So I've searched through threads and can't seem to find any solutions. I'm running Axura 2.1CE w/ JK3 kernel. I've used multiple cables, on different computers and none of the computers are able to even detect the device. Any thoughts?

I had this happen to me a couple of times. One time i just needed to restart my phone, and at least once it was a bad flash and I just had to reflash over and master clear. never had it become a permanent problem.

can you not get into download mode using hardware buttons?
The usb cable that came with the phone is not working for you even after installing the proper samsung usb drivers? What windows OS are you trying on?
Make sure it is a data cable and not a charge only cable. Look at the tag that is on the cable and it should tell you what it is.
Like UpNSmoke said.. make sure your using the correct cables.
It is suggested that if your having issues with a computer recognizing your phone to plug the cable in to the USB Port that is on your Motherboard on your Computer.
I would also suggest that if you haven't already - use the drivers that are in Design Gears ODIN 1 Click Back to Stock (links also provided in the sticky here as well). These are the one's I've been using since I've had my phone - and haven't had any issues.
Another thing you can do is - plug in your phone - and then re-install the drivers while the phone is plugged in.
And lastly.. I seem to have better luck with my Windows 7 box then my work's Windows XP machine. Good luck..

The cable I used was the one that came with the phone, what's odd is that I've never had this problem until earlier this week. I've tested it on Win7 x64 and Win7 x86

Tried ODIN 1-click and every machine I've run it on is windows 7.
I haven't had any luck getting a decent connection to my phone yet either. I've tried several different drivers, x86 and x64, different versions of each. Different versions of Kies and Kies Mini. I've tried suggestions from online. Nothing has gotten me anything reliable. I almost forgot, I've tried 2 different phones also. It would be one thing if it just NEVER worked, but for it to work sometimes and other times not, mostly not, is frustrating. I'm afraid to try a new ROM since everything I see about unbricking a Captivate requires a USB connection.
You definitely need to have to have a working USB connection before flashing... and plus you need it to return to stock using ODIN.
Have you tried re-installing the drivers with the phone plugged in and no dice?
I've tried plugged in, not plugged in. USB hub, USB motherboard connection. Just about everything I've seen online I've tried. Some don't work at all and others work briefly but usually within a day refuse to work more than it does work.
Ive tried uninstalling and reinstalling drivers, changed ports, changing computers, USB debugging. everything, whats wrong?
I had similar problems, and did a system restore on my Windows 7 64 computer. Some updates didn't allow the phone to mount.
I'm not saying this is your case, but it's worth a shot.

A little more info would help. What is your PC specs? There are some known issues on Win7-64.
ya i have Windows 7 64 bit
Its Win7 64 I had similar trouble
first try right click Mini Kies run as Administrator, then plug in phone when Kies says to, Windows will recognize it if it has the usb drivers if not it will look for them and will install, then try again ..good luck

ya, i am and i dont know what to do.
Now work shows the icon on my phone but it freezes when i click on it and i have to battery pull to get it back to normal.
Are you on a custom rom or stock? If custom, which rom?
i am on firefly 2.5
Hmm... Well its not the rom. Firefly 2.5 works fine for that. Any chance you've tried a different usb cable? Didn't see that in the op. Could be a bad pin/wire in the usb cable itself or on the connectors.
Also, no dirt/debris in the usb connection on the phone itself right?
Just to be clear the phone will charge when the usb is connected as well correct?
ya ive tried different cables, computers, roms everything i went into recovery with the usb plugged in and clicked mount usb and it works then but i dont want to do that every time.
still doesn't work after a few days

I had a cable issue when I first got my Captivate, and it was incredibly aggravating diagnosing the problem. The trouble was that with my USB cable the phone would charge just fine, but the computer would not recognize it. I assumed it was the phone or drivers--since the cable seemed good. At that point I didn't realize how precise the voltage has to be and stuff for the computer to recognize the phone. I tried my wife's cable, and everything worked fine, so I brought my cable back and AT&T gave me a new one. Not that this story helps you at all since you already tried a different cable...

ya thats exactly whats happening but i have two different cables and they both dont work
Is it all possible to swap cords with an AT&T store? I'm sure it's unlikely that both cords are fruity...but it'd be worth a try if possible.

