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

[Q] Can't connect my Captivate through USB anymore

Hi everyone,
I'm having issues connecting my Samsung Captivate to my computer. For about a week, it worked fine, I was able to transfer files to my phone but recently I noticed that the "USB connected" notification is not showing on the phone when plugged in to the computer.
Now, when I plug in my phone to the computer it just charges but doesn't comunicate with my computer. A friend of mine bought the same phone right after I did and he gets the "USB connected" connected when he plugs in his.
I tried using his USB cable but again, the phone is not recognized by Windows nor the phone detects it is connected to the computer. I've tried installing several USB drivers that I've come across on several forums, but nothing. I even downloaded and updated Kies to the latest version, but still nothing.
My phone is unlocked and NOT rooted, and I'm using Windows 7 x64. I've set the USB Settings to Mass Storage, even to Ask on Connection, but it doesn't ask anything when I connect the phone to a USB on my computer.
Sometimes Windows knows there is a device connected but says it couldn't recognize it.
I already did a factory reset, but the issue was not solved. I've tried connecting it to other computers, but still hasn't been able to connect my phone correctly.
What could it be?
Thanks!

Hmm. You have Mass Storage selected and up-to-date USB drivers. Try selecting USB-Debugging and Stay Awake in the Development option of your phone. If that doesn't fix it, then I have a few other ideas.

Make sure the usb door is completely open, it should click into place, some users have reported this solves their usb issues.

I did what you told me, but still my phone ain't recognized by Windows nor my phone is aware that it has been conected to a computer
What other ideas do you have in mind?

Have you tried using a different USB outlet on your computer? I had this same issue when I plugged my phone up using the USB outlet on the front of my computer then when I tried the one on the back of my computer it worked just fine.

Are you running a launcher app? I use launcher pro and can't connect until I change back to the default launcher with home switcher and launch it.

First off, think back. If it worked for a week and then suddenly stopped, what changed? Maybe you updated something on Windows or changed something on your phone. There's a reason it just stopped.
You can try using a free program called USBDeview.
It might do the trick for you and help you install the correct drivers. I'm thinking you no longer have them.
1. Download USBDeview (link is above)
2. Plug your phone in and open the program. Find all the HTC drivers-delete them
3. Unplug your phone and plug it back in
4. The correct drivers should install automatically
You can also try updating the drivers manually.
Galaxy S drivers (These are for ADB, but will work fine)
1. Click the Start Menu on your computer and right click "Computer"
2. Choose "Manage" --> it will ask you to continue --> "Device Manager"
3. Plug you phone in and look for it to pop up, probably under Portable Devices
4. Right click --> "Properties" --> "Update Driver" --> "Browse" --> "Let Me Pick" --> and navigate to the location you extracted the drivers to.
This is most likely a driver issue. I doubt your phone is messed up. You'll get it eventually. I also had a hard time getting my Captivate to connect. After uninstalling and reinstalling my drivers (more than once) it finally worked. One last thing, for now. When you uninstall drivers, also make sure you don't have any installed under your program list. As in, Control Panel --> Uninstall a program. Good luck!

A friend of mine, who bought the same phone on the same day as I did, plugged in his phone on my computer using my cable to the same port my phone was connected, and he did get the "USB Connected" notification on his phone

I did all that yesterday, but the device ain't listed in the USBDeview nor it shows up in the Device Manager

did you finally fix this problem? because I'm having the same issue here

Same here. It was working fine, I could connect to Kies, transfer music in Media mode and see both sd drives in Mass Storage mode. Then I rooted today and now I get nothing. In anything but Kies mode I get the Windows Bong of Recognition, but still not visible in Explorer. Also, my Home screen stays active instead of switching to the USB animation like it did before. I know this can't be a consequence of rooting the phone, can it?
EDIT: More weirdness, with the phone connected in Mass Storage mode if I look at My Computer in Explorer there are 2 extra drives showing, but they are greyed out and when I click on either of them it asks me to insert a card as the drive is empty. WTF???

UPDATE: I unrooted and managed to get my USB connection back to working. It is still a bit flaky as I sometimes have to disconnect/reconnect several times before it works, but at least it now works although it sometimes loses sync in the middle of transferring a file. Can't imagine why simply rooting the phone would cause the loss of USB connectivity. I am going to reroot and see if it occurs again.

