libinput not recognizing devices

Hi all. New gentoo user here. I'm having trouble getting my keyboard+mouse working.

`libinput list-devices` doesn't list several devices. Unplugging+replugging usb devices sometimes works, but that's not a solution (it's a laptop). If I unplug+replug a working keyboard, it stops working until I reboot.

My init system is OpenRC. I'm running sway(wayland) as a window manager and don't have X installed. All keyboards work fine in the tty.

Here's the dmesg

Other system information:

profile: default/linux/amd64/17.1/no-multilib/hardened/selinux (stable)
groups: wheel audio video input me
USE="dbus peer_perms open_perms wayland -X alsa pulseaudio"
I don't have a login manager such as consolekit or elogind. [/url]

HandlingThrowback,

Welcome to Gentoo.

We need all of dmesg. What should be there but is missing is just as important as what in actually there.
When its filtered, its not possible to pick up missing entries.

Make friends with wgetpaste because dmesg is too big for a post.
Put dmesg onto a pastebin and post the link.

NeddySeagoon: I updated my original post with a link to the full dmesg

HandlingThrowback,

Your dmesg looks OK. I've seen problems with your touchpad as its an i2c_designware device.
Detection of i2c devices is difficult.

Getting back to USB devices and intermittent problems, I'm aware of several sources of pain.
Loading modules in the wrong order.
Loading modules for USB root hubs you don't have, interfering with the drives you do need.
USB bus powered devices overloading the bus.

We can investigate this by analysis.

Please put your kernel .config file onto a pastebin.

First, the info requested by NeddySeagoon is very important.

Second, I note (don't have the link handy) that a forum poster had trouble with libinput and went back to evdev, I did a new install last week and the mouse didn't work. I also got error messages "Your LiteOn USB keyboard is too slow >75ns". I had to power button out of the install. I re-entered the install via chroot, changed INPUT_DEVICES to "evdev", updated world and sure enough it works now. I provide this as information and potential fallback, but it is best if you can get libinput working. BTW, The keyboard is Microsoft branded, apparently really made by LiteOn. (It was the only one I could find in beige to match the old PS/2 leyboard).

OK, back to solving your problem the right way.
