During multi-gadget.sh the last line of that script fails:

ls /sys/class/udc > $GADGET_PATH/UDC results in: ls: write error: Device or resource busy

in dmesg I see: [ 80.470962] UDC core: pi4: couldn't find an available UDC or it's busy

that eventually leads to:

DEVICE_UVC: Device open failed: No such file or directory (2).

It does work with showmewebcam (which uses an older 5.10.11 kernel) and it fails with raspbian bullseye with kernel 6.1.21+ (6.1.34+ also fails).
