On a resume, when the power is lost during hibernate, the USB core will call hub_reset_resume for the xHCI USB 2.0 roothub, but not for the USB 3.0 roothub: [ 164.748310] usb usb1: root hub lost power or was reset [ 164.748353] usb usb2: root hub lost power or was reset [ 164.748487] usb usb3: root hub lost power or was reset [ 164.748488] xhci_hcd 0000:01:00.0: Stop HCD ... [ 164.870039] hub 4-0:1.0: hub_resume ... [ 164.870054] hub 3-0:1.0: hub_reset_resume This causes issues later, because the USB core assumes the USB 3.0 hub attached to the USB 3.0 roothub is still active. It attempts to queue a control URB for the external hub, which fails because all the device slot contexts were released when the USB 3.0 roothub lost power: [ 164.980044] hub 4-1:1.0: hub_resume [ 164.980047] xhci_hcd 0000:01:00.0: Get port status returned 0x10101 [ 164.980049] xHCI xhci_urb_enqueue called with unaddressed device [ 164.980053] hub 3-0:1.0: port 1: status 0101 change 0001 [ 164.980056] hub 4-1:1.0: hub_port_status failed (err = -22) [ 164.980060] xhci_hcd 0000:01:00.0: `MEM_WRITE_DWORD(3'b000, 32'hffffc90008948440, 32'h202e1, 4'hf); [ 164.980062] xHCI xhci_urb_enqueue called with unaddressed device [ 164.980066] xhci_hcd 0000:01:00.0: clear port connect change, actual port 0 status = 0x2e1 [ 164.980069] hub 4-1:1.0: hub_port_status failed (err = -22) [ 164.980072] xhci_hcd 0000:01:00.0: get port status, actual port 1 status = 0x2a0 [ 164.980074] xHCI xhci_urb_enqueue called with unaddressed device [ 164.980077] xhci_hcd 0000:01:00.0: Get port status returned 0x100 [ 164.980079] hub 4-1:1.0: hub_port_status failed (err = -22) [ 164.980082] xHCI xhci_urb_enqueue called with unaddressed device [ 164.980085] hub 4-1:1.0: hub_port_status failed (err = -22) [ 164.980088] hub 4-1:1.0: port 4: status 0000 change 0000 [ 164.980091] xHCI xhci_urb_enqueue called with unaddressed device [ 164.980094] hub 4-1:1.0: activate --> -22 [ 164.980113] xHCI xhci_urb_enqueue called with unaddressed device [ 164.980117] hub 4-1:1.0: hub_port_status failed (err = -22) [ 164.980119] xHCI xhci_urb_enqueue called with unaddressed device [ 164.980123] hub 4-1:1.0: can't resume port 4, status -22 [ 164.980126] hub 4-1:1.0: port 4 status ffff.ffff after resume, -22 [ 164.980129] usb 4-1.4: can't resume, status -22 [ 164.980131] hub 4-1:1.0: logical disconnect on port 4 This causes issues when a USB 3.0 hard drive is attached to the external USB 3.0 hub when the system is hibernated: [ 6249.849653] sd 8:0:0:0: [sdb] Unhandled error code [ 6249.849659] sd 8:0:0:0: [sdb] Result: hostbyte=DID_ERROR driverbyte=DRIVER_OK [ 6249.849663] sd 8:0:0:0: [sdb] CDB: Read(10): 28 00 00 00 2a 08 00 00 02 00 [ 6249.849671] end_request: I/O error, dev sdb, sector 10760 Make sure to inform the USB core that *both* xHCI roothubs lost power.
