable. Im wondering if the new charger with a tad larger connector spread the connectors just a tad too far for the stock cord.
I tried everything as well, I hard rebooted, put into recovery mode and even deleted all my user data to try and see if there was some software that was blinding the computer to the connection... no luck
Ill let you know what I find.
Same issue here. Has anyone had any luck with a new usb cable? Luckily, I can transfer files from my computer via bluetooth for now, but it takes forever!
I have an issue with my PC not recognizing my Captivate. When I plug in the USB cable to my PC, I can choose to activate USB mode and it prompts me to mount the drive, I say yes but nothing shows up in My Computer. I was able to do all this fine just a few days ago.
I have uninstalled/reinstalled the drivers. I installed Samsung Kies and it doesn't recognize the phone. I tried my phone on another PC and it won't show up there either. I've factory wiped the phone twice now.
Is it a problem with the phone or is there something I can do to get this to work?
I'm having the same issue. Did you get this resolved & if so, how? Tried both ports on my MB Pro & work PC...tried Samsung cable & another USB cable. Debugging is on.
Try Settings -> Applications -> USB Settings -> (select) Mass Storage
I found that when my captivate was set to Kies my computer wouldn't pick it up.
Mine was set to ask on connection. Tried mass storage mode (debugging off) & no dice. Back to ask on connection with debugging on, and still nothing. I've tried all 3 USB ports on my work laptop and both on the MB Pro. Any other ideas?
Did u try enabling "debug mode" and seeing if the PC recognizes it.
The main issue is usually your USB cable. I had the same issue. You need to find an OEM mini usb cable for it to work properly. The one that came with my phone works fine, but when i went to ATT and bought one for my work, it only lets you charge the phone and does not put your phone into USB connection mode.

The ones from MonoPrice work for me and they were like $1.50
Diablo: Been in debugging mode most of the time trying to get it to work. Main issue is getting my personal MB Pro to recognize, so I won't be able to check/tinker much until after work tonight.
cajuntigerbait: I've been using the provided Samsung cable – tried a work Blackberry cable (works fine with my work BB) to no avail as well.
Will update tonight. Any tried & true methods for cleaning the phone port while I'm at it? Thanks for the quick responses, everyone

Try uninstalling all the drivers and try one again using x64 (I know you probably did it already, but just confirming).
Maybe try doing a factory reset?
So i uninstalled the drivers using the uninstaller application that came with the download then i deleted the files off the computer.
went to the captivate wiki on xda, downloaded the 64 bit drivers from that link (look exactly the same as the other links), then ran the installer application from that download.
what happened was at the end of the install wizard it said that: "mss install wizard was not completed... install wizard was not succesfully installed samsung usb driver for mobile phones.".
I did however notice that at one point in the wizad it called the driver x86 instea of x64.
i would be lieing if i didnt say i hated samsung right now. o yea and i think at&t too. ha ha
Thanks for the help! : )
so in addition to hours spent on other days, im about 5 hours into trying to make the phone connect today.
it seems worse now, it only sometimes sees a device it cant recognize.
i tried more batches of driver uninstall/installs and i even downloaded the full kies.
nothing seems to make it go. im about to lob this thing across the room. any other suggestions or people with a similar problem?
any help would be much appreciated.
1) Scrub your system again of all Samsung drivers.
2) Go to Samsung Software & Firmware Downloads and get the Mini Kies program.
3) Install Mini Kies, this will install drivers.
4) Set USB settings on phone to ask on connection, Settings>Applications>USB Settings>Ask on Connection
5) Connect phone to computer
6) Select Mass Storage when the phone asks
7) Mount phone to computer, depends on which ROM you are running
8) Report back,
I'm running Windows 7 x64 Home Premium and have no troubles connecting. Hope this helps.
ok thanks for the tips.
Here's what i did:
Download mini kies from the link (i noticed that there were driver there to but i did not download that link)
Set phone to ask on connection
plug phone into computer
set to mass storage.
mount sd card
computer says "usb device not recognzed"
Mini Kies still says "please connect mobile phone"
i scream!
what do you suggest i do from here?

Have you tried a rear USB port instead of a front? I don't know why but many have claimed this was the trick. It should not work, but for some reason it does for some.

The usb ports on the back of the computer are usually connected directly to the motherboard. The usb ports located other places on the computer are usually connected to the mother board via a secondary card of some type - this adds another level of hardware and software drivers required to make those ports work. Also it is not unusual for some usb to operate at different power levels - often referred to as powered and non powered ports.
So not all ports are the same which is why some people have different results on different ports on their computer.
One other option that sometimes works: turn on usb debugging in settings/applications/development. Then connect the usb. Pull down the notification window and select the button that says something like "select to copy files...". This brings up a dialogue box asking to mount the phone, and you select that.

alright i tried
every single usb port (it a laptop btw sorry should of said that earlier)
and also with and without debugging
computer still says usb device not recognized.
is there any more info that anyone needs? Tried hooking the phone up to a mac also (snow leopard osx laptop) no luck still.

I have built many machines and never had a device work on one USB port and not on another.
All my USB devices that require power, require an actual AC adapter -As for unpowered ports - never heard of that. Powered and unpowered hubs yes - but not unpowered ports.