OK, a rerooted the phone and this problem is now back. I have no problem connecting while in debugging mode. I installed OCD (non-Market apps mod) and when I turn off debugging and connect I get the Windows bong and see the USB icon in the Notification bar, but the MTP screen never comes up and I can't see the phone in Explorer (Mass Storage mode) or in WMP (Media mode). Kies can;t see it in that mode, either. I really don't want to have to unroot every time I want to look at the phone contents. Any ideas? PLEASE!

I'm having a similar problem - I installed the Perception ROM and immediately afterwards I can't see the USB connection at all from my PC or my Mac. The USB icon on the phone does not come up either.
I'm trying to get my hands on a different cable - but the weird thing is when I plug the USB into my computer the phone starts charging for like half a second and then stops.
This is really annoying. I tried changing the rom to Cognition 3.02 but that didn't change anything.

There are a few topics on this here on the forum - I would recommend the following:
How are you rooting your phones? Nobody has said exactly how they are doing this. Are you using recommended rooting methods? Or are you using some app found on the market?
Make sure you have USB De-Bugging is turned on.
Make sure you have it listed as ask on connection.
For those who can see the drives in Windows...
Plug in your phone and then pull down your notification bar and click on the USB connected message. It will give you an option there to mount your SDCard(s) to Windows allowing you to transfer files.
Kies is junk - I'd recommend uninstalling it as it seems to cause more issues then it solves.
Use the drivers I have posted in the Q&A section (these are the ones that are linked in Design Gears Odin 1 Click Back to Stock post btw) - but I would try and COMPLETELY removing the pre-existing drivers before installing the new ones.
Make sure the USB Cable is plugged into the back USB port that is directly on your motherboard - this will ensure it's not a computer/hardware related issue.
I know of one user who had to go through his computer and manually remove all remnants of other drivers. I have my phone connected to both a Windows XP 32bit and a Windows 764bit systems and have been lucky to not have any USB issues.
If none of that works - I'd suggest taking it to your nearest AT&T/Rodgers shop and see if they can get the phone to connect (make sure it's back to stock!). If not they should warranty replace the device.

This isn't my first rodeo... But to answer your questions:
I used the rooting method posted in XDA forums - the one-click rooting.
I've used the drivers included in the xda-forum. Not the kies software.
The only thing that changed was the loading of a new custom rom. The cable works (confirmed on my friend's phone). I can't get odin to restore back to stock because I can't get the computer to recognize the phone in either normal or in download mode. I've restored to stock using the jh7 in the stickied q&a thread
I don't think it's a hardware issue either - I think it's software-based. I'm going to try to take it to an at&t store today at lunch to see what they say.

I also have that problem only I noticed it when I cleared the dalvik cache. It messed up the auto rotate so it was always sideways and now I have no connectivity to the PC. Let me know how ATT treats you.

[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?

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

Sorry, should have mentioned this. Yep. I have. I've not been able to see it in either environment (currently running win7 on the machine I'm typing on). The last time I was able to see it was on an XP machine. Never on Vista and now on this new 7 box. I have also factory reset this as well but still nothing.

Made me LOL...
Turned it off. Connected to PC. Selected mass storage, then the option to mount. Then got the USB device not recognized message again as well as the option to look at the USB device properties which indicated the unknown device and to "replace the device if windows is unable to recognize" it. I also opened kies express which I also downloaded to load the most current drivers (for US). Still nothing.
If the wifi didn't work on it, I'd probably take this thing skeet shooting and use it as a clay pigeon, I'm that frustrated...

Deinstall all program including drivers and kies. Reboot and in system/config look if their is all cleaned so no Usb installed
Now reinstall kies.
On your tab in system connect to kies on connect and not to Usb.
Now connect tab to windows and only when no connect is fossiele then install usbdrivers.

Ok...completely uninstalled everything and checked the registry for any instances of Samsung to make sure all drivers are removed. The only difference now is that I couldn't find the link to Kies Express, so I'm just going to install standard Kies. Crossing my fingers.

The tablet shows connected to Kies when that is opened but when I close that and try to connect as USB and mount. I get the same error message about USB device not recognized. I also try to update the driver in system properties but get the same error that the device driver is up to date "unknown device".

