USB unknown device

I've tried the drivers from Samsung, Keis, ODIN one click. None of them worked on 4 different machines, Windows 7 both x64 and x86(which was a fresh install), and two Windows XP machines. I tried it on Ubuntu(10.04 LTS) and that recognized the captivate.
Anyone know how to get one of those to correctly recognize my Captivate so I don't stuck on Samsung's/AT&T's 2.2

uninstall all of the driver that you downloaded. uninstall kies. then go to samsung.com search for the captivate, choose you phone, click the 'i own this' button. then go to get downloads, software. click on the .zip file icon next to usb drivers. if that didnt work uninstall them then download kies again. if it still doesn't install them, open kies, click menu, reinstall drivers

What is it that you're trying to do?

If it is coming up unknown device try another port. You may want to try another microusb cable as well.

I've always had luck with the drivers in the captivate aio toolbox. Even on a fresh win7 64bit when I replaced my boot drive with a ssd a month ago.

Samsung really failed at the USB drivers for the Captivate. I would expect to be able to install the drivers from their website. Plug in my phone, and have it working.

I'm trying to:
1) connect as a mass storage devices. Yes I know turn on USB debugging and to mount the drive.
2) flash back to stock 2.1 or root my phone so I can install a custom ROM on it. Might go with CM7/MiUi or something from Team Phoenix. So use Odin3

Tried all of the ports on the computers. I don't have another microusb cable to test to see if that's the problem, but I'll check that tomorrow.

I'm going to try a fresh install of windows 7 32-bit with aio toolbox see if that works.
Tried my friends brand new microUSB cable. It worked.

I have tried 4 known good cables know, 4 different computers and every USB port available on all 4 of the PCs I tried. Only once did it identify the device and install the drivers and I was able to root it but I still can't sideload because after the reboot after rooting it is back to device not recognized/unknown device. This has been a total pain. Any suggestions? I'm not with AT&T any more so I am out of luck for just bringing it into a store and asking them to take care of it.
Edit: Sorry for bumping an older post but I did it instead of starting a new thread.

If you're just trying to transfer apk files to it for sideloading, you can use a wifi transfer app. I use Wifi File Explorer and it's great. You can connect to your phone via web browser and upload/download anything on the SD card.
Another option is to use an external SD card that you can remove and plug into your computer, transfer the files to it, then insert it back into the phone.
This won't work for connecting to PC apps like Odin, Heimdall, or Kies, but for simple file transfers it works like a charm.
Additionally, regarding other usb cables, you didn't mention what types of cables you used, so I'll throw in another thought. The cables that come with the Captivate don't work on some PCs (like my new iMac). Third-party, generic usb cables might not work, either (I tried some and got a whole lot of fail). The only cable that works for me is the one that came with my wife's Motorola phone. If you haven't tried one yet, I would recommend getting your hands on a Motorola cable and testing it out. You'll immediately notice the cable is much thicker. I don't know if that has anything to do with why it works when others don't, but there's something about that cable that others don't have.

Bad Phone?
Could it be the phone port is having issues?
I've had the same problem and it seems that the port on the Captivate is shot which may be your issue. it will always charge; but tends to cause a lot of profanity when trying to get a PC connection to transfer files or flash it. It will be seen, then immediately play the 'unplugged' sound from windows. I've sat there and had it play the tones of plugged in and un plugged over and over again just by tilting the phone from side to side. No matter what cables I use (tried several but they are all samsung due to the recessed port). If it establishes the connection; I have to be very still with it or it'll lose it. If it loses it; I get unknown device messages or not functioning messages on that port until I reboot the PC.
Trying to flash anything via ODIN takes a lot of patience.
Those same cables / USB ports are used on my wife's Focus without ever having a problem. I wrote it off as too much flashing / overclocking of my phone but am not sure.

hi i was having this issue as well. i solved it by:
1. download a good & stable miui rom, rename it to update.zip and place it into your sd card. i took the sd card out of the phone and used a adapter to connect the sd card to my PC since i can't access my sd card through the usb port.
2. put the sd card back into my phone, turn off my phone. press and hold volume up and down buttons, then press n hold the power button till the screen shows something.
3. select install from sd. wait until the installation finishes and select reboot the phone.
4. when you're in your new miui rom, try to connect your phone to the pc via usb port again.
this worked like charm for me.
about the miui rom, i suggest you to use the one from miuiandroid.com (the UK version)
after flashing the rom im able to connect via usb and use mass storage.
hope this helps

Also, when you uninstall drivers, don't forget to look in the program files for anything that may have been left behind and delete it.

