In order to configure a J-Link to use the new USB identification method (reporting
the real serial number) simply select "Real SN" as USB identification method and
click the OK button. The same dialog also allows configuration of the IP settings of
the connected J-Link if it supports the Ethernet interface.
Note: When re-configuring older J-Links which use the old enumeration method
(USB identification: USB 0 - USB 3) you can only have 1 J-Link connected which uses
the old method at the same time. So re-configuration has to be done one at a time.
