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.

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

[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.

USB Driver issues

I've been having USB driver issues for a while now with my captivate (On serendipity 4.2 right now, finally decided to try to get to the root of this issue and update); I've used the SAMSUNG_USB_Driver_for_Mobile_Phones_x86.exe (and I am on 32 bit Windows XP SP3), and have always received a "USB Device has malfunctioned" message whenever I have tried to plug my Captivate in.
My computer has 2 USB Ports; one of them has a USB 1.0 hub plugged in (which has a keyboard & Plantronics Microphone plugged in as well) and the other has a Logitech mouse. I've tried both of the main USB ports, as well as the hub. The hub's been plugged in when installing and uninstalling (I'm trying to give as many details as possible in the hopes that one of these might trigger a red flag).
Anybody know what the problem might be? Maybe I've been uninstalling the drivers incorrectly? (I've done it through device manager & restarting the computer before reinstalling)
EDIT: No Kies on this computer, has never been installed; I have been mounting the device via the notifications menu but it still gives me a malfunction error.

Hmmm.. You've done everything that I would try as well...
At this stage I can't really say it's anything specific... Have you tried it on any other computers by any chance? Or got it working before?

Should mention that I got it working by turning on USB Debugging mode on after installing the drivers, then plugging the device in, and after that it began to function as normally.

So is it working now or not? Sorry, the latest post is a bit confusing...

I think that's a known issue. I usually can not get my computer to recognize my captivate without enabling debugging

[Q] Windows "USB Device Not Recognized" error

Does anyone else have this problem? When I connect my phone to either my laptop (winXP) or my desktop (win7x64) I periodically - constantly, really - get this message:
"One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it. For assistance in solving this problem, click this message."
When I click the message, it identifies my phone as a Generic USB Hub (4 ports) with the first child being a USB Mass Storage Device, the second being the problematic "Unknown Device" and the last two are "Unused Port"s.
This happens whether the phone is in charge-only or mass storage mode. I tried installing the autoplay drivers and that didn't help, so I uninstalled them. No hubs are involved - I've always plugged straight into the tower or laptop. I've also tried two different quality (first party Motorola) cables.
Mass storage mode works fine despite the error - I can access the Internal storage as well as the SD card. Is this a problem with my phone, or am I missing some software on the Windows side?

Have you tried installing the WHQL drivers for this device from here: http://www.lgforum.com/resources ?

Thanks for the suggestion major. I tried those drivers with no luck - the message still pops up frequently in both charge and mass storage modes.

Odd... I had issues with the original drivers, but once installed, I never had another prompt again.
edit: I had it one more time, but it found them and installed them

that's very interesting. i also use 2 machines--one with xp and one with win7. my usb connection worked flawlessly on both. fyi...my connection default is mass storage, and i've actually never tried the other options. i wonder why the difference? did you make any changes? are you rooted? i am not.

Hi gr33nT,
Thanks for responding. I'm 100% stock at the moment, not rooted or anything (though it will be soon ) Sometimes I use charge only if I have it connected to my laptop at work but I still want to listen to music from the SD card. I may see if I can get Verizon to swap out the phone, the message pops up all the time and it's getting annoying...

A quick follow-up on this one: I tried the stock LG cable on my win7 machine (I had been using moto cables). I installed BOTH the bootstrap drivers as well as the LG drivers from the web - still happening. I rooted with these drivers via S1C so I know the drivers are good. If nobody else has run into this, something is probably wonky with my phone, so I'm probably going to exchange it.

For mine, every time I connect, it asks me if I want to install bootstrap. Even though, they have already been installed cuz I am rooted.

I've had the same issue both as stock, and rooted and in every configuration with the phone and PC you can think of. I've downloaded the drivers and installed them from both the phone and web site all to no avail. This is really getting annoying.
I hope someone has a fix for this.

Hmm...that is troubling. I'm still having the issue running the stock rom and rooted, now. When I get time I'm going to drop by the Verizon store and hopefully they'll replace the phone - I suggest you try the same, as I doubt it's the computers we're using. My win7 box and winXP work laptop could hardly be more different!

I doubt a replacement will fix anything, I experience the same thing as majorpay. Drivers worked for a while and then it started asking for it again. This also causes issues when using usb tether as its connecting and disconnecting. The issue is not present when used as a mass storage device.

Hi bwhxeon,
The issue (USB device not recognized - it sounds like you're referring to the autoplay driver installation) happens for me in mass storage mode also. I believe it has to be the phone as I've never had this problem on any of my PCs with my OG Droid or any other USB device. With this phone, I have the problem on all of my PCs.

I had the same problem. The error popups seemed random at first. I noticed if I enabled/disabled the WIFI on the device while it was connected, I could make the error popup.
I ended up getting a new replacement device when I also noticed the 4G Hotspot wasn't working either even after a factory restore. There was definitely a hardware issue with the phone.

USB Unknown Device
same issue here.. when using ADB though I have to set to Internet Connection then it goes away for a while until I want mass storage or just charge from USB again, then re-appears.

LG is not like most other phones as in usb debugging only works in internet connection mode where others go into it as soon as you plug it in.

Just kind of scanned this thread but have you tried a different USB cable? I was having a problem with mine only wanting to charge with the stock so I grabbed another cable and it has worked right ever since

Same issue, two different pcs, with two different cables. Bootstrap does not load anymore so I am using the drivers from the links, both sets of Lg verizon drivers

[Q] USB Device not recognized

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.
