Hi everyone,
i'm having difficulties to connect my sgs2 to a pc.
i have tried it on 3 different machines (win7 64, win7 64, winxp 32) with the same problem:
I works fine when i first connect the phone in download mode. But as soon as i disconnect the cable i can't connect it again. Windows sais that it doesn't recognize the device and that's it. The device manager shows an "Unknown Device" under USB-Controller. And i am not even able to install drivers by manually pointing windows to a file.
as already sais, i have tried that on 3 different machines. I have tried installing driver via kies and via the driver file that is available here in the forums. i have also tried different usb ports.
Any ideas?
Goddchen
EDIT: Maybe this is an important information: the phone connects fine as long as it is running (can be found via adb, logcat is working, etc...) it only makes problem when in download mode...
I had exactly the same issue yesterday on my Windows 7 box. In the end I connected the phone in normal (not download) mode. Into device manager and uninstalled the drivers through there.
Then I uninstalled Kies and reconnected the phone, I allowed Windows to search windows update to find drivers (not that it did as it couldn't find any and reverted to the local ones. Then disconnect the phone, re-install Kies, run the install drivers from the tools menu, close Kies. Run up Odin and the connect the phone in Download mode, low and behold 2 minutes later after a lengthy installation process the phone was picked up.
I tried a number of things but for some reason this specific order seemed to sort it.
Hey,
thanks for you hints. But they didn't work for me.
I found the problem: believe it or not, it was THE CABLE. I went and got another cable and this one is working fine all the time. The other one doesn't... Very strange...

So I switched to the energy miui yesterday and it worked for like 20 minutes then wouldn't boot up anymore. for hours I kept getting "usb device not recognized" error then out of nowhere I got it to work and started to use odin to flash back. Well during that time it failed and wouldn't start up for awhile but now I can get it into download mode again but my pc won't recognize my vibrant no matter what I do.
I run win 7 x64 with 2 different cables, 2 vibrants (the other vibrant has zero problems connecting and works every time with my pc) and I've tried different usb ports. I've taken the battery out re plugged the usb several times and even tried installing all my usb hubs and nothing.
What can I do to get my computer to recognize my vibrant so I can fix it?
Usually i get "usb device not recognized" message when some stupid reason samsung drivers stop working. What i do is uninstall them, reboot and then install them again. Give it a try, also make sure you're connected to usb port on back of the computer. You can also try heimdall if odin doesn't recognize your phone. Couple of time that has worked for me also.
Try installing Samsung Kies mini, it will automatically install the drivers so that your device can hopefully be recognized, if that does not work, well just use your other vibrant.
I gave that a try but I cannot seem to get heimdall to even work. I keep getting random errors each time. 3 different ones so far. Is there any other way I can do to force my computer to recognize it? And I have the keis but it hasn't helped either. It just tells me to connect.i don't think it is the drivers when my other vibrant connects just fine without problems
If you were in MIUI, you are a going to need the Nexus S drivers for Odin to recognize your phone. You can get them here:

Q: Where can I get the Nexus S drivers?
A: Download and install the Android SDK here then download "Google USB Driver package, revision 4"
Once downloaded, right click on "Computer", "Manage", "Device Manager", "Nexus S", "Update Driver Software", and point it to wherever you isntalled the SDK.

