My Trinity device is not recognized by any of my 3 pc's using any of USB ports. The problem started when I wanted to try a different ROM. I currently have 20070418_RUU_Trinity_LVSW_WWE_1.25.0.8 installed. I wanted to install img-32424-mUn_1_25_AKU3_5 but during the reboot after the ROM transfer the connection failed for the USB connection, after which I gave up and thought well let's try again and soft resetted the device. However I was never able to get a Active Sync session going again. The OS is still booting fine so I feel I am trying to fix something which is not entirely broken. I also tried the suggestion for flashing from SD card, but that did not load the TRINIMG.nbh file as I hoped (and read) it would. So I have a IR connection and possibly a bluetooth connection (I left my bluetooth module at work so I cant test this) Will this be my free ticket out of jail? Thanks for your input.
I seem to remember something about someone loosing USB connectivity after installing and messing with the GPS icon. This probably won't help but I would try in your case.
Start>Settings>Connections>GPS
Program Port>None
Hardware Port>None
Baud>9600
Check manage GPS automatically
Exit & turn phone off
Turn phone back on
Doesn't work?
You are no worse off
Works?
Reset hardware port to Com 9
Uncheck manage automatically
Leave program port to off
Set GPS software to com 9 9600
tried it, but didnt work.
Does the USB connection work in bootloader mode by any chance? (Hold the power and camera buttons down and reset with the stylus).
Try to delete the ActiveSync partnership on both the PDA and computer and then reestablish it ... it may have nothing to do with USB at all.
Problem went away after I forgot to turn off the PDA while it was connected to the wireless. It apparently didnt switch itself of because it was dead when I tried to turn it on. After charging it for a while I could turn it on, and as by a miracle the USB interface finally connected properly with my laptop. It didnt give the error "Windows has encountered an unknown device on your USB port" So thanks for all your input sofar.
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

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 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.

For some reason, out of nowhere, my computer or phone are deciding not to connect to each other, which it was working fine last night and hundreds of times before that on the same laptop, suddenly when i plug my phone in now it says drives failed to install, and so i downloaded that latest LG Android Device Drivers, and still wont work. Any thoughts on how to fix this ?
Do you get the USB connection icon on your phone? If so, this shouldn't be that hard to fix. It's probably just a driver issue. I would uninstall the LG and Android drivers and start over. Now, if you don't get the USB icon on your phone at all, then you either have a bad USB cable or SD card. I had this problem for months before I figured out it was my USB cable that was the problem.
If driver issue with Windows, uninstall drivers, reboot, install drivers, reboot, after Windows loads then plug in the phone, then try everything starting with Charge Only, then Mass Storage, then Internet Connection Mode, and all the drivers should install fine
If this fails you can try ADB over Wifi in the Play Store. It bypasses a lot of issues if you are just trying to use adb on your phone. If you need files off your phone try Wifi File Transfer. No wires or cables needed. Both just need an existing Wifi network to transfer/push/pull files.
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...
