Then reboot the CM4. If you use the newest Bullseye image, the USB2.0 is set to OTG mode by default, and occurs the error in CM4:
config failed, hub doesn't have any ports! (err -19)
To remove the errors, you can remove the line otg_mode=1 from the config.txt file and add the line:
dtoverlay=dwc2,dr_mode=host
