Hello,
I am newbie here.
I have my captivate since January. I like the device itself very much.
However, I wasn't able to update the firmware to Froyo or Gingerbread at all due to a lot of difficulties that I faced.
My phone is ROOT(just to confirm, I have 'superuser' app - does that mean my phone is ROOT?).
I used to have laptop with linux 10.04, and believe or not it was so difficult to ROOT my phone.
However, I have Win7 64bit Professional currently.
And trying to upgrade to Gingerbread. (My phone is 2.1 firmware as of now.)
The problem that I'm facing is that my phone won't recognize at all when I plug into USB ports.
These are what I've tried so far,
(on both USB debugging mode & mass storage mode)
- Yes, I tried several different ports as of suggestions from other post.
- I tried to install & re-install drivers. (I tried SGH-i897_Captivate_USB_Drivers_5_02_0_2.zip driver & Samsung Galaxy S USB Driver for Windows x64)
- I did restart my computer more than 10 times.
- I installed current kies and re-install several times.
- I installed older version of kies 1.xxxx.
- I did delete drivers from device management.
I am really running out with ideas to solve my problem.
I've been researching a lot & can't find any more solutions.
CAN ANYONE HELP???
Thanx!!!
Have you tried a different USB cable? Preferably the one that came with the phone (unless that's the one you're using now, of course)?

The cable that came with the Captivate is known to not work with all computers (my guess is it's some sort of voltage range it doesn't like). There are a few threads on this in this forum.
My suggestion is to get a Motorola cable. Here's why:
My stock Samsung cable that came with my Captivate worked on my old PowerMac G5, but not my brand new iMac. I thought it was an attempt by Apple to deny use of Android phones on their machines.
I tried using a store-bought USB cable by RocketFish. It still didn't work.
Out of desperation, I tried the Motorola cable that came with my wife's Bravo, and the phone connected with no problem.
From your description, it sounds like you could connect on an old computer/OS combo, but not with a new computer/OS combo. So try to get your hands on a Motorola cable (or other third-party cable) and try that.
@ apbthe3 yes, I am already using the cable that came with the phone. Thanx!
@ KreepyKen I did try the cable that I have with on a mac computer and the mac seems like not recognizing either. I'll go to AT&T shop to see if they can try with motorola cable. Thanx!

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

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.
Current Scenario:
Phone is stuck at AT&T screen. Can get to download mode. XP cannot installing drivers.
Questions:
Has anyone encountered anything like this? I know some people report issue with some data cables not being able to connect. But I am surprised I can get to download mode with it so am questioning if the cable could be the issue. Could it be a bad port? Since my original cable has gone bad could it have messed up my port? I saw a posts about this but no follow up.
Notes:
Cognition 2.3b6
USB Drivers from (http://forum.xda-developers.com/showthread.php?t=731989) I've obviously have been able to connect prior to these issues to upgrade my ROM.
Kies and Kies Mini were previously installed. I since deleted since having these issues.
Uninstalled iTunes as suggested in other posts.
History:
My phone is stuck at the AT&T boot screen. Using my original Samsung cable I could not get my phone into download mode. So I went out and made the jig to get it into download mode. This worked but win XP won't recognize the phone once I put my original cable in. I realized that my original cable might be internally frayed, so I went out and bought a generic USB cable. Now I can get my phone into download mode (without using the jig) which shows that my original cable has been damaged at some point. This would also explain that when my phone is off and I plugged it in using the old cable the phone would turn on.
Anyway, using this new generic cable, XP/ODIN won't recognize my phone. When trying to put it in download mode (two button/insert cable/no SIM/no SD), I see XP popup: Found New Hardware, USB device, Samsung USB Composite Device, USB device, Samsung USB Composite Device, then get the Found New Hardware Wizard with message Cannot Install the Hardware, problem installing this hardware: USB Device.
Thanks in advance.
Oh and not sure if it matters but I cannot get into recover mode either. Cannot get past AT&T boot screen.
Um... make sure you remove all traces of the Kies stuff.
Re-install USB drivers over the top of the existing ones.
I might suggest buying a "sumsung" cable from an AT&T dealer.
AND - make sure your using the USB port that is on your mobo - apparently it makes a difference.
I had my phone in a "bricked" state and had to re-install drivers on my Win7 box. it found the phone and recognized it enough for ODIN to start up.
Also.... to find out if the phone is being recognized - I would recommend d/l'ing the Android SDK and doing the ADB command - adb devices and see what pops up.
Heh - last thing.. please say you had the phone in "USB Debugging" mode before things went south?
Here's a link to a thread containing another variant of the Captivate USB Drivers:
http://androidforums.com/captivate-.../123644-captivate-usb-drivers-links-here.html
I can't remember which I used, but if the above suggestions don't work for you, it won't hurt to try these!
And for what it's worth, I don't believe the problem to be within the USB cable. I use everything EXCEPT the Samsung USB cable. Anything from Monoprice.com cables, to my old Blackberry cable... A MicroUSB cable is just that...generic or not. As long as it's a 5 pin cable, you should be good.

Called AT&T said they didn't carry any data/sync USB cables. Which I found was odd. Have one coming from Amazon soon that looks-like and is listed to be OEM.

