You can keep the "confirmed" state of this bug, I have a Toshiba Portege r830 laptop with : 05:00.0 USB Controller: NEC Corporation uPD720200 USB 3.0 Host Controller (rev 04) ...and I experience the same problem that I can reproduce everytime.
The steps to do so are : 1) Plug my usb 3 external hard-disk into the usb 3 ports 2) Check the /var/log/kern.log for : usb 3-3: new full speed USB device using xhci_hcd and address 5 usb 3-3: Device not responding to set address. 3) Nothing will ever happen in this state, and the disk isn't recognized by the system. I have found a workaround to be able to use the usb3 disk normally at full speed : 1) Plug the usb3 external disk to the usb3 port 2) rmmod xhci_hcd (it may takes 1-2 minutes to remove it) : [99018.528062] xhci_hcd 0000:05:00.0: remove, state 1 [99018.528083] usb usb3: USB disconnect, address 1 [99021.284289] xhci_hcd 0000:05:00.0: Timeout while waiting for a slot [99071.468495] xhci_hcd 0000:05:00.0: Timeout while waiting for a slot [99071.678375] usb 3-3: device not accepting address 4, error -62 [99071.678391] hub 3-0:1.0: cannot disable port 3 (err = -19) [99121.652723] xhci_hcd 0000:05:00.0: Timeout while waiting for a slot [99121.652736] hub 3-0:1.0: couldn't allocate port 3 usb_device [99121.652748] hub 3-0:1.0: cannot disable port 3 (err = -19) [99121.653412] usb 1-1.6: USB disconnect, address 10 [99121.654358] cdc_ncm 1-1.6:1.6: usb0: unregister 'cdc_ncm' usb-0000:00:1a.0-1.6, CDC NCM [99121.739368] xhci_hcd 0000:05:00.0: Host controller not halted, aborting reset.