From the description it sounds strongly like you are actually experiencing a port failure which is common on the Galaxy S devices. PM me if you need this repaired...

Only try another usb cable, i bricked my cappy with a bad contact cable on odin, unknown device too, new cable=i897 device on windows notifications
try and feedback!

strange, this only happened to my when i soft bricked my phone. try connecting it to your computer in download mode

I had this issue once before. Here is what I did which resolved the problem. I was using a windows 7 PC
1. Download the ADB kit and extract it to C drive.
2. Connect your mobile to the PC on USB port
3. Wait for the drivers to be installed automatically (it might give you a failed to install message)
4. Never mind that message. Open Device Manager
5. In Device Manager, if you expand the "Universal Serial Bus Controllers", you'll see a device that has yellow question mark against it. This is your phone and since drivers are not installed properly, it has the question mark.
6. Right click that device, and select "Update Driver".
7. IN the window that comes up, select "I'll select a driver".
8. Browse to the folder where you have extracted the ADB kit on C drive
9. Check include subfolders and click Next.
10. The drivers should be be installed and your device should be identified by the computer.
Let me know if it works for you.

[Q] Why can I no longer mount usb

I have erased the contents of the phones internal USB storage. Now I notice that I cant mount to my PC.
Anybody know what happening or had same problem

Have you already tried formatting with CWM?
Perhaps this thread contains some useful information for you.

Typed it in and got nothing. Using the android dialler when I pressed the last * the dialer cleared and did nothing.
Just installed the SDK so I could use (hopefully) ADB. When trying to install the Google driver rev4 windows says that rev 4 is no better than the one currently installed.
Also when I connect to the PC it says that the USB device is not recognised either.
I reckon my next thing to try flashing a new Rom via ROM manager.

well that didnt work in fact it has got considerably worse. I used ROM manager to download and install a new rom but didnt install the Gapps how daft do I feel now cos all I got is version of Blandroid running with no Android Market access to download ROM Manager.
I can access my WiFi network so I thought I would simply visit XDA via the mobile browser and download a fresh version of CM7 and then re-flash via ClockworkMod . However all I get is download fail error. I guess it doesn't know where to save the file.
So to recapp I have the following
a Nexus S (running Blandroid ROM)
a Win XP laptop that does not recognise my Nexus S (therefore cant install the Google driver to use ADB)
The Nexus S recovery is ClockworkMod and accessible.
I cannot accept that it is bricked (not just yet anyway)
I have another Laptop with Ubuntu installed. Will this help me in anyway to find a fix. I am not that experienced in Linux unfortunately.

1
i have the same problem. only thing you can try is.
pull out battery. let something metal touch the usb conecter .conecting the metal to a unload source(for static electricity.)
wait couple of hours,and try again.
if that didnt work.
2
open your nexus.
unplug all cables and screws from the main board.
again touch the usb conecter with something metal that has a ground source.
and try again.
the last step worked for me the 1st time pluging it in after i did that.
after that. usb didnt work again.
it probably has to do something with the usb phone charger and static electricity.
but i havent tested it.

will give that a try when I have a bit more time.
In the meantime I have been setting up ADB on my other laptop running Ubuntu 11.04. But unfortunately the Nexus S didnt register on the OS either. I thought you didnt need additional drivers for Linux only windows! I am really puzzled now as I thought the Linux option would have allowed me to flash a different ROM other than Blandroid (which isnt bad its just I dont have the Gapps installed)

you still have wifi/3G and CWM or bloothoot?
download the Gapps zip. put it on dropbox or any hosting site.download it trough your mobile browser and flash it trug CWM.
or use blutethoot to download it.
might be a short fix.until you get USB to work.
(this is how i do it cuz my usb doesnt work.)

