when receive eem echo command, it will send a response, but queue this response to the usb request which allocate from gadget device endpoint zero, and transmit the request to IN endpoint of eem interface. on dwc3 gadget, it will trigger following warning in function __dwc3_gadget_ep_queue(), if (WARN(req->dep != dep, "request %pK belongs to '%s'\n", &req->request, req->dep->name)) return -EINVAL; fix it by allocating a usb request from IN endpoint of eem interface, and transmit the usb request to same IN endpoint of eem interface.
