Hi, thanks for asnwer,
i looked inside gadget.h and found declaration usb_ep_queue
---
usb_ep_queue(struct usb_ep *ep, struct usb_request *req, gfp_tgfp_flags)
---
but i dint find any call for it in zero.c
however, i found it called inside gmidi.c that is close to my project.
as i realized, each time HCD sends request to my device, gmidi_setup
routine is called. But this routine related only to ep0 control
requests.
After creation of device, i made myendpoints enabled with
err = usb_ep_enable(dev->in_ep, &bulk_in_desc);
err = usb_ep_enable(dev->out_ep, &bulk_out_desc);
ep = dev->out_ep;
req = alloc_ep_req(ep, buflen);
then i calling the
err = usb_ep_queue(ep, req, GFP_ATOMIC);
am i right ?
in what handler do i need to call from in/out endpoints to
receive/send BULK data?
in example midi gadget there is only these functions:
static struct usb_gadget_driver gmidi_driver = {
.unbind = gmidi_unbind,
.setup = gmidi_setup,
.disconnect = gmidi_disconnect,
.suspend = gmidi_suspend,
.resume = gmidi_resume,
};
