USB2.0

To reduce consumption, USB interfaces are disabled in CM4 by default. If you need to use USB ports, please add the following line to config.txt file.

dtoverlay=dwc2,dr_mode=host

Then reboot the CM4. If you use the newest Bullseye image, the USB2.0 is set to OTG mode by default, and it 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 config.txt file and add the line:

dtoverlay=dwc2,dr_mode=host
