ADB device offline

I've been using ADB the last couple of days to install apps on my Captivate and all of the sudden it stopped working today.
When I type 'adb devices' the phone comes up right away, but it shows offline.
I have tried reinstalling the drivers and Android SDK, but no luck. I've searched around and found some others with this issue, but haven't really found a fix that works for me.
Any idea why ADB would just stop working like that? I even performed a factory reset of the phone and put everything back to defaults.

Ok I almost pulled my hair out, but I found the problem.
For some reason, ADB does not work with the Samsung USB cable that came with the Captivate.
I switched to another USB cable and it works just fine.
Man, I really thought I was going crazy.

What the hell is that about!? I wish all these companies would stop trying to break from standards by proprietizing common cables.

I can't get the drivers to work. Where did you get yours?

Yeah I buy that, I couldn't even get the thing to try and connect at all with out switching usb connections on my computer.

stock cable works. I just rooted and ran into that problem. In order to get around it if you cant get a diff cable, make sure that b4 you connect your phone to your pc you turn off your internet so it doesnt auto dl the drivers. b4 u connect, dl the drivers for your phone from the root thread. Plug your phone into ur comp with the internet off and close any pop ups. Go to device manager look for the notification labled usb or captivateand right click and select update. Select search from file on disk or select file (something like that, i forget) and scroll and select the folder where you extracted the usb drivers. Make sure the checkbox that says search subfolders is checked and click next to install. two more drivers will pop up in device manager after u install the first one. Repeat the same procedure for both of them and then you should be able to use adb just fine to root.

Just wanted to further confirm that using a different microusb cable works! I keep reinstalling the drivers but it kept showing the device was offline. Then I tried my old Nokia N85 cable and it worked like charm! So weird how usb cables aren't made equally, unless Samsung designed the cable to prevent using adb?

I had this issue for a little while, but I installed the Samsung Kies software (which contains drivers) and uninstalled the ADB drivers I had originally downloaded. It's worked like a charm since then.
Go to SamsungApps.com and then use the canada site, as the software isn't really available in the US yet.

I have had no problems using the stock cable on my Laptop and work PC, both are Win 7 32bit. The same cannot be said for my my main home PC which is Win 7 64bit. Neither the stock cable nor an after market cable worked with ADB.
For the 32bit OSes I installed the Kies software and the usb device gets installed correctly. for the 64bit OS, I installed the Kies software but could get the phone to connect correctly. I then tried to install the 64bit drivers that are floating around the web. The 64 bit drivers worked enough to get the phone connected to the PC but when I tried to query "adb devices" the phone would always appear as offline. I've tried several things: install/uninstall drivers and software on the PC, restart the PC and Phone, change cables. Nothing seems to help on Win 7 64bit.
It seems to me that there might be a bug in the 64bit driver, though I have no proof of a bug.
I am going to keep playing with the 64bit OS until i figure it out or get so annoyed a that I just give up.
I'll be using my Win 7 32 bit laptop until I get the 64bit PC to work.

i've been able to install .apk's with my win7 64-bit ADB :O
all i did was install Samsung Kies.
i don't think i've ever had a problem...?
EDIT: i'm using the cable that came with it and no problems yet.

I'm running win 7 x64 and Kies did the trick for me. I haven't had a single issue connecting my phone since I did that.
Sent from my SAMSUNG-SGH-I897 using XDA App

Justa dding to the anecdotes.
I was having problems with the included cable using the front USB. It would show as Device Offline, also the charging wasn't very strong.
I switched to the onboard USB at the back of the case, and adb worked fine with the included cable.
Looks like I'll be picking up a couple extra USB cables so I won't have to continuously do the desk dive everytime I need to use it somewhere else.

