Hello @Anjali​ and welcome to the ST Community.

If I understand well you are using the STEVAL-SPIN3201 board.

In this board the STSPIN32F0 RESET signal (NRST) is connected to the ST-LINK reset (T_NRST) through the jumper J8.

Try to open J8 jumper and check if STSPIN32F0 operation is independent by USB connection.

The STM32 Motor Control SDK does not manage the potentiometer natively, it is necessary to implement that part of the code independently.
