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

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.
Anyone else getting this problem or know of a solution. I've updated USB drivers from both T-Mobile, Samsung and utilized Kies Express but still nothing.
Thank you in advance.

Is USB Debugging enabled?
W-7 will be automatic, with the drivers built in, but not vista. You will have to install them.

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.

I have Win 7 and it wasn't automatic. I'm pretty sure you need to install them, either by installing Kies or just installing the Samsung drivers.

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.

Mine is Windows7 64bit Home Premium and it is recognised.
I installed PDAnetA300x64.exe to get the drivers
TC
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!

I am not sure when this started. I have used windows to install cymod several times but i went to download a update and install it and my computer will not recognize the touchpad. it says the device driver was not installed properly
i have tried on two different units.
one has web os only and the other has android
it goes through the steps of looking for the device and then nothing.
i get a tone on the touchpad and then nothing on the computer
I do have the correct setting in the storage settings so i have no idea what to do
did you run novacom again?

It sounds like driver problem to me. Search for HP touchpad driver and download and install the latest version you find, that should do it.. I'm assuming you have the MTP box checked in storage > settings > USB computer connection. Also, reboot both the tablet and the computer after installing the new driver.
Good luck.
I have two different devices one only has web os and the other has android.
on the android I have the MTp checked and have accessed it in the past but i upgraded to windows 8
that being said i had the same issue with windows 7 i just thought a fresh install would fix the issue and it has not
I have downloaded what i thought was teh latest drivers.
I have installed novacom
and rebooted my system.
and I get the same error message Windows does not recognize the device.
i get the connected tone on my computer but I don't get any response on the touchpads
did you put the tablet in usb mode?
i did on the android not on touchpad forgot how to honestly

Try using a different USB lead and plugging into different USB sockets on your PC sometimes I find my PC will recognize it with one socket but not another same thing occasionally happens with my USB sticks. Otherwise I would suggest trying a different PC if you still have a problem that would suggest a fault with the USB socket on your touchpad which I have had to have replaced once.
Fingers crossed that isn't your problem.

This will let TP be recognized on the PC
"If you want to transfer files back and forth from the CM9 touchpad you might have difficulty figuring out how exactly to do it.Here's how you pull it off:
First, tap on your app drawer in the top right of the screen (the little checkerboard). Now, select the "settings" icon.
Now tap on storage on the left-hand pane.
Finally, the tricky part - tap on the 3 squares at the VERY top right of your screen. It will bring down a little drop-down menu for USB computer connection. Tap it and put a checkmark in the "Media Device MTP" box.
Now you can plug your touchpad into the computer at will and transfer files back and forth from it. Easy as pie, I'm not sure why this isn't activated by default, but it's a simple fix if you know what to do."
Sorry I copied this from XDA a couple of weeks ago, so I can not take credit for this but it works great
that is already done on my android, and the touch-pad should auto connect. but neither are it says device not recognized

Did you check my second suggestion/try it on another PC to find out whether you have a faulty USB socket on your Touchpad as they can go wrong?
yes i did and i tried 4 usb ports, but that would be rather unusual for it to go bad on two devices right?

im not sure i read that you put TP into usb mode from webos..if not, google the how to.. really simple..
also, install the novacom again.. iirc, it has the drivers too
to me, this screams missing drivers for both devices.
it wouldnt hurt to go to youtube and watch some reverendkjr vids

Novacom shouldn't make a difference, I have just installed windows 8 on my laptop and haven't installed anything yet , just plugged in the Touchpad and it was recognized straight away
Sounds like either windows is messed up or the USB connector of the Touchpad has gone .
same error on TP + his galaxy??
dam the luck..busted ports on both devices at the same time..
right after a fresh format of windows ; what a coinkadink
if on your very longest shot that win needs new drivers, the palm / novacom etc
process installs them and TP will get recognized and picked up..
he said he does not know how to root his TP to put into usb mode..
i know from recent experience that even when android is in mtp mode, my PC would not connect play w/ it until i had new drivers..
same experience w/ my new nexus 7 during the process of rooting it..

Ok lets get a few things right
I do know how to root my device I did it a while ago and honestly haven't done it in a while so I am rusty
but that being said if you cant access the device at all even in usb mode then you cant root.
And yes now my galaxy s3 wont recognize either.
every time i try it tells me that there was a device error and windows doesn't recognize the device.
i formatted the cpu again and put windows 7 and no help
I have tried two diffrent touchpads one android and one web os
and my phone
to get things right you have to start at the beginning. Windows will not recognize TP w/o the drivers first. It's obvious you have been avoiding that step. you need to go back and do the whole nova com thing to install them before you attach TP to it.. look at the you tube videos. you will be finished in a few minutes. .
