The host side always uses tag 0 if streams are not used. If you reply with this tag id, the host side fails to find scsi command and aborts. After looking at the uasp v1 spec I find this: | When the command is complete, the device responds to the IN (Stat) with | a DATA (Stat, SIU). The SIU contains | the tag of the CIU. This would mean that the host side is doing it wrong. I could change that part and see how it goes. But, what do we do if the folks in Redmond get it wrong? >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
