Comment 62 for bug 82368

I've been able to make some more tracks with lsinput and input_events (many thanks to Stephan Bader).
The issue occur on box A, I'm connected to it from another pc via ssh (box B) to run lsinput and input_events tools.

lsinput only shows that the keyboard is disconnected then reconnected but inform what event is used :
/dev/input/event4
   bustype : BUS_USB
   vendor : 0x413c
   product : 0x2003
   version : 272
   name : "Dell Dell USB Keyboard"
   phys : "usb-0000:00:0b.0-4/input0"
   uniq : ""
   bits ev : EV_SYN EV_KEY EV_MSC EV_LED EV_REP

Then :
When I disconnect from my box A session then relog, nothing appear if I write something in a terminal for example. Only mouse events work (I can close a window, move the mouse pointer etc..)

input_events 4 show that even if nothing appear at screen before unplug/replug, the keyboard events seems well captured but nothing happen.
For example, striking "ls -ali" followed by the enter key in a box A terminal session when the issue is on, is well seen by input_events but it is neither applied nor displayed.

I join a small log from this try.
