How can I enable a gadget device on both USB interfaces?
The devicetree already contains the USB as OTG.
Linux sees both USB, both only creates my gadget on USB0.
I do not create a gadget device by using ConfigFS, just good old code in a module.
Do I need to set a certain property in a struct or in the DTS?
I am using Linux kernel 5.4.0
&usb0 {
status = "okay";
dr_mode = "otg";
};
&usb1 {
status = "okay";
dr_mode = "otg";
};
