After installing the IDE Arduino 1.0.6, I've connected the board with a USB cable to my computer.
As expected, my computer was trying to install the driver.
And... It found a driver. The board was recognized as a HID Keyboard.
I didn't get a unrecognized device or a extra COM port.
Neither I can replace the driver with the one I've downloaded with the IDE. (Got a message that the driver is not suitable for this device).
Does anyone knows what I'm doing wrong?
How can I get my board recognized as a COM port so I can program it with the IDE?
I've got the same problem on a Windows 8.1 computer and Windows 7 computer.
I've tried that. But I get a message that the best driver is already installed.
If I lookup the VID/PID on the internet, it's for a Atmel LUFA Keyboard.
And I can't find this VID/PID in the INF file of the driver which i've downloaded with the IDE.
Does anybody know how I can resolve this?
Or do I have to return this Arduino to the store?
Thanks for all the replies. I found a solution. Proto-pic pointed me to the VID/PID.
The one I have was not the standard for Arduino Uno.
So I guessed there is something wrong with the Firmware.
I've downloaded dfu-programmer-win-0.7.0. And uploaded the firmware from the IDE.

After I rebootded the Arduino, it was recognized directly.
