J-Link / J-Trace (UM08001)
In general, there are two interfaces which can be used by J-Link, to connect to a
host: USB Full/Hi-Speed and Ethernet. When using USB, there are different ways in
which a J-Link can be identified on a host. The J-Link software and documentation
package comes with a configurator (JLinkConfig.exe) which allows you to configure
how a J-Link is identified on the host system when using USB.
In general, when using USB, there are three different ways in which a J-Link can be
identified:
•
•
Default configuration of J-Link is: Identification by serial number. Identification via
USB address is used for compatiblity and not recommended.
Background information
"USB address" really means changing the USB-Product Id (PID).
The following table shows how J-Links enumerate in the different identification
modes.