Windows 7 is automatic. On the dialer type *#7284# and set usb to pda.

maybe your usb cord is fudged

Yeah, thats a good reminder. The aftermarket cords have caused a few temporary bricks.

Vista trouble
my experience is trouble to connect kies gtab while i'm having my portable hdd with my laptop

Oooh, thats a good point too. Disconnect those other usb devices when flashing your precious! And all usb ports are not created equal. Only one of the three on my laptop recognizes my tab in odin or heimdall.

I spent a couple of days trying to connect my Tab to a number of different OS's from XP up to Win7 on 3 different computers. Each time the dreaded message of "USB device not recognised" came up. The solution was so simple after all the frustration. Soon after purchasing the tablet, I bought a car charger which came with a connection cord. Looks the same as the original except without the the Samsung logo on the flat connector. As soon as I plugged in the original USB lead, voila! "Device is ready to use" message appeared.
Moral of the story. If you are having problems connecting your Tablet to a PC through USB..... make sure you are using the USB lead that came with the tablet.

[Q] Computer doesn't recognise Touchpad in USB Mass Storage Mode

This is kind of strange. I have a 32gb Touchpad and Win 7 32bit computer. Upon first use of the Touchpad, I followed the guide posted in the tweaks and tips section right away.
I updated to 3.0.2, turned off/down logging settings, installed Preware, installed all of the recommended patches, installed Uberkernal and Govnah, and OC'd to 1.5mhz.
I then went to load some media (songs, videos, ebooks etc.) onto the touchpad by connecting the usb cable to the Win 7 machine. The computer makes the found new hardware sound and the touchpad then asks if you want to put it into USB storage mode (which I did). The computer should then pop up with the window of the Touchpad drive and assign it a drive letter (just like any other usb mass storage device), but it doesn't. when I go into windows explorer, it shows a new drive letter has been added, but when I click on it to presumably see the contents of the Touchpad's drive, the computer does nothing. In fact, it even caused Windows Explorer to stop responding.
I almost positive this is a Novacom driver issue, but that doesn't make sence due to the fact that those drivers should (and were) loaded when installing Preware.
I am not sure how to resolve this. If anyone has any suggestions, they would be much appreciated. Regards, Dcartes-

I'm have a similar drive issue but it consist of the touchpad (I think), not recognizing when I disconnect the drive via the computer. This always results in that error message stating that I didn't safely remove it after I physically unplug it.

I'm not sure on the OP's question but as for the quoted response you need to go into my computer and right click the touchpads drive letter and then choose eject..
simply unplugging or using "safely remove hardware"will result in the error you are seeing

And if I connect TP via USB and then disconnect it w/o PC "eject" thing, then next time PC wont recognized TP in USB mode. And I have to restart TP to make it "recognizable" again

I go through all the normal, safe, and necessary steps but no matter what the tp always stays connected. I've even went so far as to shut my computer down completely with my tp still connected and it still stays in disk drive mode.

I've had to same problem--finally tracked it down to the original usb cable. Touchpad would still charge but was not recognized by the computer. Changed to the cable that came with my Samsung phone and everything works like a charm.

Ouch message when ejecting

Thanks for the tip about the cable. I had the "Ouch That Hurt" message the other day after moving some pictures from my PC to the Touchpad and then ejecting the Touchpad. Ejection did not work. After the ejection process, the TP was no longer an option with either of the normal methods for ejection. So, my PC thought the TP had been ejected. But the TP did not think it had been. So, no option left but to turn off my PC or unplug the USB cable from the Touchpad to the PC.
However, I have noticed an issue with charging the Touchpad lately where I have to wiggle the cable where it connects to the Touchpad to get it to charge properly. Could be that this same flaky connection gave me a problem when trying to eject the TP after transferring the picture files? Though the pictures DID transfer properly. Will try a different cable next time. Hope I don't get a "wrong cable" message when doing that. Hate it when the TP does not eject properly as I fear I may be introducing file errors when that happens.

the only way to eject is from MyComputer > right click HPTP > eject.. or it will complain..not from the tray icon
ppl will bet that your prob is cable..
i went to national electronics store, they had phone section w/ many cables and phones plugged in..
i tried their cable to my HPTP and my cable to their phones...
cable was for sure bad.. they wanted 20$ for a 3' cable.. too much..
amzon wanted 4$ for set of 2 @ 10'..+ free s/h..
guess where i bought from..
