since a week or so, I have no more working usb mouse and keyboard (separate, wired ones) on my Leap 15.3.
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 initalized (firmware?)
devices are:
Bus 002 Device 010: ID 0461:0010 Primax Electronics, Ltd HP PR1101U / Primax PMX-KPR1101U Keyboard
Bus 002 Device 009: ID 093a:2510 Pixart Imaging, Inc. Optical Mouse
the system have no problem: I have the keyboard working in grub :-(, and both windows and openSUSE 15.1 boot restore the mouse.keyboard working since next shutdown (reboot is ok).
