When called from udev to load the FPGA firmware, make sure that this is
not the event generated for the first end-point of the existing two, as
we need to talk with the second one.
This is probably better done in the udev rules, but will be slightly
more complicated to apply only to the FPGA loading and not to USB
firmware loading.
