HI
USB-C Input (5–20 V PD) + USB-C Data (USB2.0 D+/D– to STM32H745) + charging phone at same time + Audio data transfer
Problem:
When I connect the USB-C input supply (PD 5–20 V), the phone only charges and the audio USB port does NOT appear.
But when I do NOT provide PD input power, the audio USB port appears correctly.
And if the audio port is already active, then when I connect the PD input afterwards, the phone does NOT charge — only the audio stays active
