1) On connect I see the following messages. xhci_hcd 0000:00:11.0: ERROR Transfer event for disabled endpoint or incorrect stream ring This was eliminated using the following scissor patch. ---------------------------------8<------------------------------------ [PATCH] usb: storage: unusual_uas: Add JMicron JMS56x to unusual device This device gives the following error on detection. xhci_hcd 0000:00:11.0: ERROR Transfer event for disabled endpoint or incorrect stream ring The same error is not seen when it is added to unusual_device list with US_FL_NO_REPORT_OPCODES passed.
