At bind-time you have to have that max_streams flag set. This happens currently only once in the life time of gadget. Meaning: - dummy's init, max_streams != 0 - load gadget, connect at HS, max_streams drops to 0 - replace the gadget while dummy is unconnected - the new gadget gets only eps with max_streams = 0. bind is done only once. Since a gadget grabs endpoints only once it is wise to grab those with max_stream capability _if_ the gadget supports SS. However if you happen to connect at HS speed you may not use your stream feature even if the endpoint supports it. >Alan Stern Sebastian -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
