Dear Experts, We have struck at the Stream ID issue. Could any one tell us about the streams usage in the USB 3.0 with xHCI host controller interface. We allocated the streams through usb_alloc_streams API and filled the stream_id field in the URB structure with required stream id (in this case with 1). However, if my device is trying to send the ERDY using the SID 0x01(Which is being send using Command IU), xHCI is responding with ACK using 0xFFFF SID. Why it (xHC / xHCI) is sending the NoStream for the stream ID (0x01)? Apart from calling the usb_alloc_streams and setting the stream id in the URB strcuture, do we need to do any more? Please respond to this email and help us in resolving the streams issue in USB 3.0 with xHCI code. Thanks in advance.
