I have a Samsung Galaxy Ace II that for a unknown reason, each time that I plug my smartphone via USB cable to my PC, most of the times, my device is not recognized.
When is not recognized, I have to follow this steps:
- Open device manager
- Select portatil devices.
- Select the driver that has the warning sign > Update driver
And between 20 segs - 1 minute later, I receive this message (in Spanish):
My PC is a Windows 7 Professional - 32 bits.
I bought My Samsung Galaxy Ace II more than a year ago and it wasn't rooted or any similar changes to its system.
After check the Register as says in this source, I can't find the upperFilter entry. I really don't know what else can be done.
I already installed Samsung Kies as suggested in his comment #1, but my device isn't compatible with Kies.
Windows Update sometimes finds and installs Device MTP USB missing driver, but when is not found, I can't plug my device in my PC.
What could be the cause of this behavior?