I did try that but for some reason after stating that the download had started - Download Unsuccessful was displayed in the notification area. As useual I open a door only to find a brick wall on the other side.
In the meantime I am back with my HTC Hero.
Thanks for helping anyway!

seeing you have HTC here.why not tranver your zip trug your hero to your Ns?(with bluethoot)

boy, i hope you haven't started tearing your phone apart yet...
since you still have access to cwm: try to format your sdcard with it. looks like you haven't done that yet.

I would try to uninstall all drivers and associated programs on your PC. Then reinstall the drivers. Windows can be very finicky as you know. Also try PDANET drivers.

Same PC with dual boot? Yeah, try another cord and a another PC. The fact that you plugged it in and it's recognized in some way in the tray says something is fubar. I just don't know if it is the phone though. Best of luck.

Nah, different laptop and different cable. Hope that it charges OK. Gonna have to get a WiFi file transfer app working to move files to and from.

glad to help out :3
there are allot of people that have this USB isue and its HW NS related. nothing we actually can do about it.plus it also happens after changing kernels and roms(i supose) overclocking might be 1 of the reasons thus the voltages not being original.
btw,sorry for my half assed english x3

Having the same issue. I tried that, no such luck.
My computer *did* connect at one point though... couldn't mount USB storage (wasn't prompted) but it did ask for a driver, and currently has a Samsug USB one installed. It won't accept the SDK driver (not 64-bit capable? Or NS4G? Idk...)

[Q] USB connection related problems

hello,i have several problems that are making me very angry.i use updated windows 7 32 bit.
1.i have samsung kies and my device was working normaly,but then today when i connected my phone to pc i got code 43 error device not recognized.i tryed reinstalling kies uninstalling drivers re installing nothing helps i cant even connect when i am in download mode same error.I NEED SOME ANSWERS ASAP COZ IT IS DRIVING ME CRAZY.
2.this one is bit smaller but also annoying,it was happening while usb connection was still working,when i connect my phone(any mode kies or mass storage),then when i copy files from pc to phone it working fine,but when i try to copy something from phone to pc i get random disconnects (connection loss) there is no logical explenation coz its totally random,lets say i copy 100 pics i get dc after 10 then i reconnect phone and click retry he copy 15 more and dc again.
Any1 will any solution plz help coz my phone is at mess atm and cant flash anything.

the source of the usb issue may be your computer.
1) did you always use the same usb port for your phone?
2) how old is your computer?
3) do you live in a humid environment?
I live on guam, and on my older laptop (only two years old!!!), running winxp, 3 of 4 usb ports are no longer usable due to corrosion. they give errors and even when working, sometimes I could lose the connection by moving the cable slightly. also, the last usb port is now getting difficult to use because it's hard to plug in anything
so, if you answered yes to #1, try another port and be prepared to install the drivers again.
if you answered yes to #3, be prepared to replace your usb if they are indeed corroded

well thnx for answer,but my pc is new like 7 months old,usb ports are working just switched mouse and phone mouse working phone not.its driver relater before i had that error and some1 from xda told me to delete everything(kies drivers) related to phone and his drivers and it worked i also see that error(code 43 is common) but fix with uninstalling driver(worked before now doesnt).thing is that something at that moment didnt work well on phone(last time it was my external sd card had to format it)and now pc keeps repeating same error.simply even tho all drivers are installed i get device not recognized,and under device manager it unknown device,also when i tick option to see hidden devices i see omap 3630 but state is unconnected.

When transferring files to and from pc, do you use the original USB cable that came with the phone? Because when i use other cables, i have this issue, when i use the original cable, no probs at all.
if that also doesnt work, try formatting internal and external SD cards

i use original cable and also i did format both external and internal cards several times my first problem is kinda more important atm.

ok i tried connecting my phone to secondary pc running xp gave me same error but simple uninstall of driver and reinstall made it work cant fix it on win 7.
Edit: damn phone wont connect when in download mode cant flash anything -.-.

