Hi,

When booting Liquorix 4.19.0-13.1 on my Thinkpad T460S running Ubuntu 18.10 I get variations of this at the beginning of the boot:

:: Code ::
kernel: usb 1-5: new full-speed USB device number 12 using xhci_hcd
kernel: usb 1-5: Device not responding to setup address.
kernel: usb 1-5: Device not responding to setup address.
kernel: usb 1-5: device not accepting address 12, error -71
kernel: usb 1-5: new full-speed USB device number 13 using xhci_hcd
kernel: usb 1-5: Device not responding to setup address.
kernel: rfkill: input handler disabled
kernel: usb 1-5: Device not responding to setup address.
kernel: usb 1-5: device not accepting address 13, error -71
kernel: usb usb1-port5: unable to enumerate USB device


Everything seems to work and my desktop seems smoother when using Liquorix. Any idea what this is and whether I should worry about it? I do not get that output with stock kernels.

That just means you have a USB device that's not responding. Hopefully you don't need it, or maybe later in your logs the device resets and connects properly.
