Hi
Whenever I try to connect the phone to my computer using USB, it simply gives the 'connected usb device' sound and after that nothing, it says the device cannot be recognized or, on a very rare occasion.. It works (2 times in the past 2 months). I tried numerous things, but nothing seems to work.. I just want it to show up as a Diskdrive, nothing more. I run Windows Vista Ultimate x64.
I just tried connecting to another computer with Windows XP. Without any problems, it recognized and installed it in a few seconds. So there's nothing wrong with the device itself or the cable.
Thanks in advance
So for 3 days now i have been reading thread after thread on xda. i cant seem to connect my phone to my computer. Every time i come across a new link to drivers i try it but still no dice.
What happens:
Install Drivers
Phone set to mass storage
plug usb in
mount sd
windows thinks...
USB Device not recognized
Phone: Captivate, stock everything (with ota update)
OS: Windows 7 64 bit
What am i doing or not doing?
I apologize in advance if i have not stumble across thread where this has already been answered.

Try uninstalling all the drivers and try one again using x64 (I know you probably did it already, but just confirming).
Maybe try doing a factory reset?
So i uninstalled the drivers using the uninstaller application that came with the download then i deleted the files off the computer.
went to the captivate wiki on xda, downloaded the 64 bit drivers from that link (look exactly the same as the other links), then ran the installer application from that download.
what happened was at the end of the install wizard it said that: "mss install wizard was not completed... install wizard was not succesfully installed samsung usb driver for mobile phones.".
I did however notice that at one point in the wizad it called the driver x86 instea of x64.
i would be lieing if i didnt say i hated samsung right now. o yea and i think at&t too. ha ha
Thanks for the help! : )
so in addition to hours spent on other days, im about 5 hours into trying to make the phone connect today.
it seems worse now, it only sometimes sees a device it cant recognize.
i tried more batches of driver uninstall/installs and i even downloaded the full kies.
nothing seems to make it go. im about to lob this thing across the room. any other suggestions or people with a similar problem?
any help would be much appreciated.
1) Scrub your system again of all Samsung drivers.
2) Go to Samsung Software & Firmware Downloads and get the Mini Kies program.
3) Install Mini Kies, this will install drivers.
4) Set USB settings on phone to ask on connection, Settings>Applications>USB Settings>Ask on Connection
5) Connect phone to computer
6) Select Mass Storage when the phone asks
7) Mount phone to computer, depends on which ROM you are running
8) Report back,
I'm running Windows 7 x64 Home Premium and have no troubles connecting. Hope this helps.
ok thanks for the tips.
Here's what i did:
Download mini kies from the link (i noticed that there were driver there to but i did not download that link)
Set phone to ask on connection
plug phone into computer
set to mass storage.
mount sd card
computer says "usb device not recognzed"
Mini Kies still says "please connect mobile phone"
i scream!
what do you suggest i do from here?

Have you tried a rear USB port instead of a front? I don't know why but many have claimed this was the trick. It should not work, but for some reason it does for some.

The usb ports on the back of the computer are usually connected directly to the motherboard. The usb ports located other places on the computer are usually connected to the mother board via a secondary card of some type - this adds another level of hardware and software drivers required to make those ports work. Also it is not unusual for some usb to operate at different power levels - often referred to as powered and non powered ports.
So not all ports are the same which is why some people have different results on different ports on their computer.
One other option that sometimes works: turn on usb debugging in settings/applications/development. Then connect the usb. Pull down the notification window and select the button that says something like "select to copy files...". This brings up a dialogue box asking to mount the phone, and you select that.

I have built many machines and never had a device work on one USB port and not on another.
All my USB devices that require power, require an actual AC adapter -As for unpowered ports - never heard of that. Powered and unpowered hubs yes - but not unpowered ports.

