While reading chapter 5.6(Doorbell Registers) in xHCI spec revision 1.0, it says : When the Command Doorbell is written, the DB Stream ID field shall be cleared to "0". However from the function xhci_ring_cmd_db(...), not find it handle this, is it necessary? Or whether a quirk HC will cause some exception without clearing the ID? --newbie question -- 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
