The 'fxload' tool contained in the examples provided with libusb is
actually useful and turns out to be the only way to load firmware into
some rather ancient EZ-USB microcontrollers made by Cypress (formerly
Anchor Chips).
The original 'fxload' tool from hotplug-linux has been abandonned long
ago and requires usbfs to be mounted in /proc/bus/usb/ (like it was in
Linux 2.4...).
Hence the best option is to package the modern 'fxload' from the libusb
examples which (unsurprisingly) uses libusb and works on modern
systems.