Upgraded to Cog v2.3b6 before things went south. I normally keep USB Debugging mode as defaulted. Wondering if the update would have caused it to be unchecked. I think I checked that once and rarely make changes. Either way, are you suggesting that if that option is not set that I am pretty much hosed?
@norcal einstein: I will have to try your suggestion from a new machine. My work just locked (McAfee) our machines due to virus going around.
Hi there ... I've run into this similar problem before.. The link you posted's instructions:
"plug usb then open odin"
NO!!!!
#1 odin oneclick must be open before you connect your phone. (and i didnt see in previous posts that you did this?)
Here's the rest....
From a soft-bricked state the Samsung I897 displays a "gadget" screen involving
icons of a phone + exclamation + computer. It is still possible to boot into download mode from this point (which is before the att logo) there your phone can.
Apparently you've been able to get into download mode .
When my phone was soft-bricked and I finally figured out how to put it in download mode I got the "gadget serial device driver not found" bs. I had already opened odin-oneclick and it said "added". So I tried and it worked.
There is no better source for drivers than the manufacturer. So i suggest using those drivers instead. Also the usb port on a captivate IS a generic usb plug.... it's just offset to the side a little bit to add STYLE.
Thanks to everyone that replied. I just want to provide a my resolution for others that might be search for similar issues.
My Captivate is now back up and running. Loaded with Cog2.3b6.
The generic cable proved not to be the issue. I know some people reported having issues with cables but I believe as long as the cable is labeled to be a sync or data cable you should be fine. Avoid the charger cables as it will be just that - a charger cable only.
The jig worked like a charm to get to download mode. Just connect the two leads (4 and 5; closest to the center of the phone) using 301k resistors worked. I used 3x100k and 1x1k. Although, I later learned that my OEM cable went bad on me and just getting a new cable I can get into download mode fine. If some of you are having issues might want to consider keeping a extra cable just to rule out cable issues before trying out the jig. The jig IS very easy to do but finding a micro-b USB plug or adapter that gives easy access to the 4 and 5 leads might be hard.
Out of ideas what was wrong (being stuck at AT&T boot screen, being able to get to download mode, my laptop not being able to detect my phone) I borrowed a laptop running Vista. This worked! Vista and ODIN detected my phone and I was able to get back to stock.
So still not sure what's wrong with MY laptop. Hoping to get it resolved by the time they get the AT&T Froyo update out. But I am very much guessing our tech department tightening up McAfee restrictions (like being able to download exe(cutables) might be the culprit. I will have them remove the restrictions so I can re-install the USB drivers and see if that works.
If you are looking for instructions for how to get download / ODIN working, all the instructions from all the many threads work. I will not repeat those instructions here. But a couple notes: I didn't find any difference with leaving SIM card in or out. Might be best to just leave it out. I've tried both inserting cable last and inserting battery last. Both ways works. So if you can't get one way working chances are you probably won't be able to get it working the other way either. I personally use the battery first, both volume buttons then cable. Once I had to wait 10 mins before getting it to work. That was probably once in about 10 times I've done download mode.
And BIKERBOY8989 is correct, if you can get to the AT&T boot screen chances are you SHOULD be able to get into download mode. Might want to check cables and/or try on another machine. As I mentioned already.
Good luck!!!
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?

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..

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.
I'm running Winxp SP3, Captivate with Cog2.8b3
I had installed the USB drivers for 32bit provided on these forums (before connecting my phone), then connected my phone and had windows throw up the "usb device not recognized" message. There's no android/samsung/etc. listing under the device manager.
Anybody else had this problem, or know how to fix it?
I had similar issues and reinstalled and uninstalled everything multiple times and that didnt fix anything. My suggestion would be to try a new USB cable or each of your USB ports.
My cable that came with my captivate was actually bad. It would charge the phone and even attempt to register with Windows by eventually fail with the same error you listed above.

I've tried each of my ports; the cable had worked previously, fairly recently, but I have a new windows install. I'll try a new one when I get back from school.
Try removing all bits of the USB Driver after un-installing them.. then try re-installing. XP is a pita with USB devices sometimes. Well windows in general for that matter.
If anybody could help that would be great. I'm trying to return to stock and use LGNPST to flash a .tot file. However, I have discovered I cannot do anything with my phone on a pc. I've tried several different cords; to be honest I have no idea if I still have the original cord anymore. I have too many cords and not sure which phones they came with, however, it never mattered in the past, I originally rooted using a cord from a Samsung phone. Most cords the computer does not even detect something plugged in to USB, but one cord it says device not recognized. I've tried this on 2 different windows 7 machines and my apple, I've uninstalled and reinstalled on USB drivers manually and still no luck.
Only thing i've noticed is that when I use the one cord, the computer tries to reinstall drivers automatically but the phone reboots, computer says installation failed, then USB device shows at not recognized. However, as I said I've manually installed drivers from LG website. And I cleared all USB drivers and reinstalled them.
Any suggestions? Thanks for any help or suggestions.

imho, I think it might be a windows thing. I have issues with windows 7, I can't get the pc to see the phone. I have win7 64 bit. But xp 32 bit on my wife's netbook works like a charm. I would suggest trying a different version of windows. And I can use my sammy usb cable for just about anything dealing with the revo except flashing a tot. The flash errors out at about 19% with any other cable besides the lg one.
