[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?

I'm sure usb door is completely opened

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 just did the new AT&T update and mine is now having this problem. I have to manually go into manage applications > usb settings > mass storage to get it to work now

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 will not recognize touchpad

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

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. .

One solution for Android device not showing in Windows Explorer

This is a quick tip for people with Windows XP who do not see their USB connected Android device in Explorer.
I had the correct cable, MTP mode enabled, the latest USB drivers and the computer was recognizing my phone as
an MTP device but it wasn't showing in Windows Explorer.
It turns out the problem is that the MTP protocol came after Windows XP so it needs to be installed.
The only way to do that is to install the Windows Media Player 10 or newer.

Was USB debugging enabled? I disabled it and it shower up right away.

This particular problem was there with and without USB Debugging.
I also had trouble installing the driver with USB Debbuging turned on.
My problem is that I had manually disabled Windows Media Player years a go because I hate it that much.
I posted this to give people in my situation the heads-up because it took me forever to figure it out.

Nexus 6 not showing up over USB on WIn 8.1

When I plug it in it doesn't auto find the drivers, so I downloaded "UniversalAdbDriverSetup.msi" and that didn't help. I plugged my old GS3 in with the same cable, and windows found it and started installing the driver and it worked. So how can I get windows to recognise my devices. Also when I plug in the nexus windows makes the new usb devices connected sound.

Have you tried downloading the tool kit from here http://forum.xda-developers.com/nexus-6/development/toolkit-wugs-nexus-root-toolkit-v1-9-8-t2947452?
Posted from a Nexus 6 running Slim Rom

For me on Windows 8.1 this is what i did
Go to settings
Go to Storage
Click on the 3 dots on the top right corner
Click on USB computer connection
Then clikc on Camera (PTP)
Then you are done
This worked for me earlier today when my computer wasn't recognizing my phone

This worked for me, I was pulling my hair out for a hour trying to figure it out last night.

Got it working, I just uninstalled the drivers and switched back and forth from PTP and MTP and its now working on MTP.

turn off USB Debugging and then turn on MTP and it should be fine,
worse case, uninstall the drivers completely and then try again.
It should also install different drivers when it is in USB Debugging, for that you have to turn off MTP while USB is on

Connecting to a pc

I'm on the latest update (8.1.0 may security) and I'm trying to connect my 7 plus to my PC, but nothing happens. The PC doesn't install any drivers and my phone isn't showing up in devices. I'm not getting the notification I'm supposed to get on my phone either, the phone is charging though. I have tried to connect to different PC:s as well.
Does anyone else have this problem?

@Floyd
Have you enabled developer mode and set USB debugging to on? Otherwise drivers or not the PC will not communicate with the Nokia.

When the phone is plugged into PC make sure
that on the status bar it is not showing charging on USB but MTP (file transfer) other than that it must be driver related.

You won't get notifications on PC if USB is set for charging only.

Exactly same problem here, my Nokia 7 Plus only says charching and I don't get a notifiaction. My PC also doesn't react.
Have you found any solution yet?

Unplug the cable. Enable developer options, then find "default USB configuration" and change it to mtp. Replug the cable

since it doesn't even recognize that the device was connected to the pc, it was a guess. you can also try to plug it into a different USB port. for me, it did recognize the connection itself but it did not install the MTP driver properly. i just manually installed it from here: c:\Windows\INF\wpdmtp.inf (right click and install)

Going to settings -> System -> about phone, and then find the 'Build number' option, several click it until system ask for password to enable developer mode. After done this, return to settings -> System, find the 'Developer options' and click it, and enable the 'USB debugging' option. Now using the command 'adb devices' will show our phones.

Well I had same issue with Nokia 6.1 plus running 8.1.0 but I was using 3rd party cable which din't support data transfer except charging phone. So I used OEM Foxconn original charging cable and it quickly detect my phone and installed driver itself. try changing cable and turn on USB Debugging if needed.

Is this how you solved it bro, doesn't seem to be working for my phone?

Try a different cable. I had the same issue now and the problem was the cable I was using wasn't fit for data transfer. When I tried a cable which came with the phone it worked.
With the old cable I tried all the suggestions and nothing worked. I would connect the phone to my PC and it would only charge but no option to choose USB mode (file transfer).
Tried another cable and the USB mode option came up straight away. Hope it helps someone
