FTDI Basic Breakout - 5V

I have the breakout attached to my Netduino by connecting Pin 0 to TX on the breakout, Pin 1 to RX on the breakout and ground to CTS(pull down). I did not connect the GRND and VIN pins on the breakout. I got scared I might damage the Netduino. Don't know why, I just hesitated. Hooked the usb cable to my PC, fired up Putty and it worked. That is with one problem described below. Should I connect VIN and GRND?
When I plug the breakout into Windows, Windows 7 installs USB Serial, COM Port, and Microsoft Serial BallPoint drivers. The BallPoint driver makes my mouse jusp whenever data is sent to the PC. The work around is to disable the BallPoint device in Device manager.
The main thing I want to find out is whether I should attach VIN and GRND. But, why in the world is that dang Mouse driver getting installed?

1. The FTDI driver comes with both VCP and D2XX drivers. It automatically switches between them as needed. In the past, you did have to manually indicate whether you were using VCP, and before that, the drivers were offered separately.
So no need to worry about this issue.
2. connecting Vin and GROUND, -- quickly looking at the ftdi breakout schematic, i do not see a Vin line on the i/o connector. I notice that there are a few different versions of this breakout; 3.3V, 5V , and 3.3V/5.5V Arduino compatible; Since the Netduino is 5V compatible, it will work with 5V or 3.3V. In any case, the ground should be connected to complete the circuit.
3. ballpoint driver, uninstall the ballpoint driver, uninstall the FTDI driver, reboot and reinstall FTDI driver. plug in your module.

The VIN is labeled 5V on the breakout. I don't think it needs to be connected because I'm not going to be [or can't] power the board from the breakout.

on the Vin, yes, you can have bus power or self power. So when powered on the bus, Vin is disconnected because Vin comes from the PC host.
