>Description:
	This patch adds support to the uftdi driver for Intrepid Control
	Systems' vehicle bus interfaces.  These interfaces use the
	FTDI chipset with different Vendor and Product IDs.

	I also addd two additional baud rate enumerations.  The vehicle
	bus interfaces use a baud rate of 2000000.  I also added 3000000
	since it is the other FTDI baud divisor special case.

	A better fix would be to calculate the divisors on the fly
	for any arbitrary baud rate (+ the two 2M and 3M special cases).
