the screwdriver works, but windows does not detect a dfu device.
when I bridge the green arrow pins, my arduino resets.I think the chip is just dead. And now? Do I have to program my arduino with a usb-serial programmer?
Replacing the chip is a possibility, to bad that I don't have a reworking station. =(I think I'm going to buy a programmer. Do you recommend the original programmer from atmel, or just a cheap usb to serial programmer from ebay?
Have exactly the same problem. Are you using 1.0.1 ? . I was and when I rebuilt the sketch for 0022 the problem went away !. I have no problems uploading to the other boards I have with 1.0.1 only the Mega 2560. Could it possibly be the software ?.Dougie L
