Install FTDI driver

	FTDI chip and OS X 10.10
	Hi All,
	Yesterday I got a FTDI (UART to USB) board from unknown manufacturer. I plugged in to the iMac and without a surprise, it was not working. I have tried all the possible combinations, but no luck. Then after some digging in Apple documentation and Google about kext, FTDI and related, I finally made it. Here are the steps:

	1. In order to disable the AppleUSBFTDI.kext extension (From Mac OS X 10.8 there is Apple driver implementation for the FTDI chip).

	cd /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns
	sudo mv AppleUSBFTDI.kext AppleUSBFTDI.disabled

	2. Downloading and installing FTDI VCP Driver. I used the Mac OS X, 64 bit version.
