X11/Thinkpad T430: partially drops input from USB devices after resume
I am using my laptop (lenovo T430, debian testing) regularly in a docking station. The dock has a USB keyboard, USB mouse and monitor
permanently attached. The laptops suspends from time to time, and _after_ resuming X11 or some other system component
the input from USB mouse and keyboard to be dropped/ignored partially. Symptoms are that the cursor does not move with
the mouse, however it will start moving again if I click any of the mouse buttons; or that the keyboard input is ignored until
I hit some arbitrary keys very rapidly. The USB amnesia starts again if I leave the input device untouched for some seconds.
The issue will not occur for newly connected devices or if I reconnect mouse/keyboard. The dock is not the issue as I can
reproduce the phenomenon with a USB mouse directly connected to the laptop.
I am looking for ways to correctly diagnose things to file a bug (against which package: xorg-input, kernel/driver, ...).
dmesg shows on device attachment/boot, e.g. for a cordless USB mouse:
