Problem to connect Samsung to computer

[guest]

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, go to Settings, About phone, USB Settings, Turn ON USB Debugging.

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...

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.

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

System: Windows 7 Ultimate 64 bit
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.
