    Hmm, Greg.

    I seem to get this problem possibly more commonly at boot these days:

    usb 1-6: new full-speed USB device number 2 using xhci_hcd
    usb 1-6: device descriptor read/64, error -71
    xhci_hcd 0000:00:14.0: Setup ERROR: setup context command for slot 1.
    usb 1-6: hub failed to enable device, error -22
    usb 1-6: new full-speed USB device number 3 using xhci_hcd
    usb 1-6: device descriptor read/64, error -71
    usb 1-6: hub failed to enable device, error -22
    usb 1-6: new full-speed USB device number 4 using xhci_hcd
    usb 1-6: Device not responding to setup address.
    usb 1-6: Device not responding to setup address.
    usb 1-6: device not accepting address 4, error -71
    usb 1-6: new full-speed USB device number 5 using xhci_hcd
    usb 1-6: Device not responding to setup address.
    usb 1-6: Device not responding to setup address.
    usb 1-6: device not accepting address 5, error -71
    usb usb1-port6: unable to enumerate USB device

    and my keyboard doesn't work. I then unplug and re-plug it, and get

    usb 1-6: new full-speed USB device number 9 using xhci_hcd
    usb 1-6: New USB device found, idVendor=2516, idProduct=0020
    usb 1-6: New USB device strings: Mfr=1, Product=2, SerialNumber=0
    usb 1-6: Product: Quickfire Rapid i
    usb 1-6: Manufacturer: CM Storm

    Any ideas? Some setup delay that isn't long enough at boot time for a
    slightly finicky device? It has happened before, but now I've gotten
    it twice within a couple of days:

    Nov 02 12:18:56 i7.lan kernel: usb 1-6: device descriptor read/64, error -71
    Nov 28 16:54:06 i7.lan kernel: usb 1-6: device descriptor read/64, error -71
    Nov 30 11:26:35 i7.lan kernel: usb 1-6: device descriptor read/64, error -71

    (I've had this keyboard since mid-September, and looking at the logs
    this machine has been rebooted 41 times since, with those three
    failures..)
