since a week or so, I have no more working usb mouse and keyboard (separate,
wired usb ones) on my Leap 15.3. ASUS laptop N550JK.

The curious thing is that if I first boot an old 15.1 install, mouse and
keyboard works, and if I just reboot on 15.3 (not power off), mouse and
keyboard start working in 15.3.

So on the morning I have to first start 15.1 (no need to login), and reboot on
15.3. odd.

of course the two devices used to work since ages and still works after the
double boot.

Looks like some thing on the device is not correctly initialized (firmware?)

* bug on last kernel, 5.3.18-59.34-default
* no bug on kernel 5.3.18-58.10-default

I didn't test all the kernels between these two
