Hi,
I am trying to use the usb otg port of our custom board as usb_ether interface. Everything works fine without device model enabled. But since everything new should be done with DM I tried to use usb_ether with CONFIG_DM_ETH and CONFIG_DM_USB.
The usb_ether driver searches for an UCLASS_USB_DEV_GENERIC, but the only way to get such a device is to init usb. whenever I init the usb OTG port gets detected as hub. I looked at the u-boot usb stack code and did not think its possible to use usb gadget driver with DM enabled at this time.
Can somebody who is more familiar with the u-boot usb stack confirm this? Or is it just my fault?
Devicetree entry: &usbotg { disable-over-current; dr_mode = "peripheral"; status = "okay"; };
Defconfig: CONFIG_DM_ETH=y CONFIG_USB=y CONFIG_DM_USB=y CONFIG_USB_EHCI_HCD=y CONFIG_USB_EHCI=y CONFIG_USB_STORAGE=y CONFIG_USB_GADGET=y CONFIG_CI_UDC=y CONFIG_USB_GADGET_DUALSPEED=y
