I am starting our first Mega2560 board. Windows 7 tries to load drivers from Microsoft update but does not find anything, it wont find those from C:\Program Files\arduino-1.0.1\drivers either. What is wrong?
This particular piece of crap has Windows 7 starter edition in it, could that cause problems?

The drivers are in C:\Program Files\arduino-1.0.1\drivers.
Stop looking for the 16U2 !
Just select the Arduino MEGA 2560 REV3.inf or Arduino MEGA 2560.inf
This is the driver you need..
From the .inf:
DESCRIPTION="Arduino Mega 2560 R3"
SERVICE="USB RS-232 Emulation Driver"
I believe you. But Windows 7 starter and Vista do any find any suitable drivers there. I'll try with an machine XP at home, it usually works. By the way, device manage says it is a Mega16U2. Should there be some Arduino specific bootloader in that USB cpu chip too?

I have Windows 7 Ultimate SP1 X64.
In my device manager it says under ports: Atmega 2560 (com7)
You could try and delete the device and start over again, but I doubt it would work.
Have a look at this : http://arduino.cc/forum/index.php/topic,118440.0.html It's an enhanced installing system which also install all the drivers you might need (want).
Works really well.
Arduino-COMBINED-dfu-usbserial-atmega16u2-Mega2560-Rev3.hex is in C:\Program Files\arduino-1.0.1\hardware\arduino\firmwares.
In the readme there's some info on how to burn this onto a 16u2.
