This is an old revision of the document!
No driver needed, just plug the USB2AX in a USB port and the Status LED should light up very briefly in red then in solid green.
The USB2AX should appear as /dev/ttyACM*.
The user must be part of the dialout group to have access to the serial port!
If the Status LED stays red and the device does not appear in /dev, check that USB Modem (CDC ACM) support is enabled in the kernel. All recent desktop distributions have it enabled by default.
If you plan on using Robotis' Dynamixel SDk for Linux, have a look here!
Same as for Linux, except the USB2AX will appear as /dev/tty.usbmodem*.
Before the first use, you will need to install the USB2AX.inf driver file (Right click > Save as… to download it).
The installation is similar to the one for the Arduino Uno (step-by-step under XP).
Once installation is complete, the Status LED should turn solid green.
This part explains how to connect the USB2AX and make a Dynamixel servo move using RoboPlus Dynamixel Manager, on Windows.
Install the driver of the USB2AX, and the latest version of RoboPlus.