Hey guys today my second USB port stopped working for ODIN.
The front two on my PC don't work for it and I got 4 left on the back, is there any way to solve this issue?
uninstalling and reinstalling the drivers then rebooting has always fixed it for me. if that isn't working i've got no clue. sorry i couldn't be more helpful i guess.
Yea I know but same problem.
I'm anxiously saving money for a GS2 and Netbook.

also have the same problem with my old pc, two front usb don't work with odin, but work with anything else.
I've had this same problem, and I haven't been able to fix it. But now I've switched to Ubuntu and Heimdall.
I don't know if this will work for you, but this USBDeview looks like it might do the trick: http://www.nirsoft.net/utils/usb_devices_view.html
I assume you are using Windows, and if you are, there is one trick that I have used in the past to fix other devices. This *might* work for you. Try removing the non present devices from device manager. In order to do this, you need to Google how to view Nonpresent devices in device manager. This trick will show you every device that has every been plugged into each USB port. You can then go in and remove the drivers that were previously installed for your phone on that port. Whenever you remove the nonpresent device, next time it is plugged in, the computer will think that it has never been plugged into that USB port before.
Hope that helps!
Im serious about the new cable. I had a problem with the default usb cable before until a friend gave me his mt4g usb and never had a problem again. I think its a data miscommunication with the t959 stock usb. I lost any ODIN connection on all ports until I switched. Try it. Youll see.

That's actually what USBDeview does.
I got the updated version of captivate from att center with froyo with gps fixed. Now two new issues: I rooted the older one and used titanium to back my datas.
Now with new one, I tried to restore two roadblock.
- Windows driver no longer works with this new version. I even removed the drivers from registry still no avail. (SGH-i897_Captivate_USB_Drivers_5_02_0_2.zip)
Once re-install then I choose USB storage version and driver installs but systems can not recognize the device and appears as unknown device in the device manager.
- One click root application can no longer recognizes this new version. This is the app I used to root and unroot the older captivate. GalaxyS_One-Click_Root_All_Models
However, I believe this might be due to the first problem, the driver is not being recognized.
Any help will be appreciated. Thanks,
Try a different USB port

Well well... so I guess I'm not the only one with this "unrecognized USB drive" issue. I too exchanged my old one because of audio jack issue from at&t service center on September 3rd. The GPS is amazing but I cannot mount it as SD card. Tried everything regarding installing drivers. I tried all the USB port available on my system, still no go. Uninstall and removing every single trace of registry. Still no go for mounting as drive. The Max I can do is mount as MTP. But as soon as mount as storage, it pops up saying 'unrecognized USB drive'. I have literally invested more than 24 hrs without any fix. Only good thing about this is that the GPS is a killer. I drove from Indianapolis to Louisville and it didn't deviate even for a second from the route even when I sometime reached a speed of 90mph. If anyone know how to resolve the issue of mounting the phone as storage device without getting the USB error, your work will be highly appreciated.

Try a different USB cable. The one that comes with the Captivate stinks. I had no problem mounting my Captivate on my old computer (which is a Mac), but when I got a new iMac, my phone refused to mount. After several hours of screwing around, I tried the USB cable that came with my wife's Motorola Bravo. Damn thing mounted right up.
If I use the stock Samsung cable, nothing. If I use the Motorola cable, flawless.
Give it a try.

That will work for your situation

It has to be something with voltage. My Samsung USB cable (the one that came with the phone) worked just fine with my old computer. When I upgraded my computer, the cable no longer worked.
I did notice that if I plugged it into a USB hub instead of directly into the Mac, then the phone mounted...but the connection was slow and it dropped all the time, so it was basically unusable.
@guyenxda000...try a different cable before you decide it's not going to work. It actually might.
Okay, I had alternative cable in my car and brough home now i can connect. Now, phone is recognized if I choose kite usb mode, and can access sdcard if i choose usb. but still it is not responding to one-root-click application i mentioned earlier. is it not supposed to work with the newer captivates? if not, anyone knows an app to root it?

