PlugAndPlay action without any reason

Hello!

 

 Sometimes this Event is noticed:

 

The device 'HP LaserJet 1100 (MS)' (LPTENUM\Hewlett-PackardHP_LaserJet_1100\5&1d62032d&0&LPT1.4)
disappeared from the system without first being prepared for removal.

 

After that a
message popups:

 Hostprozess für Windows-Dienste wurde beendet und geschlossen.

I translate to English:

Host process for Windows-Services was ended and closed.

in the corresponding .wer File is noted:

ConsentKey=BEX
AppName=Computerbrowser
AppPath=C:\Windows\system32\svchost.exe

 

and it was not possible to start the Event-Viewer.

 

This happened without any corresponding user actions.

 

Have you an idea what to think about?