I'm having an issue where my thunderbolt does not recognize my device any longer. I used to have it set up with pdanet and everything worked well for about a week. All of a sudden, any computer i tried to plug the device into, wouldn't detect the phone. A friend of mine has tried his thunderbolt on my computer and it detects it.
When plugging my phone in, it pops up an error message with "USB Device not Recognized." In the device manager, the phone shows up as Unknown Device. I have tried this on 3 different pc's, using 3 different data cables. No USB symbol displays on the taskbar of the phone when I plug it in, however, it does charge.
What I have tried:
Changing data cables.
Using another PC.
Uninstalling device drivers and letting windows re-detect and install.
Downloaded HTC Sync and ran it after uninstalling drivers again and re-plugging the phone.
Changed different Connection settings on the phone, such as USB Debuggin on/off, and changing it to HTC Sync Mode, Charge Only, Disk Drive, etc
Mounted and unmounted SD Card in the phone settings.
OS: Windows 7 x64
Thank you for any help you may provide.
same problem
I have the same problem with HTC mytouch 3g 32B Android 2.2.1 when I plug it through usb under Vista.
Any suggestions?
Try installing the usb drivers from htc if you haven't.
http://dl4.htc.com/RomCode/Source_and_Binaries/USB_driver_20101122_release.zip
I have download the HTC usb drivers but when i go to control panel and uninstall the unknown device it just reinstalls it. when i try to update drivers using the location
ie C:\Users\sxristi\Downloads\android-usb-driver\Android USB Driver\i386
i get a reply
The best software for you device is already installed. Windows has determined that the driver software for your device is up to date.
and it continues to point to
unknown device
Oh one more things i got the usb drivers from Android SDK Manager the google usb drivers revision 4 and the weird thing is that i do not get the trident usb nor the debug icon on my HTC when i plug it in to my vista. I did get it once or twice before but not in general since the usb devices are not recognized. However when i boot on my Ubuntu os then i do get them recognized. so i guess the problem is with windows drivers somehow...
Thanks for the replies.
I've tried to install the drivers from HTC but Windows says that the driver is not compatible with my the device.
Also, I tried on a system with Windows XP and everything worked as intended, but I cannot get it to work properly in Win 7 x64 anymore.
When my win7 comp no longer sees my Tbolt I have to toggle the USB Debugging off then back on. Usually within a few seconds it reads it again. If that does not work I have also used the option to turn on internet pass through then change it back to hard drive mode. Either of those usually work for me. My drivers I used were from android sdk if that makes any difference. Hope this helps.

HTC
My problem continues under Vista OS. I called HTC and they told me to re install their Sync after removing Adobe Air and all HTC drivers and Google USB drivers. I did that and reinstalled Sync and still nothing. They also told me to call microsoft for it seems operating system conflict.
My conclusion yields toward windows conflict. But I can not figure out this conflict. Perhaps something I have installed does not let my vista recognize the HTC android device and uses the windows usb drivers to create this "Unknown Device" under usb serial bus controllers. once it is an unknown device forget about Sync or ADB etc... The phone is just not recognized as android and you can not do much with it via windows.
For the person who suggested to turn "USB Debugging" on-off, i did that and still the computer recognizes that there is a usb device but again it says "usb device not recognized unknown device.."
any additional suggestions???
I've verified that my phone works fine on Windows XP. I still cannot connect to windows 7, though.
Try turning OFF Fast Boot and turning ON USB debugging. this helped for me.
same problem
I have a similar problem too .. i know its not the computer as other phones and pen drives are working ok.
Plus this phone has same problem on other computers too, where as other phones work fine.
So it has to do something with the phone and not the drivers or computer in anyway
I have the same problem, no PC recognizes my HTC Thunderbolt. Now change cable and tried with windows xp, 7 and 8. Is there any solution I can not root. I want to change the rom factory rom I do not like but I can not do anything because I do not recognize the usb. Also the menu does not appear when I connect via USB in the notification bar.

When simply powered on, Odin will recognize my tab (10.1 WiFi Only 7510). But will not recognize in DL mode... grrrrr. Any suggestions?
Have you tried to uninstall and reinstall the drivers on the PC?
Yes, I did. Reinstalling the drivers did not work. I tested with USB debug off, this did nothing in Odin either.

