  • When was the server crash. Only event noteworth I see is at 2022-03-10 09:25:37, but the server did not crash. Windows just did disconnect all printers so server was disconnected from the printer.

    As long as you can see the interface the server is not crashed.

    Are all 9 printers on the same usb hub? Then I'd guess that the hub was disconnected. In linux I know this can happen on back EMI for example. Did the printers come back after this? Does windows still show the com ports in hardware manager?

    This is no server problem, it is just not getting the connection from windows any more. As soon as com port is available again it would then reconnect.
  • the printers are connected via 10 usb ports switch to a mini pc usb.
    it may be possible an error occured while windows update? 
    maybe not enough ram?
  • The log does not show enough informations to say more. All I can see is that most likely the hub got disconnected from windows as all printers were disconnected same time. Why windows did it can only windows logs tell, but there are so hard to read and interpret compared to linux. Updates are a possible reason, but not the only one. Linux disconnects also for electric problems like EMI or too much current usage, also I guess that this is a powered hub with 10 ports. But does it have enough power for all 10 printers - depends on printer. Some draw no current at all others can come close to 0,5A which is the official allowed maximum for usb 2.
