J-Link / J-Trace (UM08001)
You can connect up to 4 J-Links / J-Traces to your PC. In this case, all J-Links / J-
Traces must have different USB-addresses. The default USB-address is 0.
In order to do this, 3 J-Links / J-Traces must be configured as described below. Every
J-Link / J-Trace need its own J-Link USB driver which can be downloaded from
www.segger.com.
This feature is supported by J-Link Rev. 5.0 and up and by J-Trace.
USB devices are identified by the OS by their product id, vendor id and serial number.
The serial number reported by J-Links / J-Traces is always the same. The product id
depends on the configured USB-address.

A different PID means that J-Link / J-Trace is identified as a different device, requir-
ing a new driver. The driver for a new J-Link device will be installed automatically.
The sketch below shows a host, running two application programs. Each application
communicates with one ARM core via a separate J-Link.
Connecting multiple J-Links / J-Traces to your PC
The vendor id (VID) representing SEGGER is always 1366
The product id (PID) for J-Link / J-Trace #1 is 101
The product id (PID) for J-Link / J-Trace #2 is 102 and so on.