1. I installed the kies drivers first and it would say offline when i checked the device through the cmd prompt.
2. I then installed the adb drivers and it then said the device was online.
3. i then rooted the phone and went on my way. i then tried it a second time and it said device offline.
4. nothing changed during this time except that i turned off debug mode, changed it to mass storage and plugged it back into the usb to transfer some files.
5. on returning to debug mode it no longer tells me the device is online. i have tried different USB ports as well.
6. i deleted the drivers, and reinstalled and it still says offline.
very frustrating.

wow. i forgot to try plugging it into another USB port. that worked. sorry about previous post.

I am running Windows 7 Home Premium 64bit on my laptop,
I installed the samsung 64bit drivers, it was an installer i found on the web, not the kies installer packaged driver one.
i changed my setting on my captivate to Mass Storage.
I mounted usb and everything works, by that I mean i was able to ADB like no tomorrow without any issues.
Then I made the mistake of installing Samsung Kies and that messed up my previous drivers and I wasnt able to ADB to my phone. I had to uninstall Samsung Kies and my phone still wasnt being found I still couldnt ADB.
my solution to fixing was restarted my phone and computer, without my phone connected to USB i re-installed the Samsung 64bit Driver Package, then hooked up my phone made sure Mass Storage was selected and Mounted USB and bam was able to ADB again.
hope this helps! also i have been doing videos helping people with issues with samsung's captivate on youtube, youtube.com/johnnyzappone if anyone wants to check em out, if anyone has any suggestions please let me know and id be happy to release a video!

I resolved my issues, I plugged the stock cable into one of the rear usb ports and the device is now available on my main PC Win 7 64 bit.

Confirmed this made my device stop appearing as offline with adb.
How it is even possible that the cable prevents (only) adb access on the PC, I have no idea.

I have windows 7 and mac osx and I can use adb with both using the stock USB.
i have debugging active.

lol @ the samsung cable.
i've 2 indentic cables here, one doesn't work. plugged in the other one and this one works...
maby its just a strange issue on windows, next time try to pull out the cable and put in back in then connect your device again this should work.... :s
because earlier the cable just worked fine and now it doesn't.. so good luck xD

also can confirm PITA

unable to connect USB

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.

[Q] Device not recognized?

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.

[Q] Driver Issues? Or maybe cable?

So recently I soft-bricked my phone (phone---!---computer) and it won't go download/recovery. It randomly froze while odin was running. But anyways, I've been trying to use http://forum.xda-developers.com/showthread.php?t=1153310 to unbrick it but it keeps telling me the drivers are not installed.
I've installed drivers using kies, the one click unbrick, and just from the samsung website and none of them seem to work. When I plug my phone in, it makes the usb plug in noise, then an icon shows up in the bottom right task bar for maybe 1/10th a second and then disappears. I'm running vista x32. Any ideas? Could it be the cable?

Heimdall uses special drivers.

As part of the heimdall one-click operation, it should ask you if you want to install the drivers (zadig.exe, I believe, is the application that does this).
If, for some reason, it doesn't, grab the full Heimdall package (search in the Development section for "Heimdall"), and that will definitely have the drivers.

Yea it told me to install the samsung usb composite driver and I did that. After rebooting my computer, when I plugged in the phone, windows confirmed that I had the driver installed but for some reason when I plug my phone into the usb it only recognizes the phone for a split second.
Edit: Actually the instructions tell me to put my phone into download mode in order for the driver to be installed successfully. Since my phone is bricked, I can't do that but it let me install the driver anyway. So I guess that's why it tells me drivers are not properly instaled.

That does sound like either a flaky cable or a USB port that's not behaving. If you have multiple USB ports, try plugging the phone into different ones. If you're on a desktop, the ones in the back are usually better. You may need to reboot the computer between tries.
If all that fails, see if you can get your hands on a different cable, or even a different computer.

Yeah, I would have to agree. People don't realize how much havoc a faulty cable can cause.

I ran on it on my roomate's ubuntu computer and it worked instantly! Thanks for the suggestions!

[Q] USB Doesn't Recognize with all drivers and method.

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!
