It does not turn on servos of robot and not recognized by Windows

uArm Serial No.: 508cb17679A6
Firmware Version: 3.2.0

Operation System: Win 7, 8 y 10

uArm Controlling Method: uArm Studio 1.1.15-a1

We have problems with the robot, we connect the charger turning on the LED, but it does not emit sound and it is not detected as a device, nevertheless when it is connected and it turns on only with the USB, it is detected and we can Firmware reload.

Have you tried turning the robot on first (with powersupply) and then connecting the USB connection.
Best regards

Hello Feko:

Thanks for your answer, but we try this sequence and another, without good result

Is the power supply LED stable if you turn on the arm?
can you use the arm without the computer (programming by moving)?