Connect the phone and go to device manager
If you see the i9003 driver uninstall it then connect the phone to pc again
now windows 7 will download the driver automatically
that's how I fixed my problem

Can't copy large files to phone

Hey guys
I been unable to copy large files to my phone or the sd card while i use the mtp or camera method. I can copy small files without a problem, but when the file is 100mb or larger i will always get an error. Is there any fix for this?
I attached a picture of the error i get.

I just copied a 350MB file and played it back w/o any problems via USB.
How are you copying the file (USB/WiFi/?) and what platform/tools are being used?

I'm using windows 7 x64 server pack 1. I'm using the original usb it came it but no luck. Tried my nexus usb and still same problem. I always get that error. I can cope other files under 100mb without a problem.
Edit: I try to copy it by my computer were the device appears, do I need a software to copy files?

Welcome to the wonders of mtp!
Are you copying to the sd card? If so it could be a bad card. If it happens on internal storage also ..well you now know why mtp suxs ass.
You might want to try the usb storage mod although that only works for the sd card.
And no you should not need any special software mtp is supported in win7

Damn MTP crap..lol.. I kept trying with no luck, but i notice that the drivers always try to install when i plug and unplug the device. I have installed the drivers before, but the phone kept trying to install with fails. Is there a way to clean my pc of all samsung drivers so that i could try a fresh install again?

I was having the same issue. was pissing me off so badly. my problem was I was using the front USB on my computer. ( I built my own) So I switched it to a port in the back of the computer and it works no problems now. Was weird.....

I'm having the same problem on a mac laptop. I haven't tried a different computer but on the same mac, i didn't have problems with MTP on Galaxy Nexus.
It took some cursing and persistence to transfer my songs over...

GS3 is a crap I sell it for Xperia S. I wish I bought the Xperia S first. GS3 is too expensive and found out that Xperia S has better screen, camera.. And regarding the Quad Core of GS3, It doesn't do much compare to Xperia S, dual core is enough, Quad Core is their advertisement to sell their phones. Multitasking in Xperia S is enough. Opening 10 apps at the same time to make the Quad Core fully functional?? WTF 10 apps at the same time?!?

Carefully check

This error indicates that the GSIII is refusing to have crap music put on it.

I got it to work connecting it on a usb port on the back of my pc and by re-installing the drivers a few times. The copying speed is very slow compared to my old phone. Thanks for the help guys.

[Q] Samsung Infuse USB not recognized by computer

I have a Samsung Infuse and I have rooted it with CM9. Before that I had MIUI latest version with ICS.
But now, my Infuse is not recognized by my computer. When I connect my Infuse to my computer, nothing opens up asking what needs to be done and I do not see my Infuse in my computer (which is running Windows 7).
I believe the problem started when I installed MIUI with ICS on my phone and since then I couldn't connect my phone to the computer.
I installed all possible drivers (Samsung USB drivers, Samsung Kies, Samsung Kies Mini) with no success. I installed the drivers - uninstalled the drivers - reinstalled the drivers - rebooted my computer and tried any combination with no success.
I did my research but couldn't find anything.
I found an article http://forum.xda-developers.com/showthread.php?t=1520061 , but wasn't sure whether it will work for my Infuse.
Also, I looked in all possible locations in my phone but I couldn't find the settings where I can set the action to be performed when the phone is connected to a computer. I think that setting is missing from my ROM.
Please let me know what should I try to make it work.
Thank you

if for some reason you are not able to get the phone's current os to work with your pc, you may need to reflash your rom or bring it back to stock in download mode.

the connection of the phone with your pc in download mode is the most basic connection.
it will be up to you to figure out if it is due to:
1. your usb DATA cord
2. your phone's usb port
3. your pc's usb port
you need to isolate these components to come up with a reason why you are not able to get your pc to recognize your phone.

Have you tried a ubuntu live cd?
When ever I've had problems with Windows (ANY Flavor) my Live Cd has always worked.
You can download Ubuntu here: http://www.ubuntu.com/download
Download and burn to dvd then boot computer
once it loads download qkster's Heimdall One-Click
I can't remember but you may have to get wine for ubuntu (Wine=runs windows programs in linux)
If you need it: Open a terminal (command prompt) and type or copy paste
sudo apt-get install wine1.4
Hope this helps you out.
Keep us posted
