Application: Plan to use 2 USBTinyISP programmers connected to host machine to flash bootloader & firmware on two nano uC.

Problem statement: How to detect which programmer is connected to which uC so that correct firmware is flashed. Typically I use iSerial number to find the correct programmer but looks like that field reports just 0.

Is there a way to update the iSerial number and update the fw on the USBTinyISP?
