Your thinking is right but your udc driver is wrong. > if it is right,then how can i let set configuration finish before the > host sends USB_BULK_GET_MAX_LUN_REQUEST command? When your udc driver calls fsg_setup, it should NAK the status stage of the control transfer until the gadget driver calls usb_ep_queue(). That will happen after set_configuration is finished. The host will wait until you stop sending NAK before it proceeds with Get-Max-LUN. Alan Stern ------------------------------------------------------- Using Tomcat but need to do more?
