| |
| [ 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 |

| [ 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. |
