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.

I have tried to with both stock Ubuntu kenrel and the latest Liquorix kernel and the output of lsusb is the same for both:

:: Code ::
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 008: ID 138a:0090 Validity Sensors, Inc.
Bus 001 Device 007: ID 04f2:b52c Chicony Electronics Co., Ltd
Bus 001 Device 006: ID 8087:0a2b Intel Corp.
Bus 001 Device 061: ID 1fd2:6007 
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub


Only the Liquorix kernel posts the USB error messages during boot. What could the reason be for that? Again, everything USB I use on my laptop works.

bus 1 device 5 does not seem to be in your lsusb output.

So it may be only that liquorix is reporting the error, and the stock kernel is not, but in both cases, the error is there.

Try: inxi --usb -xxx to see what is actually there as far as the system is concerned.

Note that this feature is only in inxi 3 and greater.
