So I think your fxload command is not correct.

# fxload -D /dev/bus/usb/002/013 -L niusbb_firmware.hex -s niusbb_loader.hx

I think you may want to try
# fxload -D /dev/bus/usb/002/013 -I niusbb_firmware.hex -s niusbb_loader.hex

You may have better luck with the linux-gpib project. They have a mailing
list as well.
