I very recently purchased a new Arduino UNO starter kit.
I am having problems with getting the installation correct and communicating with the board, although I believe I have installed everything correctly according to the instructions but perhaps someone can point out where I have gone wrong:
So I plugged in the board and Windows tried to install a driver and failed (as the instructions say).
In device manager I pointed the "Unknown Device" to the correct driver in the Drivers file in arduino1.0.1.
The Driver installed successfully and the device was then listed under Ports (COM & LPT) with the name "Arduino UNO R3 (COM3)" (I verified that it was indeed COM3 in the properties.
I then opened the Arduino IDE and checked the settings for the device:
Tools - Board - Arduino UNO,
Tools - Serial Port - COM3 (selected with a tick by it)
I then opened the blink example and tried to upload the code. Sure enough it compiles but it returns the following error:
avrdude: stk500_getsync(): not in sync: resp=0x00
If I hold shift during the upload I get the following message:
avrdude: usbdev_open(): did not find any USB device "usb"
When trying to upload the Rx LED blinks 3 times but the Tx LED does not blink.
I have looked at the error online but so far none of the solutions I have seen have solved the problem for me. Here is some further information on what I have tried:
Loop-Back Test : nothing was returned from this using the serial monitor.
Disabled firewall.
Tried different USB ports.
Uninstalled and reinstalled drivers.
Help would be much appreciated as I would really like to start programming soon.
In Arduino 1.0 and later, you can get verbose output by checking a box in the preferences dialog (holding "shift" uploads via an external programmer, which is why it gives you a different error). Can you post the output from that?
Do you have any bluetooth scanning / communication programs running (maybe in the background) or software for a cellular internet dongle or anything else that might be grabbing USB ports?
