Have you installed the Rev3 device driver?

Code:
Arduino UNO REV3.inf

I can find this file inside the Arduino IDE folder but how can I install it?
On the device manager ( windows 8 ), when I connect the Arduino Board there is no change in the listing so I don't know where to install the driver.

What can I do on the mac? Since it previously worked, the driver must be already installed.

You can have it on a charger and the USB at the same time. Did you maybe reverse the polarity on the charger at some stage?

What else did you connect to the Arduino?

I don't think I have reversed the polarity on the charger.
I was using LEDs, motors, arduino ethernet.. Nothing strange.
I suspect there is a problem with the EEPROM. Maybe by accident I short-circuited with the digital pins with a wire during an experiment.

Hello,

I was normally using my Arduino for small projects and samples.
When I tried to connect again my arduino on the computer yesterday, the Arduino IDE wouldn't recognise the usb connection and I couldn't upload any program on the board.
I tested the board on both Windows and Mac. The same problem occurs.
On the Mac, the only available serial ports when I connect the Arduino are:
  • /dev/tty.Bluetooth-Modem
  • /dev/tty.Bluetooth-PDA-Sync
  • /dev/cu.Bluetooth-Modem
  • /dev/cu.Bluetooth-PDA-Sync
The IDE automatically chose the /dev/tty.Bluetooth-PDA-Sync port since the USB is not available.

On the Windows, the COM1 port is available and selected.

When I try to upload the program on the board I get the following error on Mac:
"avrdude: stk500_recv(): programmer is not responding"
and Windows:
"avrdude: stk500_getsync(): not in sync: resp=0x00"

I used it mostly on a 9V charger and one time by accident I connected the USB at the same time when the charger was also connected.
Why is this happening since I could use the Arduino some days ago? Is there a hardware fault?
