Set the USB PID of the interface. As a configuration command, it can be used only before 'init'.

Set the @var{serial-number} of the interface, in case more than one adapter is connected to the host.
If not specified, serial numbers are not considered.
Note that there may be leading zeros in the @var{serial-number} string
that will not show in the Segger software, but must be specified here.
Debug level 3 output contains serial numbers if there is a mismatch.
