Dear Sarah, I am seeing an issue when trying to transfer data over IN endpoint with TAG (stream_id) value greater than or equal to 16. The device and driver is working fine for the TAG values from 1 to 15 without any issues. I have made sure to allocate 31 streams for the endpoint. When I dig into the xHCI sources, I found that it submitted the data to the host controller with TAG value as 16 (i.e. I saw the stream id as 16 in functions xhci_urb_enqueue(), xhci_queue_bulk_tx(), xhci_triad_to_transfer_ring(), xhci_stream_id_ring() etc) for that URB data. Here my question is, is there any configuration that is required for supporting the stream id >15 for a particular endpoint as we are able to transfer with the same stream id with other endpoints? We verified the HCC PARAMS and it shows the value 4 in bits 15:12 Maximum Primary Stream Array Size (MaxPSASize). The bits 14:10 Max Primary Streams (MaxPStreams) in endpoint context also showing 4. Any inputs / ideas will greatly help us. If you need any further information, please let me know. I will provide. Thanks and Regards, Ramya. -- 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
