"stereopi starter kit" sounds like the v1.
In v1, you "have to" power the stereopi with the white JST connector. If you power it with the micro USB, it enters in device mode and the USB-A connectors are then disabled.
Maybe it is what happens in your case.

Hi Shigure,
For the StereoPi v2, you can use any method of power, and this does not affect the USB status.
But CM4 requires this row to be added to /boot/config.txt to enable the USB hub:

Code: Select all

dtoverlay=dwc2,dr_mode=host
PLEASE NOTE: this row is already added to config.txt files in our SLP2 and OpenCV images. You need to add it only if you are using the new stock RaspiOS image. Here is our Wiki note for this: How to use stock RaspiOS with the StereoPi v2.
