Tried installing the driver and windows shows up an error
If you go to Device Manager and plug in the Uno, what shows up? USB Serial Device or Unknown Device or Arduino Uno with exclamation mark?If you have USB Serial Device, I got that for Windows XP with the duemilanove, you should install the above driver, this is not the case since it does not have the FTDI chip.If you have unknown device, that is what happened with Mega on Windows 7, I had to install the USB to serial COM driver, and the it showed the Arduino Mega with exclamation mark and installed the Mega using the .inf file.Hope this helps.Good Luck
