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.

alright i tried
every single usb port (it a laptop btw sorry should of said that earlier)
and also with and without debugging

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.
Hi everyone,
I'm using a Galaxy Tab 10.1n and experiencing some problems with the device since I recently rooted and flashed it with the latest Overcome rom.
The tab has some multifunction-adapter on its bottom where you can plug in the data cabel (ending with an usb plug) or some USB/SD-card adapter to directly connect an USB-stick or a SD-card with the tablet. When I connected the tab with my computer using the data cabel the device was recognized by Windows and a autostart dialog was shown offering the possibility to browse the tab. And when I plugged in an USB stick using the adapter it was recognized by the android system on the tab.
I'm writing "was recognized" since this is no longer the case since the time I rooted the tab. Right after the rooting was finished - so before I flashed the Overcome rom - when I replugged the tab to the PC an error message appeared stating that "an usb device was not recognized", in the details it said "One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it." A click on the balloon took me to the device manager showing an "unrecognized device" which status was "Windows has stopped this device because it has reported problems. (Code 43)".
Since then the behaviour kind of changed when connecting the tab to the computer. Now there is no popup what so ever coming up on the computer, on the tab side there is the usb connection sound and a message box stating "USB connected" with "MTP connected" in smaller letters right below.
Well, and this kind of freaks me out. On the one hand the tab says there is an usb connection available but the computer won't recognize the device (already reinstalled Kies and the usb drivers alone). On the other hand the tab won't recognize any device attached to it via the adapter.
So I tried to flash a stock rom to the device... failing in trying to do so since Odin won't get an usb connection to flash the files from the computer to the tab.
Sooo: Anyone out there who can give me a clue what is going wrong and how I can fix it?
You are in wrong forum. This is for galaxy tab 7" original.

Oh, sorry. Searched for Galaxy Tab and didn't thought about another board for the specific versions...
Could a mod please move this topic to the right board?
Hi Xda, I have a problem with my hd7. I got a new phone so I gave it to a family member. After a week or so I got complaints that it wouldn't connect to the computer so I checked it out... The hd7 won't connect to any computer, I've tried every possible usb port as well as several different versions of Zune and nothing helped. When I plug it into a computer is says that the usb device is not recognized and in device manager it lists the hd7 as an "unknown device". Also in the device description it says that no drivers were loaded for the device. Is there anything I can do to fix it???
You clearly hate the Search bar or are really Lazy

Hi guys, so I have a little bit of an issue! I've had my nexus 6 for about 3 months and i'm not sure when it happened or why but some how and some way no matter what rom I'm running, USB connection to desktop no longer works. I have tried turning adb on and off, reloaded drivers, and tried other computers. When I monitor device manager in Windows 10 no new devices are connected at all, just does not show up. No unknown device, adb, USB, nothing. So I'm not sure what I should do, I was thinking of claiming warranty however trying to avoid it. Any suggestions??????
P.S: Mounting external storage devices using otg is successful.
May there be some problem with your cable. Try different cable on all available usb port.
I've done that, no success
Was going to transfer some Roms between my phone and computer when I suddenly start receiving this notice:
"The last USB device you connected to this computer has malfunctioned and windows doesn't recognize it"
Upon further inspection in the device manager I get this:
Unknown USB Device (Device Descriptor Request Failed)
I've tried uninstalling it numerous times and have tried reinstalling the official Samsung drivers but nothing is working. It's not working on any computer I try it with so at this point I don't know what else to do. It was working fine just a few hours ago.

check your usb cable it may have become damaged causing no communication between your device and the computer.
Forgot to mention that my phone is able to charge but cannot be recognized by my PC for whatever reason.
Have tried multiple cables, USB ports, and tried on a different PC. None of which will let me go into the explorer but they are charging my phone.
Turn on a bright light and have a close look at the connector inside the phone, it may have dirt/lint/debris, or even corrosion from water exposure. You might take an old tooth brush to it

Thanks for the suggestion. I tried it and nothing changed. It still charges when I plug it up but the computer still says it's malfunctioning.
