Is anyone else having trouble connecting their Galaxy to a PC? I don't know whether mine is faulty or not. Downloaded the Samsung Kies software but when I plug in the Galaxy Windows is unable to find a MTP USB device driver and the phone refuses to connect. This happens on both XP and Windows 7. Also the Galaxy has a complete fit and keeps flashing between the home screen and MTP application screen while it's connected. And I don't get the usual Android option to mount for file transfer. Am I missing something?

Not sure if it helps but I mentioned in another post of major initial problems connecting either Windows or Mac ...

For Windows, turn off phone, plug usb in to PC, then turn on while plugged in.
For Mac, goto Settings, About phone, USB Settings, Turn ON USB Debugging.

Unfortunately USB Debugging doesn't play well with Doubletwist. Let's hope a more permanent fix comes up.

I have the same problem, could you confirm that you are using Windows 7 64 bits? MTP USB driver issues seems to be current with 64 bits OS...

[savvase]

I have EXACTLY the same problem i am using windows 7 professional 64bit can anyone help solve this annoying problem?

[Airwave11]

It seems that only the mode Kies does not work, if you use Mass Storage mode or Media Player mode, it works perfectly!

[bushrat]

I solved this problem (Win7x64, JF3) Try unmount and remount internal SD then try to connect to KIES. If not then unmount and format internal SD.
I have really no idea how this helps but it solved my issues (My first android phone haha)

Hope this helps :S

Also there is a '64x samsung USB driver' floating around. I'm using that atm but I'm not sure if it really helped as it gave me the same problem untill I formatted the internal SD. I would try first without changing driver. Goodluck.

I've had no issues whatsoever to connect, after installing Kies and the x64 drivers a few posts up, (Kies also updated itself), I connected the phone in mass storage mode, it loaded some drivers and I could access it from Windows. Disconnected, enabled USB debugging mode, reconnected, it installed more drivers. adb works fine. Unmounted and disconnected again, and turned off USB debugging mode. Reconnected and this time chose Kies. Again installed more drivers (MTP drivers), I started Kies, it found the phone, connects with no problems and all functions work fine.
adb, mass storage, debug, kies, you name it, it all works great.
Windows 7 x64, XXJF3 firmware. (just got it today, so happy)

Lose stuff like music, pics vids(if saved to internal).. also some app stuff, eg downloded extra skins for clock widgets, downloaded maps, podcasts etc.

Having the exact same problem, though I can connect it as a mass storage device and mount the drive. When I choose Kies as the connection method the MTP application pops up and then closes over and over again. It worked a couple of hours ago, then installed a few apps and copied some stuff to the SD card and troubles began.

So far I've tried to unmount and mount the internal SD card, reboot the device and my pc (Windows 7 x64) without USB cable attached, rebooted device with USB cable plugged in with USB setting set manually to Kies and tried the option to let me select the connection method and choosing Kies. Seems like the only solution is to format my SD card as bushrat tried ?

Edit: it was indeed the solution. I've copied some important files from the SD card to my pc (media files, gestures for Dolphin HD, themes for Beautiful Widget, my ebooks etc.) and then formatted the SD card. Then I rebooted the phone, connected it with the Kies option and the MTP application didn't flash anymore, the device driver installed just fine. Unplugged the Cable, started Kies, replugged and I was synced to Kies in a couple of seconds. Then copied back all the files I backed up and everything is fine again. Didn't even have to reboot to enable the themes for Beautiful Widget or access to my ebooks. Just locked an unlocked and it's working like a charm once again.

I just hope this won't happen again.

Had same problem with Kies. But after new firmware and the new Kies from http://samsung-firmw...samsungkies.htm it working fine for me so far.

[Kindred Interactive]

Yes i can confirm that formatting the internal SD card also worked for me. I was already on the latest firmware and kites app from samsung. Just backed up via USB mount to HD and then formated, restated and connection was ok again.
Hope this dose not happen again grrrrrr.

Thanks for the advice above

After days of debugging the issue, I finally nailed it. The MTP application flashes when you have too many mp3 files (most probably other media files also but I am not sure). In my case, I have installed a language learning software that downloads thousands of mp3 files on the internal SD card (for words and phrases in different languages). I have deleted all the languages I did not want and I was left with about 800 mp3 files. It was still not working so my next step was to change the extension of those files so they are not recognized as mp3 files. A phone reset later everything was working fine. Just to confirm it, renamed the files back to mp3 extension - not working again, renaming back to different extension and restart - working.

I hope this helps everyone. I will also submit the details to Samsung support and hopefully they will forward it to technical department and do something about it.

Thank you, thank you Tyxerakias!!

I had been unable to install the ADB drivers on Windows XP SP3. I have no interest in Kies at all, but following the above steps for Kies magically enabled ADB support as well. The ADB USB driver must have some dependency that is resolved by the setup of Kies.

Thanks again,

Is this problem no longer relevant? Interestingly enough, after having it work (following the steps above, posted in multiple forums by now!), it quit on me again. Until i formatted and ran debug mode again. Aggravating...

[upp3rd0g]

I finally managed to figure out what is going on... the Windows MTP driver cannot handle the extra sd-card-partitions. Several people report they have to unmount/remove their external sdcard, but I have to unmount my internal sdcard to get it to work (I don't have an external sdcard.). What may be of influence is that I have the "special" version of Galaxy S which has 16GB internal memory, instead of 8GB. After unmounting the internal sdcard Samsung Kies could suddenly connect properly to the phone.

So in my opinion the trick to get it working is: unmount your sdcards, either internal and external.

[Jared S]

Hey all, I was having the same problem with my brand new Galaxy S today. I fixed it by plugging it into a USB port on the back of my computer instead of using one of the front. Give that a try!

I believe it may have something to do with the phone trying to draw too much current through the case's USB ports. The ports that are right on the back of the motherboard should be able to provide more current.

Arggg... i am having this problem too... and nothing works. I've tried resetting drivers, reinstall them, unmount/mount internal sd, startup with usb plugged in...

Can someone pleasehelp?

EDIT: I have made a video from it @ youtube ==> http://www.youtube.c...h?v=R9hdpJPCP-k
