Perhaps two different types of USB controllers? You can see the mapping between USB buses and PCI controllers with ls -l /sys/bus/usb/devices/usb* udisks2 collects SMART data and this is known to cause problems with some combinations of USB controllers and disk enclosures in UAS mode. It usually recovers after the reset, so not sure why [ 131.357007] sd 0:0:0:0: Device offlined - not ready after error recovery The network issue is possibly unrelated, because in this case the hub simply reports complete disconnection of the device and it comes back a moment later for unclear reasons. I wonder if any of that is preceded by low level USB errors? Maybe try again with some dynamic debug: echo 'func handle_tx_event +p' >/proc/dynamic_debug/control echo 'func handle_transferless_tx_event +p' >/proc/dynamic_debug/control I presume this is not a regression and there are no kernel versions where it works correctly? -- You may reply to this email to add a comment.