First, just to make this clear all usb ports are powered, and so long as they are in compliance with the usb standard they are powered to 5v.
Second, what you referring to with powered/non powered usb hubs is a usb hub that has a secondary power source (ie includes ac power cable maybe) vs a usb hub that is only powered by the usb serial bus via the usb connecter to the computer.
What was referring to in powered/non powered usb port is a technology included in some ports that allows that port to use the power of two usb ports in one port - not sure but I believe it is an ibm technology - which is some times referred to slangly and inaccurately as powered usb
Now the point of my post was to point out even though there is a universal standard for usb - depending on how these ports are actually connected to the serial bus on the mother board will affect they way they perform - ie usb on the back of the computer that is mounted directly to the mother board serial bus vs one connected via a pci card.
And even though you have never experienced differing performance in your usb ports does not mean that it doesn't happen - it is actually quite common particularly with devices that both connect via usb as well as charge its battery via usb.
I currently have a computer with 7 usb ports all of which will connect and work with my wife's ipod - but I have found two of these ports that will not charge her ipod. most likely this failure to charge her ipod is due to the hardware (or the software driver for the said hardware) in between these two ports and the mother board.
In all of the computers you have built have you built any that had usb ports mounted directly on the mother board serial bus that you also connected a usb pci card to allow for more usb ports? I guarantee you if you do this often enough you wil eventually build a computer that has usb ports with differing performance.
while the info on usb is nice : ) i would very much appreciate any help on gettingmy phone connected. thanks!

I'm guessing by now you have tried all your ports, lol. have you tested your phone on other computers and/or with other usb cables?
One thing to try is check and see if there are any driver updates for the usb hardware in your computer. You can usually find these updates with the computer vendor and/or mother board manufacturer support.
Sorry I missed your post earlier about connecting to a mac - when you connected to the mac was your phone in debugging mode?
I don't know if it is necessary to connect to a mac, but to get some linux distros to mount the drives in cappi it has to be in debugging mode and while linux and NEXTstep are different they are in the same family, have the same ancestor. maybe if someone with a mac read s this they can let us know if it is needed.
If you keep connecting to different computer with no luck, try a different usb cable.
Actually its connecting to a pc. I just tried to connect to a mac wouldn't work there either.
But I've tried all the different combos of debugging and mass storage options it just says it doesn't recognize the usb device.
I have tried a bunch of different drivers and using both kies and mini kies.
Windows 7 64 bit
Laptop
Captivate (stock everything)

getting unrecognized usb device is almost certainly a driver issue - what ever kept it from working with the mac is something else.
have you downloaded and installed the drivers dg has linked in his odin 3 one click thread?
Second have you had a chance to check if your computer had any usb driver updates? One of my machines would not properly identify my phone that I tried reinstalling drivers on and I found there was and update for the mother board usb controller - after updating it instantly recognized it.
I am having the same issue with an added twist, which is that some USB ports will rapidly disconnection/reconnect the device to windows even though I havent unplugged it.
I have/had adb working on both my old laptop, and desktop. And like the OP I have spent many hours trying to get this to work. Very frustrating.
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.
Some reason my desktop wont work usb with android products (mine are note 3 and note 8 tablet). in device manager the samsung MTP Device comes up but with a excemation code 10. in usb controllers theres a samsung mobile usb composite device( is that supposed to be there?) if i uninstall that then reconnect my phone it shows up in explorer for like a minute then dissapears then back to where im at. if i plug it into another pc its works fine so i dont know whats wrong. btw im running windows 10
no help?
Is the computer a trusted device under development settings? Maybe try a different USB port or USB cables?
I've done so much to get this to work. I don't where to look for that in dev settings. I've done different cords/ports. It works on my laptop just fine. It's a driver issue and I don't feel like reinstalling windows lol
Tried all the usual, different USB ports, different USB version ports, different computers (3 of them) and different OS's (Ubuntu on 2 machines and Windows 10 on 3 machines).
One one windows computers I installed the Moto software, no go. On 1 Windows comp I installed the JavaSE and Android Dev software still no help.
I've rebooted the phone, turned dev mode and USB debugging on, then off, then soft reset, then while plugged in, every combo.
Phone will just charge only over USB. Isn't even detected as an unknown device, just nothing but charge mode.
I have a file I'd like to move to the root folder on the Droid to see if I can root it, but I can't move it to root directory via file mangers as the areas protected so I don't know of any other options. I even tried to download it from a SFTP and it still gave it access denied while trying to dl to root.
Droid XT1254, 5.1, Build SU4TL-49
Has no other symptoms of software errors in the phone, works like a charm otherwise.
Wow, I tried a 3rd USB cable and it worked. No idea why the other 2 didn't. That's it folks!

Some USB cables are only "charging" cables, not data+charging.
I found out the hard way one time myself.
