Hi folks,
I am just getting started with Dynamixel actuators. I bought a USB2AX and two AX-12A actuators and built a "Y" cable using the Trossen Robotics 12-volt adapter. I tested the "Y" cable extensively for polarity and proper voltage. I then connected the servos and as expected, the red light comes on for about 1 second then turns off.
Problem: I tried the ROBOTIS software under Windows, and the Python/Tk dynamixel_hr utility. In all cases, no servos were found.
I then disconnected everything from my USB2AX and scoped the data line as I scanned for servos. The result was per the following photos -- some weird blips of about 0.1V, but nothing that looked like a real signal.

Do I have a dead USB2AX? How could it have died? What could be the issue?
Kind regards,
Ihab Awad
