it means that complete() function at gagdet side handles one endpoint. In my code i made one complete() function for both 01 and 81 endpoint.
The complete callback is assigned to a request not an endpoint. Actually making a single complete function which handless all requests on all endpoints is most of the time suboptimal. It's usually much better to have separate complete functions for endpoints (or even for different requests but let's not complicate things just now).
Dont understand, how to send readed data from endpoint 81 to host. in complete function i receiving data correctly, but cant's send any data back from endpoint 81.
To send data through an IN endpoint, you need to initialise request correctly and fill the buffer with data.
what correct sequnce to BULK read from endpoint 81 ? HCD sends usb_ep_queue to endpoint 81, then i need to fill req->buffer with correct data and return it back, but how to do this?
No, you need to first fill the buffer and set other fields of the request and then queue.
In loopback code gadget it just redirects queue from OUT to IN endpoint. Do i need to make 2 complete functions for 01 and 81 endpoint?
You don't have to but in the end it's more readable and maintainable as you don't have to have condition in the single complete function. -- Best regards, _ _ .o. | Liege of Serenely Enlightened Majesty of o' \,=./ `o ..o | Computer Science, Michal "mina86" Nazarewicz (o o) ooo +-----<email/xmpp: mnazarewicz@xxxxxxxxxx>-----ooO--(_)--Ooo-- -- 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