First, make sure you're not mounting the phone before trying to root it. Make sure USB debugging is turned on, then plug in the phone and just leave it like that. The root process won't run if you have the SD card mounted. Also, make sure you have the latest drivers. Then run your one-click root.
I used SuperOneClick on mine and it worked the first time. My build is an 1101, so newer phones might not be supported. I have no idea if it makes a difference or not.
Dude thx for ur effort for help. But all ur instructions seem to imply i am doing first time. If u read thru this post i already done successfully with my older version phone which means i must have followed all the steps u described. if u really meant to hlp can u clarify build 1101 u kentioned? If u do that it cn help me someway. Thx
okay lot of progress yesterday, but hit a roadblock.
changed new cable, i had to put the phone into debuggin mode, which I forgot. Now I tried one-click-root app, it does put the phone into recovery mode, but still fails to root saying e-signature verificaiton failed or something.
went through a hard manual way:
copied the rageagainstthecage-arm5.bin into sdcard.
supposedly that should open the terminal emulator in super user mode so that i can mount the /dev/block/st19 into /system as a RW mode, which enables me to copy the other files such as superuser.apk into /system/app folder.
Howeer rageagainstthecage-arm5.bin does not seem to do the job. instruction says after 'spawn child' message restart the terminal emulator which should have turned into # command prompt rather than $. I believe # means enabled to do a root privileged stuff like remounting /system folder. Anyone has hit this roadblock? Thanks,
So I've been reading threw the forums on EVERY phone not just the Captivate on how to get my phone recognized on my computer when I'm in debugging mode/download mode nothing works. I haven't even ROOTED my phone which is why I was trying to get my phone to connect in the first place but I can't even get this far. Maybe rooting just wasn't meant for me.
ANY help will be greatly appreciated whether it be links to something you think I may have missed or actual information regarding this issue.
Either way, Thank you in advance, and happy holidays.
Also more info on what I've tried already, Re-installing drivers, restarting, trying different USB ports.
I'm willing to go back threw these steps if they are different from the ones I have tried before, hell I'll be willing to go back and try it again even if I have done it if it seems to have worked for you or someone else.
Did u see this thread ?... Captivate Connection Issues and Download Mode Help
Yes and although that didn't work, I have gotten my phone to connect to my computer... its just not staying connected...
Does it disconnect when the phone screen turns off? Or is it mostly random?
Bad cable maybe?
Are you using the USB port on the motherboard and not an auxiliary port?
Same issue for me as well. I'm using only ports attached to the mobo. I've tried 4 different known good cables and 3 different machines using the connection troubleshooting tips posted and still nothing. My phone will charge and with go into download mode but only with a jig. I have tried on windows 7 32 bit, 64 bit and windows XP. Also tried out osx with heimdall but still no dice.

Time to boot up the Linux machine. Google wubi installer.
tried again today on a fresh ubuntu install and it cannot detect the device. In Windows I always get unkown device error and now in Linux it just plain doesn't see that a device is attached. I know that the majority of the usb pins on the micro connector must be good because my jog successfully gets it into download mode and I can charge it fine and also getting "unknown device" error constantly. I am at my wits end with it. I took it apart to check the condition of the usb connector and there doesn't appear to be any damage or bad solder joints at all. Just bizarre and extremely frustrating!

What?i never did that and Ubuntu sees both my phones, regardless of the firmware on them. I would think, at most, he might need to install libusb-1 (or something like that).

I will try that as well just so I have using my linux box as an option but I finally did get all of my computers to detect the phone with any of my 4 cables. I got desperate and took apart the phone to see if there were any visible issues with the USB port. It looked as though there was lint or grease between couple of the pins to the board on the USB port so I took a toothbrush and some rubbing alcohol and cleaned it up. I let it dry and reassembled the phone and then much to my delight it was detected! I promptly got it into download mode and flashed back to a rooted stock 2.3.5 with GB bootloader and CWM boog kernel. Phone is so much smoother than it was with 2.1
