When the user reboots the machine, by software or hardware, some USB errors will always occur, as USB communication is interrupted. In the event list you will see at least one “USB2 ctrl” error. When Axis Control was busy receiving parameters or info from the machine, also some “USB2 enc” errors will be in the list, like in the example below.


A machine only has USB-problems, when these errors occur in “NORMAL operation.

When there are more communication issues than check the articles about communication problems:
