Data sent back by the motor are corrupted. It can be due to:

Interferences on the bus line:
- Change the 3-write cable, their degrade progressively (especially if it's old)
- 1 tip is to cut the central wire of (only) the first cable to connected to the USB, especially if it's a long cable)
Faulty motor (Flash this motor with a fresh firmware and/or try another motor to identify the problem)
Faulty USB device (such as USB2AX) (try another USB device to identify the problem)
