I'm running windows 7 x64, and Cyanogen's 3.9.7 and suddenly my computer stopped recognizing my phone, it didn't replace the driver with something else, when I plug my phone in it doesn't even communicate with the computer. There is no drop down to mount, and the computer doesn't even see it as being a connected device, I've tried USBDeview and it doesn't show up as being connected at all. I have no idea what to do. Help would be great.
Does it appear in Device Manager?

Nope, not at all.
Tried it with more then one usb cable? One of my cables went bad not too long ago... Also could try different usb port. If all else fails.. try it on the different computer just to rule out hardware issues. If it does not register on different PC then you may need to exchange you device...
Good luck
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
So I'm having an issue connecting my captivate to my Windows 7 64bit machine. (Seems to be a common problem) I've installed the drivers from the posts on these forums. I have changed the USB settings to Mass storage also. If I plug my phone in, Windows will "sometimes" recognize it and the internal and external SD will show up in "My Computer" This only happens sometimes and moving the plug to other USB ports gets it to recognize. I'm then able to mount and everything works fine. But the problem I'm having is USB debugging mode. Any time I have this turned on and plug my phone in, Windows will "attempt" to install a driver but after awhile fail. I've tried to manually install the drivers but no luck. Anyone know why just USB debugging will not work? I tried it on my friends computer who has the exact same version of Windows and the exact same drivers for the phone and it works find every time I plug it in, USB debugging or not. So strange.
Thanks
Try a different USB port on your PC.

I don't think anyone knows where the problem lies. Seems more likely it is the PC or a windows 7 x64 issue.
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

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?

In webos when you plug in the USB it will come up with a prompt. Remember to safely eject before disconnecting.

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?

i also just tried it on my galaxy s3 using a usb port and it gave me the same unknown device error
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. .
