Hello all, I'm working on a new USB device controller driver for U-Boot. And I need some advice how to properly implement it. Could you please describe what is gadget.ep0? - Why ep0 defined separetly (not included in end points list)? - Why other end-points has "in" and "out" `struct usb_ep` descriptor, but not ep0? -- Best regards, Oleh Kravchenko