Of course it wouldn't; toggling a USB debug setting on the device while booted into it's operating system will have no affect on how the device is going to work in download mode as download mode is completely independent from the operating system itself. It's like comparing a PC's BIOS to an installation of Windows or Linux on the PC.
Your issues with Odin and download mode are most likely on the PC side and NOT on the tablet side. The Samsung drivers are very temperamental. Sometimes they don't play well with other devices and sometimes they don't work well with certain chipsets or USB controllers. My suggestion is try different USB ports, avoid using USB HUBs and try reinstalling drivers as well as disabling antivirus on the PC temporarily.
It may even be advantageous to have device manager open while you connect the tab in download mode to see how the PC is recognizing it. The tab should never be connected while you're attempting to get into download mode, leave it disconnected and have Odin fired up and prepped until you get the tab in download mode. Seeing how device manager picks it up might help diagnose driver issues.
same problem, varios computers
Hello everyone! I also have this issue whereas my gt-p7500 dont even exists to the system in download mode. I tryed 3 computers so far, even on linux in download mode heimdall wont recognize the tablet. what I have done so far:
(on 1st pc win7)
- installed kies, and updated to latest version. On normal mode the tablet gets recognized, all drivers install throught the end, kies works fine, managing folders and files as storage device also works fine.
- turned on usb debugging, and connected to pc again. A new driver MPC is installed, kies still works, pc communication also.
- rebooted the device in download mode, and after this conected again to the pc. Nothing new is detected.
-- Odin can see the device on normal mode, and if its turned off (charge mode) but on download mode nothing happens.
(on 2nd pc, win 7)
- didnt install kies, only samsung drivers
- inserted the tablet in 3 ways on the cpter, normal node, normal mode with debugging on, and download mode to all new devices and drivers to be detected.
- odin dont work on download mode, but can see the tablet as the example above, normal mode, normal mode with debug on and turned off (charge mode)
(3rd pc, debian 64)
- installed heimdall via git, latest package. Also wont detect the device on download mode, whereas it can see the tablet on normal mode.
on 3 pcs, tryed ALL usb ports, tryied openning odin first, and then connecting the device, tryed conecting the device first and then openning odin... nothing works while in download mode.
also Iv reseted the device to factory defaults to test, nothing changed.
On the first pc iv also tryed downloading older drivers versions from samsung, spreaded all over xda foruns on other threads. the oldest version Iv tryed was 1.4.x,
Please helpe me on this, cant figure out how to get the device detected in download mode on the pc... getting very annoyed on this already, and tryed all the possibilities I could imagine so far.
Are you using a laptop? Bcz pc can iddntify. I also had same problem with my laptop. It was recognizinging it as media device but not in download mode. So try to cknnect it to the CPU of the Pc
HIT THANKS WHENEVER POSSIBLE OR IF I HELPED YOU...
Not necessarily computer related, past experience for me has shown that not all versions of Odin work with this tab......the newer versions are NOT so good
Try this version uploaded and these drivers - try odin first if you are sure of your drivers, otherwise install the drivers first
Let us know how you go....

Samsung Galaxy TAB P1000(Ordin detection in DOWNLOAD MODE)
Initially google SAMSUNG_USB_Driver_for_Mobile_Phones_x86 . Download the file in your pc or laptop and install it. Then switch-off the tab and Press power and Volume down button simultaneously to get into the download mode. This time Samsung tab would be detected in the Ordin.

try installing Kies?
Its ok i got it to work. Went into download mode and plugged into my PC and windows installed some drivers, Odin detected the phone just fine. Then i booted up into android like normal but switched to PTP mode, windows then installed the MTP drivers (though it was already installed) then after that all worked well again
Please help...
Im having the same problem. But nothing seems to work for me. Tried everything possible. Re-installed drivers, connected in download mode, installed Kies, reset to factory setting..ALL TO NO AVAIL. I keep getting 'USB device attached to this computer has malfunctioned...' message...
The solution isnt always the same for all users.. Fortunately mine was fixed by a simple driver install. I remember browsing the internet and found out that there is a way to fix it but it requires simple adb commands and the Android SDK.
Hello everybody,
I have a problem with my Samsung i5500. Every time i try to connect it to a PC it is not detected as a mass memory device and gos straight into charging mode just like i would connect the phone to the socket charger. The PC does not recognize the phone, it doesn't do anything, just like i never connected the phone through the USB port, but the phone is charging.
I tried to connect the phone on 3 different computers using 3 different micro-usb cables. On all 3 computers I installed the latest drivers for the i5500 and the same problem occurs every time.
Can anyone please help me with an advice. What should I do in order to get my phone connected and recognized by the PC?
In case you it helps you to know, I am using the stock 2.2 ROM and the phone is not rooted.
Thank you in advance.
i have EXACTLY the same problem, and it is not drivers problem. Any advice?
hey guys, This is the link to download for drivers.
http://d-h.st/iPk
If you use windows 8 or 8.1 then you will have to extract the file you download from the link above and then right click on the .exe file and go to 'properties', in that go to 'compatibility' and in that choose your operating system as "WINDOWS 7" and check the option below 'always run as administrator' and there you go. Double click on .exe file and follow steps. Install drivers. No need to restart the pc also. (if your phone also do not detect after installing these drivers only then restart).
Can you just try this out? I know it is maybe not driver problem but still you can try this.
