        If you are using an expansion board you should not modify the drivers with zadig. This is only for the firmware upgrade of Pysense/pytrack. Can you please uninstall the drivers for this device then install FTDI drivers from: http://www.ftdichip.com/Drivers/VCP.htm

              Two things 1) make sure nothing else has the serial port open 2) make sure you connect the jumper then press the reset button, before running the update tool

                  Yes the lopy should be plugged into the expansion board if you want to update the firmware.

                      The expansion board 2 does not have a firmware in the same way the Pysense/Pytrack do. On the expansion board the USB to Serial conversion is handled by a dedicated FTDI usb to serial chip. On the pysense/pytrack a PIC microcontroller does this (plus more) and thus needs firmware.

                          That is correct, the 1.17.0.b1 upgrade is for the LoPy. You do not need to
                          ever upgrade firmware for the expansion board 2
