I forgot to mention that we also tried the boards.txt fix - changing the protocol to wiring and this did not help. We even restarted the Arduino IDE several time with the wiring protocol line but still no action.

xvjeko - this is very interesting and we are all waiting for David Mellis to throw some light on this. What you have described sounds like one of two things - bad soldering or incorrect fuses in either the 2560 or the USB chip. Since all the boards were tested at the factory, something must have happened since. Bad soldering can cause this -talking about intermittent open circuits caused by a poor solder mix or not enough paste. Remember that solder paste must always be kept in a fridge when not being used. The other option of having fuses not set correctly can also cause intermittent operation - such as the brown out enable not turned on. A third scenario is faulty Atmel chips which is a small possibility -luckily Atmel is very open about Erratas do these can be easily checked.

Anyway, sounds like a lot of Arduino users have the same problem, so a workaround would be nice.

Problem with Mega2560 is huge. There are very many people with the same problem. Is there any official opinion yet?
I'd really like to use my Mega2560 normally.

Awesome, im so glad i got rid of my uno for a mega!

Way to go Arduino, now i cant do anything.

Same issue here. same on mac/ubuntu/and win 7

I was warned not to get a mega and now i see why

OK, picked up the Mega2560 from my friend last night, and tested it out on the Lenovo Win7 32bit desktop and HP Win7 64bit laptop, and it works fine on both. The only variation from the Uno is the driver takes a long time to load (2-3 minutes - OK maybe not that long in the big scheme) and opening the serial monitor takes a while to reset the Mega - maybe 5 seconds. The Mega works well on our LED and LCD shield and takes only slightly longer to load.

So the issue looks like a Dell issue. Maybe if anyone has a dead Mega2560, please report the make, model, operating system, and any other details which are show when you right click on My Computer and select Properties.
