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?

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 have the exact same issue with my Arduino UNO R3.
I have a regular Arduino UNO, which registers the USB port when plugged in - but when using the R3 - it fails to show the USB.
Any idea why the R3 wont show up the USB and y old Arduino UNO will?

Have you installed the Rev3 device driver?

Code: [Select]
Arduino UNO REV3.inf

I'm using mac os 10.6.8 - is the .inf file just for pc?
I have a pc lying around here as well, so I will install the Rev3 driver on that and see what happens.
