Dear experts,
I have 1 question about how to process multiple streams in UASP(USB attached SCSI Protocol) and maybe you can help me to clarify it. Thanks in advance...

As we know UASP is based on USB 3.0 Bulk Stream and built on top of it. We can imagine multiple streams with different Stream ID share the same pipe(communication pathway) and streams are transferred via host/device multiplexing...

My question is:Assume there are 2 streams(ID = 1 and 2) then the processing sequence might be: (we can assume these 2 streams are successfully processed without any error !)

Scenario 1:
- stream 1 is selected and then process stream 1 "until all data is processed"...
- then stream 2 is selected and process stream 2 "until all data is processed"...

Scenario 2: stream 1/2 will be divided into multiple sub-streams and the processing sequence is:
- process part of stream 1
- process part of stream 2
- process part of stream 1
- process part of stream 2
- (... multiplexing until all these 2 streams are completed... )

which one is correct ? or there is another scenario ?

* That is, the selected stream is always processed until it is completed then another stream can be selected, it is correct ?
