Arduino Mega 2560 - timeout problem - FIXED

For those of you Mac users who also have trouble uploading your programs to the Mega 2560 because of timeout problems... maybe I have a fix for you!

Download the Wiring app ( and copy the two files ../ and ../ into ../ after renaming the avrdude utility inside there into avrdude_old or something like that.

Now start the Arduino app again. Everything should work perfect now!

Enjoy... ;)

is it going to work on a win7 64bit system? I have the timeout problem as well, it has been driving me crazy

I fixed mine.

i downloaded the usb fix for cheap chinese coppies and then selected the correct port under tool in the sketch prog.

I am soooo happy.
