Hi!
Please, advice, how can i handle the request USB_ENDPOINT_XFER_BULK
inside client's API.
i'm unsing dummy_hcd.ko module at debian 6 kernel 2.6.32.
I correclty handling ad gadget side the control requests, using
usb_gadget_driver
.setup function
it handles control request only with setup packets.
my gadget device uses USB_ENDPOINT_XFER_BULK for ep1 and ep81.
at dummy_hcd.c code i found only
/* non-control requests */
limit = total;
switch (usb_pipetype (urb->pipe)) {
case PIPE_ISOCHRONOUS:
/* FIXME is it urb->interval since the last xfer?
* use urb->iso_frame_desc[i].
* complete whether or not ep has requests queued.
* report random errors, to debug drivers.
*/
limit = max (limit, periodic_bytes (dum, ep));
status = -ENOSYS;
break;
case PIPE_INTERRUPT:
/* FIXME is it urb->interval since the last xfer?
* this almost certainly polls too fast.
*/
limit = max (limit, periodic_bytes (dum, ep));
/* FALLTHROUGH */
// case PIPE_BULK: case PIPE_CONTROL:
default:
treat_control_like_bulk:
ep->last_io = jiffies;
total = transfer(dum, urb, ep, limit, &status);
break;
}
=======================================================================
any device's side way to receive and emulate such requests?
tanx,