First, just to make this clear all usb ports are powered, and so long as they are in compliance with the usb standard they are powered to 5v.
Second, what you referring to with powered/non powered usb hubs is a usb hub that has a secondary power source (ie includes ac power cable maybe) vs a usb hub that is only powered by the usb serial bus via the usb connecter to the computer.
What was referring to in powered/non powered usb port is a technology included in some ports that allows that port to use the power of two usb ports in one port - not sure but I believe it is an ibm technology - which is some times referred to slangly and inaccurately as powered usb
Now the point of my post was to point out even though there is a universal standard for usb - depending on how these ports are actually connected to the serial bus on the mother board will affect they way they perform - ie usb on the back of the computer that is mounted directly to the mother board serial bus vs one connected via a pci card.
And even though you have never experienced differing performance in your usb ports does not mean that it doesn't happen - it is actually quite common particularly with devices that both connect via usb as well as charge its battery via usb.
I currently have a computer with 7 usb ports all of which will connect and work with my wife's ipod - but I have found two of these ports that will not charge her ipod. most likely this failure to charge her ipod is due to the hardware (or the software driver for the said hardware) in between these two ports and the mother board.
In all of the computers you have built have you built any that had usb ports mounted directly on the mother board serial bus that you also connected a usb pci card to allow for more usb ports? I guarantee you if you do this often enough you wil eventually build a computer that has usb ports with differing performance.
while the info on usb is nice : ) i would very much appreciate any help on gettingmy phone connected. thanks!

I'm guessing by now you have tried all your ports, lol. have you tested your phone on other computers and/or with other usb cables?
One thing to try is check and see if there are any driver updates for the usb hardware in your computer. You can usually find these updates with the computer vendor and/or mother board manufacturer support.
Sorry I missed your post earlier about connecting to a mac - when you connected to the mac was your phone in debugging mode?
I don't know if it is necessary to connect to a mac, but to get some linux distros to mount the drives in cappi it has to be in debugging mode and while linux and NEXTstep are different they are in the same family, have the same ancestor. maybe if someone with a mac read s this they can let us know if it is needed.
If you keep connecting to different computer with no luck, try a different usb cable.
Actually its connecting to a pc. I just tried to connect to a mac wouldn't work there either.
But I've tried all the different combos of debugging and mass storage options it just says it doesn't recognize the usb device.
I have tried a bunch of different drivers and using both kies and mini kies.
Windows 7 64 bit
Laptop
Captivate (stock everything)

getting unrecognized usb device is almost certainly a driver issue - what ever kept it from working with the mac is something else.
have you downloaded and installed the drivers dg has linked in his odin 3 one click thread?
Second have you had a chance to check if your computer had any usb driver updates? One of my machines would not properly identify my phone that I tried reinstalling drivers on and I found there was and update for the mother board usb controller - after updating it instantly recognized it.
I am having the same issue with an added twist, which is that some USB ports will rapidly disconnection/reconnect the device to windows even though I havent unplugged it.
I have/had adb working on both my old laptop, and desktop. And like the OP I have spent many hours trying to get this to work. Very frustrating.
When I try to connect to the computer I get nothing, just a beep on the phone, I was getting an error and now I don't even get that on my computer. (USB still charges the phone though)
I tried 2 different cables, 2 different computers and 4 different operating systems, Windows based. And lots of Captivate USB drivers.
I have tried Kies, odin one click, mass storage, debugging on, off, everything I can think off.
I tried 2 different Roms, (Apex 7 and 10.1) 3 different kernels and 6 or more factory resets. MTP is listed under apps but when I plug in the USB cable I don't see it under running tasks.
I have a Captivate I896 running Gingerbread I9000 software. I would like to go back to stock but without USB I can not run the software, (computer does not see Captive in download mode or in recovery mode.)
Would anyone know how to troubleshoot this, is there a way to debug the software and see just what is happening on the phone.
Dam you have tried a lot of things... lol
I have a suggestion... have you try 'adb'?
Let me see If understand right...the problem is that ODIN is not recognizing your device and you want to go back to stuck? you don't specify if you can transfer files between your computer and phone...and also if you can connect with 'adb'.
Probably was you micro usb on your phone got damage...have you been experimenting with a jig?
ya I have tried adb and when I type in adb shell I get a response of no device found. and no the only thing that went in to the usb connector ever, was the Samsung usb micro cable. I think I will take it to Samsung next week if I can find the service center around me, I think it is still under warranty.
Check to make sure the cables you're trying are data/charging cables. My stock cable went out so I found one I had in the closet. The one I found would charge but no data passed (ie. PC wouldn't see it).
I bought a new N7000 and everything works fine except I can't get it to connect via usb. Kies won't connect to the phone but everything else works fine with it. I can transfer via wifi with Kies.
The charger that came with it also wouldn't work, so I got my G2X usb cord and wall adapter and it charges that way, otherwise, the computer won't recognize it.
After rooting it Windows 7 finally installed the drivers for it, and the computer showed it was charging (still no usb storage though) and once I unplugged it and plugged it back in again no response.
Tried mounting usb storage through CWM and still nothing. I would think if there was something wrong with the charging port that it wouldn't work at all, but I can charge via a/c adapter. Confused.
A good test for this may be to try the Android SDK to try and get an adb connection. The reason I say this is it bypasses the samsung usb drivers and uses a generic set. If you can get an adb connection and pass a few basic commands then you'll know it's not hardware issue.
There are a few possibilities for this error...
1. MTP service is not starting correctly on the device which would suggest needing a rom reflash or factory reset. Using the Android sdk connection will help determine this
2. MTP not starting correctly at pc, suggesting driver installation/corrupt download of samsung drivers, again android sdk will help determine this
3. Usb port of pc issue. On my rig, connection usually fails off front ports, but rear ones work fine.
4. Cabling, does sound like the cable/charger that was supplied may be faulty.
5. And finally, the hardware usb on device is faulty.
How were you able to root.?

Once in download mode Oding would recognize the device. Other than that, the computer never will.
