I found this -
In addition to all the features of the previous board, the Mega 2560
now uses an ATmega8U2 instead of the FTDI chip. This allows for faster
transfer rates, no drivers needed for Linux or Mac (inf file for
Windows is needed), and the ability to have the board show up as a
keyboard, mouse, joystick, etc.
have you checked the driver to see it the correct inf file for Windows
is used?
I think the UNO uses the same chip - well probably all of the boards
do
I found this at

Installing drivers for the Arduino Uno with Windows7, Vista, or XP:
Plug in your board and wait for Windows to begin it's driver
installation process. After a few moments, the process will fail,
despite its best efforts
Click on the Start Menu, and open up the Control Panel.
While in the Control Panel, navigate to System and Security. Next,
click on System. Once the System window is up, open the Device
Manager.
Look under Ports (COM & LPT). You should see an open port named
"Arduino UNO (COMxx)"
Right click on the "Arduino UNO (COmxx)" port and choose the "Update
Driver Software" option.
Next, choose the "Browse my computer for Driver software" option.
Finally, navigate to and select the Uno's driver file, named
"ArduinoUNO.inf", located in the "Drivers" folder of the Arduino
Software download (not the "FTDI USB Drivers" sub-directory).
Windows will finish up the driver installation from there.
