    Corsair Strafe RGB keyboard has trouble to initialize:
    
    [ 1.679455] usb 3-6: new full-speed USB device number 4 using xhci_hcd
    [ 6.871136] usb 3-6: unable to read config index 0 descriptor/all
    [ 6.871138] usb 3-6: can't read configurations, error -110
    [ 6.991019] usb 3-6: new full-speed USB device number 5 using xhci_hcd
    [ 12.246642] usb 3-6: unable to read config index 0 descriptor/all
    [ 12.246644] usb 3-6: can't read configurations, error -110
    [ 12.366555] usb 3-6: new full-speed USB device number 6 using xhci_hcd
    [ 17.622145] usb 3-6: unable to read config index 0 descriptor/all
    [ 17.622147] usb 3-6: can't read configurations, error -110
    [ 17.742093] usb 3-6: new full-speed USB device number 7 using xhci_hcd
    [ 22.997715] usb 3-6: unable to read config index 0 descriptor/all
    [ 22.997716] usb 3-6: can't read configurations, error -110
    
    Although it may work after several times unpluging/pluging:
    
    [ 68.195240] usb 3-6: new full-speed USB device number 11 using xhci_hcd
    [ 68.337459] usb 3-6: New USB device found, idVendor=1b1c, idProduct=1b20
    [ 68.337463] usb 3-6: New USB device strings: Mfr=1, Product=2, SerialNumber=3
    [ 68.337466] usb 3-6: Product: Corsair STRAFE RGB Gaming Keyboard
    [ 68.337468] usb 3-6: Manufacturer: Corsair
    [ 68.337470] usb 3-6: SerialNumber: 0F013021AEB8046755A93ED3F5001941
    
    Tried three quirks: USB_QUIRK_DELAY_INIT, USB_QUIRK_NO_LPM and
    USB_QUIRK_DEVICE_QUALIFIER, user confirmed that USB_QUIRK_DELAY_INIT alone
    can workaround this issue. Hence add the quirk for Corsair Strafe RGB.
