Ok I know this problem has been highlighted several times but I cannot get to the bottom of this...
I'm having problems when the phone is connected to the PC. This only started happening after I unlocked my bootloader. When the phone rebooted after this, the phone made the noise that it was connected to the laptop, followed by a disconnection sound a few seconds later with a message that the MTP device driver could not be installed. I am using Windows 7 x64. Prior to this my phone worked fine with the laptop
After this, I uninstalled all the drivers including HTC sync followed by a restart
I reinstalled all the drivers - still didn't work
I tried 3 different USB cables - still nothing. I also tried these all in different ports
The phone registers in bootloader as fastboot usb. Once in recovery adb no longer works and the device disconnects again
Anyone want to shed some light on this? It happened me before and it somehow seemed to rectify itself
Anyone help me on this?
Tried 5 different USB cables. Also tried on another laptop with windows 8 installed. Still no luck. One of the USB cables charged the phone but did not register under device manager and ADB still did not work...
I am completely at a loss as to why it is doing this
Also, when I connect to a charger, the Car app opens....so I think it may be a voltage problem...

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
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.
It has just stop working when a plug in my usb to my pc i do not get "Turn on USB storage" on my phone. No usb icon also. The computer does not recognize the phone.
I have try different cables, computers and OS. Also did a factory resat and putt on debuging mode on and off. Also multiple restarts with no luck. I use stock rom.
Are my phone broken?
It's probably the usb ports though you have tried with other computers ;/
or the micro-usb port of your device

I had the same problem and I believe it is a phone issue. I tried reinstalling drivers, different USB ports on different machines, factory resets, different cables etc. At times when plugged in the phone would suddenly wake up and acknowledge the USB connection while at others it just started charging when plugged in to USB.
What confirms that this is a phone problem rather than a PC problem is that when I connect it to my office workstation that runs on Sun Solaris, it behaves pretty much the same, acknowledging the connection randomly. My HTC Magic on the other hand always connected to both home PCs and office workstation without any issues every time.
Finally I have returned my handset and asked for a replacement.

I have returned the phone to the store. I will have to wait two weeks if they fix the problem. But thanks away

Good luck. It's a pity though as otherwise my handset worked perfectly with no reboots lags etc. I hope the replacement comes in soon and is bug free too.
I have the same issue with my macbook. Since yesterday my o2x isn't recognized by my mac.
I know it is not the usb cable, or the (micro)usb port, because when i plug the phone in at night my alarm clock on the o2x fires up (as it should).
So a connection is made, it just doesn't show "turn on usb storage" on my o2x. And i cannot understand why.
I am on the 0606 baseband, with the new FR19 ROM from Paul O'brien's Modaco (which is excellent btw).
If anyone has a solution, please let me kno
I have the same problem with my phone under modaco fr19, baseband + ril 606.
My pc is under windows vista and the drivers are installed correctly.
Awala
Update:
I received a replacement handset which was V10D 20110405 out of the box. No issues with USB connection.
Just out of interest, did any of you leave the phone connected to USB for a long time before it started failing? I used to leave it charging via USB all day at work so just wondering if there is a connection...
Update:
I earlier stated that my O2X wouldn't connect to my macbook. Yesterday I connected the O2X while on the Windows Vista partition of my mac, and it connected without any problem. After that, rebooted to Mac OSX partition, and no problem there. So I am a bit puzzeled about why, but it seems to work again.
In reaction to mparack's question, i sometimes let it load overnight via usb cable. But not a lot. I do not think that was the cause. I thought it was caused by flashing the 0606 baseband, but now I do not think that was the culprit.
Got back my phone from Telia on Wednesday. Everything worked fine. And I upgraded the phone using the LG update (Basbandversion: 1035.21_20110622) LGE version LGP990-V10c). After that the same problem! It feels like it's a bug in the software. Then they have changed the mainborad and it sounds unlikely that the new one is defective to.Goning back to Telia on Monday if they know about a bug or if you can get a new phone.
Those of you who have had the same problem what version do you have? Can I downgrade phone in anyway?
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.
Hi guys, so I have a little bit of an issue! I've had my nexus 6 for about 3 months and i'm not sure when it happened or why but some how and some way no matter what rom I'm running, USB connection to desktop no longer works. I have tried turning adb on and off, reloaded drivers, and tried other computers. When I monitor device manager in Windows 10 no new devices are connected at all, just does not show up. No unknown device, adb, USB, nothing. So I'm not sure what I should do, I was thinking of claiming warranty however trying to avoid it. Any suggestions??????
P.S: Mounting external storage devices using otg is successful.
May there be some problem with your cable. Try different cable on all available usb port.
I've done that, no success
