Oh, if we don't add dtoverlay=dwc2, the usb port is driven by dwc_otg driver by default, if we add dtoverlay=dwc2, then the usb port is driven by dwc2.
And I tested with only dtoverlay=dwc2 (no dr_mode=peripheral), i could see usb0 net device both from rpi4 board and my host machine (via ifconfig -a). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1861070 Title: Raspberry Pi 4B: USB OTG is not working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi2/+bug/1861070/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
