 This framework can be used with any combination of RS-232 ports, USB to TTL adapters, USB to RS-485 adapters, half or full duplex... but you'll need the right link for the right device.
 
 First make sure that you can access your serial port:
-* If you are running Windows you will need to install the [FTDI driver for the USB2Dynamixel device](http://www.robotis.com/xe/download_en/646927). You may also need other drivers depending on your adapter (like the [CP210x](http://www.silabs.com/products/mcu/pages/usbtouartbridgevcpdrivers.aspx), the [USB2AX driver](https://raw.githubusercontent.com/Xevel/usb2ax/master/firmware/lufa_usb2ax/USB2AX.inf), or maybe the official [FTDI driver](http://www.ftdichip.com/FTDrivers.htm)).
-* If you are running Linux, your will need to add your user account in the `dialout` and/or `uucp` groups in order to access serial port:
->  # useradd -G dialout,uucp $USER

 Latency over the serial port will limit the number of instructions you can send each second even more than bandwidth limitations.
 To minimize traffic on your serial port:
