Hi, after spending hours trying to get my Arduino Mega 2560 REV3 connected I still can't figure out what's going wrong.
I have tried different cables and different computers.
Arduino doesn't even show up as "unknown device" in device manager or even make a noise when plugged into windows PC.
Can anyone help or is my board just faulty

I have the same issue as well.
In my case, when i plug the arduino mega, it makes sound but no detection.
As a result, i could not do firmware update.
I kinda found out that my arduino is a clone after making some research.
i have taken another pain to buy genuine arduino mega board from arduino site.

The clones generally use a different serial adapter, usually a CH340G - these work fine unless you need to update the fw on the 16u2 in order to make it behave as a different type of USB device (like UnoJoy to make it behave as a mouse, keyboard, or joystick), and I generally recommend them over the official ones because it is fairly easy to burn out the 16u2.
Regardless of whether it is a clone or official board, if you want it to act like a serial adapter, there is no need to update f/w

SO how do i update the firmware on the clone?
I searched the forum and it looks like im going to need another device, download firmware from github and them connect the "other device into my computer and arduino clone into the "another device"

Which operating system are you using?

If it has the same TTL-to-USB chip (16U2 or 8U2, not sure which one is used), you do it the same way as for an original. If it's not one of those, you can't.
