Here is error message from my Lynx Point-LP machine (MacBook Air early 2014).
xhci_do_command() in xhci_enable_slot returns timeout.
xhci0: xhci_open addr 0 depth 1 port 5 speed 2
xhci0: xhci_do_command input 0x0000000000000000 0x00000000 0x00002400
uhub_explore: usbd_new_device failed. error=TIMEOUT
uhub0: device problem, disabling port 5
Other ports has similar errors.
And I cannot use any USB devices.
I have USBVERSBOSE and USB_DEBUG in my kernel config.
